Understanding Immunity Test Package
What is Immunity Test Package?
Strong immunity is crucial for fighting any infection. Some basic parameters such as immunoglobulin (antibodies) levels, vitamin D levels, iron levels, etc., can be a good indicator of the body's capabilities to fight back any viral or bacterial infection. This immunity health package helps you keep a check on these parameters and take action toward stronger immunity.
What does Immunity Test Package measure?
Contains 50 testsSerum Iron Studies Basic
The Serum Iron Studies Basic package measures the level of iron in the body. It comprises a series of blood tests, including a serum iron test that measures the level of iron in the blood, a Total Iron-Binding Capacity (TIBC) test that reflects the body's iron stores, an unsaturated iron binding capacity (UIBC) test that reflects binding of iron with transferrin which is the main protein that binds with iron, and transferrin saturation test that checks how much transferrin is saturated with iron.

Total Iron Binding Capacity
The Total Iron Binding Capacity test measures the ability of your blood to bind and transport iron, and therefore reflects your body's iron stores. TIBC correlates with the amount of transferrin, a protein, in your blood, that helps bind iron and facilitates its transportation in the blood. Usually, about one-third of the transferrin measured is being used to transport iron, and this is called transferrin saturation.
Iron, Serum
An Iron, Serum test determines iron levels in the blood and can help diagnose conditions like anemia, or iron overload in the body. People usually suffer from low iron levels in the blood if they prefer a diet that has low iron content, or if their body has trouble absorbing the iron from the foods or supplements they intake. Low iron levels can also occur due to intense blood loss or even during pregnancy. Similarly, an excess amount of iron in the blood can occur due to over-intake of iron supplements, blood transfusions, or if you are suffering from a condition called hemochromatosis (a rare genetic disorder that causes too much iron to build up in the body or cause problems in the body to remove excess iron).
Therefore, doctors often suggest an Iron, Serum to help check the status of your iron level, get valuable information about your nutritional well-being, detect potential health issues (if any), and take timely preventive measures.
Unsaturated Iron Binding Capacity
An Unsaturated Iron Binding Capacity test determines the reserve capacity of transferrin, i.e., the portion not yet saturated with iron. The iron-binding capacity of our body can be segregated into two parts – Total Iron Binding Capacity (TIBC) and Unsaturated Iron Binding Capacity (UIBC). UIBC refers to the capacity of transferrin, a protein that transports iron, to bind with additional iron. In easy terms, it represents the available "slots" on transferrin to carry iron molecules. Unlike iron saturation, which assesses the occupied slots, UIBC measures the unoccupied ones.
Transferrin Saturation
The Transferrin Saturation test determines an individual’s iron status by using the ratio of serum iron concentration and total iron binding capacity (TIBC) as a percentage. The test tells us how much iron in the blood is bound to transferrin, the main protein in the blood that binds to iron and transports it throughout the body. Under normal conditions, transferrin is one-third saturated with iron, so about two-thirds of its capacity is held in reserve. This test is often employed alongside others to evaluate iron levels and diagnose conditions like iron deficiency anemia if transferrin saturation is low or hemochromatosis (an iron overload disorder) if transferrin saturation is higher than normal.
ESR (Erythrocyte Sedimentation Rate)
An ESR test measures the rate at which red blood cells (erythrocytes) settle (sediment) in one hour at the bottom of a tube that contains a blood sample.
When there is inflammation in the body, certain proteins, mainly fibrinogen, increase in the blood. This increased amount of fibrinogen causes the red blood cells to form a stack (rouleaux formation) that settles quickly due to its high density, leading to an increase in the ESR.
An ESR test is a non-specific measure of inflammation and can be affected by conditions other than inflammation. This test cannot identify the exact location of the inflammation in your body or what is causing it. Hence, an ESR test is usually performed along with a few other tests to identify or treat possible health concerns.

CBC (Complete Blood Count)
The CBC (Complete Blood Count) test evaluates red blood cells (RBCs), white blood cells (WBCs}, and platelets. Each of these blood cells performs essential functions–RBCs carry oxygen from your lungs to the various body parts, WBCs help fight infections and other diseases, and platelets help your blood to clot–so determining their levels can provide significant health information. A CBC test also determines the hemoglobin level, a protein in RBC that carries oxygen from the lungs to the rest of your body. Evaluating all these components together can provide important information about your overall health.
Know more about CBC (Complete Blood Count)
Differential Leukocyte Count
- Differential Monocyte Count
- Differential Basophil Count
- Differential Eosinophil Count
- Differential Neutrophil Count
- Differential Lymphocyte Count
There are five types of WBCs: neutrophils, lymphocytes, monocytes, eosinophils, and basophils. A Differential Leukocyte Count test measures the percentage of each type of WBC in the blood. Leukocytes or WBCs are produced in the bone marrow and defend the body against infections and diseases. Each type of WBC plays a unique role to protect against infections and is present in different numbers.

Red Blood Cell Count
The Red Blood Cell Count test measures the total number of red blood cells in your blood. RBCs are the most abundant cells in the blood with an average lifespan of 120 days. These cells are produced in the bone marrow and destroyed in the spleen or liver. Their primary function is to help carry oxygen from the lungs to different body parts. The normal range of RBC count can vary depending on age, gender, and the equipment and methods used for testing.
Hb (Hemoglobin)
An Hb (Hemoglobin) test measures the concentration of hemoglobin protein in your blood. Hemoglobin is made up of iron and globulin proteins. It is an essential part of RBCs and is critical for oxygen transfer from the lungs to all body tissues. Most blood cells, including RBCs, are produced regularly in your bone marrow. The Hb test is a fundamental part of a complete blood count (CBC) and is used to monitor blood health, diagnose various blood disorders, and assess your response to treatments if needed.
Platelet Count
The Platelet Count test measures the average number of platelets in the blood. Platelets are disk-shaped tiny cells originating from large cells known as megakaryocytes, which are found in the bone marrow. After the platelets are formed, they are released into the blood circulation. Their average life span is 7-10 days.
Platelets help stop the bleeding, whenever there is an injury or trauma to a tissue or blood vessel, by adhering and accumulating at the injury site and releasing chemical compounds that stimulate the gathering of more platelets. A loose platelet plug is formed at the site of injury and this process is known as primary hemostasis. These activated platelets support the coagulation pathway that involves a series of steps, including the sequential activation of clotting factors; this process is known as secondary hemostasis. After this step, there is a formation of fibrin strands that form a mesh incorporated into and around the platelet plug. This mesh strengthens and stabilizes the blood clot so that it remains in place until the injury heals. After healing, other factors come into play and break the clot down so that it gets removed. In case the platelets are not sufficient in number or not functioning properly, a stable clot might not form. These unstable clots can result in an increased risk of excessive bleeding.
Total Leukocyte Count
The Total Leukocyte Count test measures the numbers of all types of leukocytes, namely neutrophil, lymphocyte, monocyte, eosinophil, and basophil, in your blood. Leukocytes or WBCs are an essential part of our immune system. These cells are produced in the bone marrow and defend the body against infections and diseases. Each type of WBC plays a unique role to protect against infections and is present in different numbers.
Hematocrit
The Hematocrit test measures the proportion of red blood cells (RBCs) in your blood as a percentage of the total blood volume. It is a crucial part of a complete blood count (CBC) and helps in assessing your blood health. RBCs are responsible for carrying oxygen from the lungs to different parts of the body. The hematocrit test provides valuable information about your blood's oxygen-carrying capacity.
Higher-than-normal amounts of RBCs produced by the bone marrow can cause the hematocrit to increase, leading to increased blood density and slow blood flow. On the other hand, lower-than-normal hematocrit can be caused by low production of RBCs, reduced lifespan of RBCs in circulation, or excessive bleeding, leading to a reduced amount of oxygen being transported by RBCs. Monitoring your hematocrit levels is essential for diagnosing and managing various blood-related disorders.
Mean Corpuscular Volume
The Mean Corpuscular Volume test measures the average size of your red blood cells, which carry oxygen through your body. This test tells whether your RBCs are of average size and volume or whether they are bigger or smaller.
Mean Corpuscular Hemoglobin
An MCH test measures the average amount of hemoglobin in a single red blood cell (RBC). Hemoglobin is an iron-containing protein in RBCs, and its major function is to transport oxygen from the lungs to all body parts. This test provides information about how much oxygen is being delivered to the body by a certain number of RBCs.
Mean Corpuscular Hemoglobin Concentration
An MCHC test measures the average amount of hemoglobin in a given volume of RBCs. MCHC is calculated by dividing the amount of hemoglobin by hematocrit (volume of blood made up of RBCs) and then multiplying it by 100.
Mean Platelet Volume
An MPV test measures the average size of the platelets in your blood. Platelets are disk-shaped tiny cells originating from large cells known as megakaryocytes, which are found in the bone marrow. After the platelets are formed, they are released into the blood circulation. Their average life span is 7-10 days.
Platelets help stop bleeding whenever there is an injury or trauma to a tissue or blood vessel by adhering and accumulating at the injury site, and by releasing chemical compounds that stimulate the gathering of more platelets. After these steps, a loose platelet plug is formed at the site of injury, and this process is known as primary hemostasis. These activated platelets support the coagulation pathway that involves a series of steps including the sequential activation of clotting factors; this process is known as secondary hemostasis. After this, there is a formation of fibrin strands that form a mesh incorporated into and around the platelet plug. This mesh strengthens and stabilizes the blood clot so that it remains in place until the injury heals. After healing, other factors come into play and break the clot down so that it gets removed. In case the platelets are not sufficient in number or are not functioning properly, a stable clot might not form. These unstable clots can result in an increased risk of excessive bleeding.
PDW
The PDW test reflects variability in platelet size, and is considered a marker of platelet function and activation (clot formation in case of an injury). This marker can give you additional information about your platelets and the cause of a high or low platelet count. Larger platelets are usually younger platelets that have been recently released from the bone marrow, while smaller platelets may be older and have been in circulation for a few days. Higher PDW values reflect a larger range of platelet size, which may result from increased activation, destruction and consumption of platelets.
RDW CV
The RDW CV test which is part of red cell indices, helps identify characteristics of red blood cells. RDW (red cell distribution width) measures the variations in the sizes of red blood cells, indicating how much they differ from each other in a blood sample. RDW is expressed as RDW-CV, a coefficient of variation. A higher RDW may suggest more variation in red cell sizes, while a lower RDW indicates more uniform red cell sizes.
Absolute Leucocyte Count
- Absolute Monocyte Count
- Absolute Eosinophil Count
- Absolute Neutrophil Count
- Absolute Basophil Count
- Absolute Lymphocyte Count
The Absolute Leucocyte Count test measures the total number of white blood cells (leucocytes) in the given volume of blood. It examines different types of white blood cells such as neutrophils, lymphocytes, monocytes, basophils and eosinophils. These cells tell about the status of the immune system and its ability to fight off infections and other conditions like inflammation, allergies, bone marrow disorders etc.

CRP (C-Reactive Protein), Quantitative
The CRP test measures the levels of C-reactive protein in your body. This test helps detect the presence of inflammation in the body. It is a non-specific test as it cannot diagnose a condition by itself or determine its exact location or cause.
CRP is an acute phase reactant protein produced by the liver in response to an inflammation in the body. This inflammation may be due to tissue injury, infection, autoimmune diseases, or cancer. CRP levels are often increased before the onset of other symptoms of inflammation, such as pain, redness, fever, or swelling. These levels fall as the inflammation subsides.

Vitamin D (25-Hydroxy)
The Vitamin D (25-Hydroxy) test measures the levels of vitamin D in the body. It is an essential nutrient that can be synthesized in the body upon healthy exposure to sunlight or absorbed from dietary sources. It majorly exists in two forms: Vitamin D2 (ergocalciferol) and Vitamin D3 (cholecalciferol). Vitamin D2 is present in plants, such as yeast or mushrooms, and is available as a supplement in fortified foods, and vitamin D3 is found in foods like cheese, green vegetables, mushrooms, egg yolks, and fatty fish.
Both forms of vitamin D (D2 and D3) need to undergo some chemical changes before being available for use in the body. These chemical changes take place in the liver or kidneys.The levels of 25-hydroxy Vitamin D in blood is considered the best parameter to assess vitamin D status of the body. A Vitamin D (25-Hydroxy) measures the level of Total 25-OH vitamin D (D2+D3) , but it does not differentiate between the two forms as it is the major form of vitamin D that circulates in the blood.
Know more about Vitamin D (25-Hydroxy)
LFT (Liver Function Test)
An LFT (Liver Function Test) helps determine the health of your liver by measuring various components like enzymes, proteins, and bilirubin. These components help detect inflammation, infection, diseases, etc., of the liver and monitor the damage due to liver-related issues.
Know more about LFT (Liver Function Test)
Gamma Glutamyl Transferase
Gamma-Glutamyl Transferase (GGT) is an enzyme found in various organs, with the highest concentration in the liver. Usually, this enzyme is present in low levels in the blood. However, when there is liver damage or disease, GGT is released into the bloodstream, causing an increase in GGT levels. In addition to the liver, GGT can also be elevated in conditions affecting the bile ducts or the pancreas. It is usually, the first liver enzyme to rise in the blood when there is any damage or obstruction in the bile duct, making it one of the most sensitive liver enzyme tests for detecting bile duct problems.
SGPT
An SGPT test measures the amount of ALT or SGPT enzyme in your blood. ALT is most abundantly found in the liver but is also present in smaller amounts in other organs like the kidneys, heart, and muscles. Its primary function is to convert food into energy. It also speeds up chemical reactions in the body. These chemical reactions include the production of bile and substances that help your blood clot, break down food and toxins, and fight off an infection.
Elevated levels of ALT in the blood may indicate liver damage or injury. When the liver cells are damaged, they release ALT into the bloodstream, causing an increase in ALT levels. Therefore, the SGPT/ALT test is primarily used to assess the liver's health and to detect liver-related problems such as hepatitis, fatty liver disease, cirrhosis, or other liver disorders.
Alkaline Phosphatase (ALP)
An Alkaline Phosphatase (ALP) test measures the quantity of ALP enzyme present throughout the body. The main sources of this enzyme are the liver and bones. It exists in different forms depending on where it originates, such as liver ALP, bone ALP, and intestinal ALP. In the liver, it is found on the edges of the cells that join together to form bile ducts.
ALP levels can be increased during pregnancy as it is found in the placenta of pregnant women. It is also higher in children because their bones are in the growth phase. ALP is often high during growth spurts (a short period when an individual experiences quick physical growth in height and body weight).
SGOT
An SGOT test measures the levels of serum glutamic-oxaloacetic transaminase (SGOT), also known as aspartate aminotransferase (AST), an enzyme produced by the liver. SGOT is present in most body cells, most abundantly in the liver and heart. The primary function of this enzyme is to convert food into glycogen (a form of glucose), which is stored in the cells, primarily the liver. The body uses this glycogen to generate energy for various body functions.
Protein Total, Serum
- Albumin/Globulin Ratio, Serum
- Protein Total
- Serum Albumin
- Globulin, Serum
The Protein Total, Serum test measures the amount of proteins in the body. Proteins are known as the building blocks of all cells and tissues. They play a crucial role in the growth and development of most of your organs and in making enzymes and hormones. There are two types of proteins found in the body, namely albumin and globulin. About 60% of the total protein is made up of albumin, which is produced by the liver. It helps to carry small molecules such as hormones, minerals, and medicines throughout the body. It also serves as a source of amino acids for tissue metabolism. On the other hand, globulin is a group of proteins that are made by the liver and the immune system. They play an important role in liver functioning, blood clotting, and fighting off infections.
This further contains
Bilirubin (Total, Direct and Indirect)
- Bilirubin Direct
- Bilirubin Total
- Bilirubin Indirect
The Bilirubin (Total, Direct and Indirect) test measures the level of three forms of bilirubin such as total bilirubin, direct (conjugated bilirubin), and indirect (unconjugated) bilirubin in the blood. Total bilirubin represents the sum of direct and indirect bilirubin. Direct bilirubin is the water-soluble form of bilirubin that has been processed by the liver via a conjugation process with glucuronic acid and is ready to be excreted into the bile ducts and ultimately into the intestines. Indirect bilirubin is the water-insoluble form of bilirubin that has not yet been processed by the liver and is bound to albumin in the blood. It is formed in the spleen and liver during the breakdown of hemoglobin from old or damaged red blood cells and cannot be excreted directly by the liver. Instead, it is transported to the liver, where it undergoes conjugation to become direct bilirubin.
Getting tested with the Bilirubin (Total, Direct and Indirect) test provides valuable information into various aspects of liver function, bile duct health, and the body’s ability to break down and eliminate bilirubin.
This further contains
Thyroid Profile Total (T3, T4 & TSH)
The Thyroid Profile Total (T3, T4 & TSH) measures the levels of three hormones in the blood, namely triiodothyronine hormone (T3) total, thyroxine hormone (T4) total, and thyroid-stimulating hormone (TSH). T3 and T4 are thyroid hormones that help regulate metabolism and energy levels in the body. On the other hand, TSH is produced by the pituitary gland and stimulates the thyroid gland to produce T3 and T4 hormones. The serum levels of the thyroid hormones and TSH have an inverse relationship, i.e., low T4 (as observed in hypothyroidism) and high T4 (as seen in hyperthyroidism) levels are associated with high and low TSH levels, respectively.
Know more about Thyroid Profile Total (T3, T4 & TSH)
Thyroxine - Total
The Thyroxine - Total test measures both the bound and unbound/free form of thyroxine (T4) hormone in the blood. T4 exists in the blood in two forms: bound (attached to proteins) and free (not attached to proteins). Most of the T4 circulating in the blood is bound to proteins and only a small part is free. It is necessary to maintain a fine balance of these forms to ensure the proper functioning of the body.
Triiodothyronine Total
The Triiodothyronine Total test measures triiodothyronine, also known as T3, hormone that is produced by the thyroid gland. T3 hormone plays an important role in regulating the body's metabolism, energy levels, and growth & development. It exists in the blood in two forms: free T3 and bound T3. Free T3 is not bound to proteins in the blood and is the active form of T3. Whereas, bound T3 is bound to proteins, such as albumin and thyroid hormone binding globulin (THBG), which prevent it from entering the body tissues.
TSH (Thyroid Stimulating Hormone) Ultrasensitive
The TSH (Thyroid Stimulating Hormone) Ultrasensitive test measures the levels of TSH hormone in the blood. TSH is produced by the pituitary gland located in the brain. Its function is to stimulate and regulate the functioning of the thyroid gland. It signals the thyroid gland to increase or decrease the production of thyroid hormones T3 and T4 (essential for regulating our body’s metabolism, temperature, heart rate, and growth) when their levels are low or high, respectively. Therefore, when the levels of T3 & T4 decrease, the pituitary gland is stimulated to release TSH. This high TSH level, in turn, stimulates the thyroid gland to release more thyroid hormones (T3 & T4); the vice-versa happens when the levels of thyroid hormones increase.
KFT with Electrolytes (Kidney Function Test with Electrolytes)
The KFT with Electrolytes (Kidney Function Test with Electrolytes) test determines the health of your kidneys. It evaluates parameters such as creatinine, blood urea nitrogen (BUN), uric acid, electrolytes (sodium, potassium, and chloride), blood urea and BUN/ creatinine ratio. This test also helps diagnose possible kidney disorders like inflammation, infection, or functional damage.
Know more about KFT with Electrolytes (Kidney Function Test with Electrolytes)
Serum Creatinine
The Serum Creatinine test measures the level of creatinine in the blood. Creatinine is a byproduct of muscles’ wear and tear during energy production. The kidneys remove it from the body by filtering it from the blood and releasing it into the urine. Therefore, blood creatinine levels indicate how well the kidneys are functioning in filtering and removing waste products from the blood. Generally, higher creatinine levels in the blood may indicate reduced kidney function, while lower levels may suggest decreased muscle mass.
Uric Acid
An Uric Acid test determines the level of uric acid in your body. Uric acid is a nitrogenous compound produced by the metabolic breakdown of purine. Purines are present as nitrogenous bases in the DNA and are also found in food like red meat and seafood.
Most uric acid dissolves in the blood and goes into your kidneys. From there, it passes through your body via the urine. Decreased elimination of uric acid is often a result of impaired kidney function due to kidney disease. In many cases, the exact cause of excess uric acid is unknown. Doctors seldom need to test for low levels of uric acid.
Blood Urea Nitrogen
The Blood Urea Nitrogen test measures the levels of urea nitrogen in the blood. Blood urea is a waste product that is formed in the liver when you eat food and the protein is metabolized into amino acids. This process leads to the production of ammonia that is further converted into urea. Both ammonia and urea are nitrogenous compounds. Your liver releases urea into the blood which is then carried out to the kidneys. In the kidneys, urea is filtered from the blood and flushed out of the body via urine. This is a continuous process, so a small amount of urea nitrogen always remains in the blood.
In the case of a kidney or liver disease, there is a change in the amount of urea present in the blood. If your liver produces urea in an increased amount or if there is any problem in kidney functioning, there might be difficulty in filtering out the waste products from the blood, which can result in increased urea levels in the blood.
BUN/Creatinine Ratio
The BUN/Creatinine Ratio test helps compare the levels of blood urea nitrogen to that of creatinine in your body. Urea is a waste product that is formed in the liver when you eat protein, which is then metabolized into amino acids. This process leads to the production of ammonia that is further converted into urea. Later, the urea is passed out of your body through the urine. On the other hand, creatinine is a byproduct produced by muscles during energy production. Therefore, the more muscle you have, the more creatinine your body produces. The kidneys remove both the urea and creatinine via urine, and this test determines how well your kidneys are functioning.
Blood Urea
The Blood Urea test measures the level of urea in the blood. Urea is a byproduct of protein metabolism. Proteins you consume in your diet are digested and converted into amino acids, which are then utilized by the body. This metabolic process produces a toxic byproduct known as ammonia. Ammonia is then rapidly converted into urea by your liver. Urea is comparatively less toxic than ammonia and is transported to the kidneys via the blood. The kidneys then filter it out through the urine. This process continues and the body keeps producing and eliminating urea, maintaining its low and steady levels in the blood.
Sodium
-
By producing hormones that control the elimination of sodium through urine, such as natriuretic peptides and aldosterone.
-
By producing hormones that prevent water loss, such as antidiuretic hormone (ADH).
-
By controlling thirst (an increase in blood sodium level can make you thirsty and cause you to drink water, returning your sodium to normal).
The Sodium test measures the amount of sodium in your body. Sodium is present in all body fluids and is found in the highest concentration in the extracellular fluid. The body absorbs the required amount of sodium through dietary salts, and the kidneys eliminate the remaining sodium. The body keeps your blood sodium within a regular and steady range by following three mechanisms:
These mechanisms regulate the amount of water and sodium in the body and control blood pressure by keeping the amount of water in check. When the sodium level in the blood changes, the water content in your body changes. These changes can be associated with dehydration, edema, and changes in blood pressure.
Chloride
The Chloride test measures the amount of chloride in your body. Chloride is present in all body fluids and is found in the highest concentration in the blood and extracellular fluid (fluid present outside the cells). The body gets most of the chloride through dietary salt (sodium chloride or NaCl) and a small amount through other food items. The required amount of chloride is absorbed in the body and the excess amount is excreted by the kidneys through urine. When the chloride is combined with sodium it is mostly found in nature as salt. Chloride generally increases or decreases in direct relationship to sodium but may also change without any changes in sodium levels when there are problems with the body's pH. Usually, the normal blood chloride level remains steady with a slight fall after meals (because the stomach produces hydrochloric acid using chloride from the blood after we eat food).
Potassium
The Potassium test measures the levels of potassium in your body. Potassium is one of the key electrolytes that helps in the functioning of the kidneys, heart, nerves, and muscles. It also balances the effect of sodium and helps keep your blood pressure normal. The body absorbs the required amount of potassium from the dietary sources and eliminates the remaining quantity through urine. Potassium level is typically maintained by the hormone aldosterone. Aldosterone acts on the nephrons present in the kidneys and activates the sodium-potassium pump that helps the body reabsorb sodium and excrete potassium. This aids in maintaining a regular and steady potassium level in the blood.
