What the G6PD test checks
There are two broad types of test. A qualitative screen, such as the fluorescent spot test, reports "normal" or "deficient". A quantitative assay measures the actual enzyme activity, usually in units per gram of haemoglobin (U/g Hb), and is better at picking up women with intermediate levels. Depending on the method your doctor needs, the sample is processed in-house or at a partner reference laboratory; we'll tell you which when you book.
G6PD deficiency is inherited on the X chromosome. Men with the gene are usually clearly deficient. Women can range from normal to deficient, which is why the quantitative test matters for them.
Why your doctor may order it
- before giving primaquine or tafenoquine for vivax malaria, which can cause haemolysis in deficient people
- before medicines such as dapsone or rasburicase
- jaundice in a newborn, especially if it is early or severe
- an episode of dark urine, jaundice and anaemia after an infection or a new medicine
- a family member already known to be G6PD deficient
How to prepare
No fasting. The key thing is timing. If you've had a haemolytic episode in the last few weeks, the result can come out falsely normal, because the young red cells made afterwards carry more enzyme. A recent blood transfusion causes the same problem. Doctors often prefer to test, or repeat the test, around three months after an episode or transfusion. Tell us the dates.
Sample type and report time
A small venous sample in a purple-top EDTA tube. Home collection works well for this test. Results are usually ready the same day or the next day; if the sample goes to a partner laboratory we'll give you the expected date.
Understanding your results
A "deficient" screen or low quantitative activity means your red cells are more vulnerable to oxidative stress. Normal activity in a man generally means he is not deficient, as long as there's been no recent haemolysis or transfusion. Intermediate values in women need interpretation by the doctor. The range printed on your report is the one that applies, as cut-offs vary by lab and method.
Most deficient people live normally by avoiding known triggers: specific medicines, fava beans and naphthalene mothballs. Your doctor will give you the list that applies to you, and reads the result alongside your symptoms and other tests.
FAQ
Is G6PD deficiency curable?
It's a lifelong inherited trait, not an infection. Avoiding triggers prevents most problems.
Should my newborn have a G6PD test?
Many paediatricians in India recommend it, especially with jaundice or a family history. Your child's doctor will advise.
Is there a G6PD test near me in Banur?
Yes. If you are looking for a G6PD test near me in Banur, we collect the sample at Alpha Laboratory or at home.
Can a woman be G6PD deficient?
Yes, though it is less common and often partial. A quantitative test gives the clearer answer.
