Glucose-6-Phosphate Dehydrogenase (G-6-PD),Qualitative
Understanding Glucose-6-Phosphate Dehydrogenase (G-6-PD),Qualitative
What is Glucose-6-Phosphate Dehydrogenase (G-6-PD),Qualitative?
The Glucose-6-Phosphate Dehydrogenase (G-6-PD),Qualitative is a qualitative blood test for detection of glucose-6-phosphate dehydrogenase (G-6-PD) enzyme deficiency, an inherited condition affecting red blood cells. It helps detect hemolytic anemia, especially after exposure to specific triggers, such as certain medications, foods, and infections.
Glucose-6-phosphate dehydrogenase (G-6-PD) is an enzyme that plays a crucial role in the proper functioning of red blood cells by protecting them from oxidative damage. A deficiency in this enzyme can lead to hemolytic anemia. In this condition, red blood cells break down faster than the body can produce them. This is particularly triggered by factors such as infections, certain medications, or the consumption of fava beans, a condition known as "favism”.
The Glucose-6-Phosphate Dehydrogenase (G-6-PD),Qualitative test identifies if an individual has enough G-6-PD enzyme activity. Knowing their deficiency status allows individuals to manage their condition by avoiding triggers known to precipitate hemolytic episodes.
The Glucose-6-Phosphate Dehydrogenase (G-6-PD),Qualitative test is recommended for individuals showing signs and symptoms of hemolytic anemia, like fatigue, jaundice, dark urine, shortness of breath, and an enlarged spleen. It is especially useful for those at higher risk, such as males, African Americans, or those with a family history of G-6-PD deficiency. Doctors may also suggest this test before giving certain medications that can cause oxidative stress, like some antibiotics, antimalarials, or sulfa drugs. Additionally, the test is used to screen newborns in areas where G-6-PD deficiency is common.
Before a G6PD test, avoid certain medications (sulfonamides, antimalarials, aspirin) and fava beans, as they can affect test results. If you've had a recent hemolytic episode or blood transfusion, consult your doctor and wait for a few weeks before testing to ensure accuracy. Fasting is not required, but follow your doctor’s instructions.
Lab test results may vary across laboratories. Do not self-medicate. Always consult the doctor to understand the test results correctly. The insights from Glucose-6-Phosphate Dehydrogenase (G-6-PD),Qualitative test will help doctors formulate the overall treatment plans.
What is Glucose-6-Phosphate Dehydrogenase (G-6-PD),Qualitative used for?
The Glucose-6-Phosphate Dehydrogenase (G-6-PD),Qualitative test is done:
- To diagnose G6PD deficiency, especially in individuals with unexplained hemolytic anemia.
- To evaluate if hemolytic anemia is due to G-6-PD deficiency, especially after exposure to certain drugs, infections, or foods (e.g., fava beans).
- To help identify the cause of neonatal jaundice.
- To monitor individuals from high-risk ethnic backgrounds who may be at risk of hemolytic episodes.
- To assess G6PD enzyme activity before administering medications that may trigger hemolysis, especially antimalarials.
- To assess the effectiveness of treatments for conditions related to G-6-PD deficiency, such as during or after a hemolytic episode.
What does Glucose-6-Phosphate Dehydrogenase (G-6-PD),Qualitative measure?
The Glucose-6-Phosphate Dehydrogenase (G-6-PD),Qualitative test measures the activity of the G6PD enzyme in red blood cells. This enzyme is essential for preventing RBCs from oxidative stress. It achieves this by helping to regenerate glutathione, a molecule that neutralizes harmful oxidative substances. When there is not enough G6PD, red blood cells become more vulnerable to damage. This damage can be triggered when someone gets an infection, takes certain medicines (like antibiotics or antimalarials), or eats specific foods like fava beans.
This test helps determine if someone has G6PD deficiency, which is important for managing conditions caused by oxidative stress. If the test shows low or no G6PD enzyme activity, it can explain why someone has recurring issues like hemolytic episodes (where red blood cells break down), jaundice (yellowing of the skin and eyes), and other symptoms. It also helps doctors and patients avoid things that could trigger these problems in the future.

Interpretations
The qualitative test checks for fluorescence under UV light. If no fluorescence is detected, the test is declared positive.
