G6PD Deficiency Test – Understanding a Key Enzyme Deficiency
The G6PD Deficiency Test screens for glucose-6-phosphate dehydrogenase (G6PD), an enzyme critical for red blood cell function. This test is essential for diagnosing G6PD deficiency, a common inherited enzyme deficiency that affects the red blood cells.
What is G6PD Deficiency?
G6PD deficiency is a genetic disorder that affects red blood cells, making them more prone to breaking down (hemolysis) when exposed to specific triggers like infections, certain medications, or foods such as fava beans.
Indications for G6PD Deficiency Test:
● Unexplained hemolysis: If there is unexplained anemia (fatigue, pallor, jaundice) following an infection or exposure to certain drugs.
● Newborn screening: A routine test in areas where the deficiency is common.
● Family history of hemolytic anemia: If a family member has G6PD deficiency, genetic screening may be recommended.
Normal Range:
● Normal test result: No deficiency detected, meaning the G6PD enzyme levels are within the expected range.
Abnormal Test Significance:
● Deficient G6PD levels: Indicates G6PD deficiency, which may lead to hemolytic episodes triggered by certain medications, foods, or infections.
Management:
● Avoid triggers: Patients with G6PD deficiency should avoid specific drugs (e.g., sulfonamides, aspirin), fava beans, and infections that could lead to hemolysis.
● Supportive care: In the case of hemolytic anemia, treatment may include blood transfusions or hydration.
Price in India:
● Approx. 400- 600 INR
FAQ Section:
What happens if I have G6PD deficiency?
If you have G6PD deficiency, your red blood cells are more likely to break down when exposed to certain triggers, leading to hemolytic anemia.
Is G6PD deficiency treatable?
While there is no cure for G6PD deficiency, avoiding known triggers can help prevent hemolytic episodes.
How can I test for G6PD deficiency?
The test is done using a blood sample. It’s often part of routine newborn screening or can be done if there’s a family history of the condition.
