The G6PD Quantitative Test is a blood test that measures the level of glucose-6-phosphate dehydrogenase (G6PD) enzyme in red blood cells. G6PD is important for protecting red blood cells from damage and breaking down harmful substances. A deficiency in this enzyme can lead to hemolytic anemia, especially when exposed to certain medications, infections, or foods (like fava beans).
Unlike qualitative tests that give a simple “deficient or normal” result, the quantitative version measures the exact enzyme activity level, making it more accurate and useful in diagnosing partial deficiencies or assessing carriers, especially in females.

    Why It’s Done

    A G6PD Quantitative Test may be recommended for the following reasons:
    • Diagnose G6PD Deficiency: Especially if you or your child have symptoms of unexplained anemia, jaundice, or dark urine.
    • Before Prescribing Certain Medications: Some drugs (e.g., certain antibiotics, antimalarials, or chemotherapy agents) can trigger hemolysis in G6PD-deficient individuals.
    • Newborn Screening: In regions where G6PD deficiency is common.
    • Family History: If a close relative has G6PD deficiency.
    • Unexplained Hemolysis: In adults or children after illness, medication, or exposure to triggers.

    Preparation

    Generally, no special preparation is required for a G6PD Quantitative Test. However, consider the following:
    • Inform Your Doctor: Let your healthcare provider know about any recent infections, medications, or blood transfusions. These factors can affect the test result.
    • Avoid Testing During Acute Hemolysis: If possible, the test should not be done during an active episode of hemolysis or soon after a blood transfusion, as it may mask the deficiency.
    • Sample Type: The test requires a blood sample, usually taken from a vein in your arm
