Creatinine with eGFR (18 Years & Above) near me in Secunderabad

The Serum Creatinine test measures the creatinine level, a byproduct produced by the wear and tear of muscles during energy production. Since kidneys help filter creatinine, this test helps determine how well your kidneys work. Usually, high levels of creatinine in the blood signal diminished kidney function. At the same time, low levels may indicate decreased muscle mass.

What Do the Results Mean?

Pathological Factors 

Physiological Factors

🧒 Age: Creatinine levels may decrease with age (due to reduction in muscle mass).

🫄 Pregnancy: Slightly lower levels can be seen due to physiological changes in kidney function during pregnancy.

Lifestyle Factors

🥗 Diet: High protein intake may transiently increase creatinine.

🏋️ Exercise: Intense physical activity can temporarily elevate creatinine levels.

💊 Medications: Some medicines, such as NSAIDs, antibiotics, or certain blood pressure medications, may influence kidney function and creatinine levels.

What Do Normal Serum Creatinine Levels Mean?

Normal serum creatinine levels indicate that the kidneys are functioning properly and effectively filtering waste products from the blood.

What Do High Levels of Serum Creatinine Indicate?

High serum creatinine may indicate impaired kidney function, dehydration, urinary tract obstruction, or other conditions affecting renal health.

What to Do if Your Serum Creatinine Is Higher Than Normal?

If your creatinine level is higher than normal, consult your doctor for proper guidance. They may recommend additional tests, lifestyle adjustments, medication review, or referral to a nephrologist.

What Do Low Levels of Serum Creatinine Indicate?

Low levels are uncommon but may indicate low muscle mass, malnutrition, or liver disease. Always discuss results with your healthcare provider.

Can Serum Creatinine Results Be Inaccurate?

Yes, serum creatinine results can sometimes be inaccurate. Factors such as severe muscle loss, certain medications or supplements, and variations or errors in laboratory test methodologies can affect the accuracy of the results.

What Factors Can Affect Serum Creatinine Results?

Though a reliable test, several factors can influence accuracy:

• Muscle mass, age, sex
• Diet, hydration status
• Medications affecting kidney function
• Severe illness or trauma
• Hyperbilirubinemia

What Follow-Up Tests May Be Required?

Depending on your serum creatinine results, your doctor may recommend additional tests to get a clearer picture of kidney health. These can include urine tests, such as urine protein or microalbumin or cystatin C, to detect early kidney damage; an eGFR calculation to estimate kidney filtration efficiency; kidney imaging, like an ultrasound, to check for structural abnormalities; and electrolyte or kidney function panels to assess overall kidney performance and detect any imbalances. Fasting is not recommended for this test, you can eat and drink as per your daily routine.

Table: Tests Commonly Ordered Alongside the Serum Creatinine Test

The Glomerular Filtration Rate, Estimated (eGFR) test is a critical measurement used to assess kidney function by estimating the rate at which blood is filtered through the glomeruli, the tiny structures in the kidneys responsible for filtering waste products and excess fluids from the bloodstream. It provides a numerical value that indicates how effectively the kidneys are performing this essential filtration process. A normal eGFR suggests healthy kidney function, while a lower eGFR may indicate reduced kidney function, which can be indicative of various conditions such as chronic kidney disease (CKD), diabetes-related kidney damage (diabetic nephropathy), hypertension-related kidney damage, or other kidney disorders. eGFR is typically calculated using a formula that takes into account factors such as age, gender, race, and serum creatinine levels—a waste product from muscle activity that the kidneys remove from the blood. Doctors use eGFR results to diagnose kidney disease, assess its severity, monitor progression over time, and determine appropriate treatment strategies to manage and potentially slow the decline in kidney function. Regular monitoring of eGFR is crucial for individuals at risk of kidney disease or those with pre-existing conditions to ensure early detection and timely intervention, thereby optimizing kidney health and overall well-being.
