G6PD (Quantitative)

The G6PD (Quantitative) test measures the activity of the enzyme glucose-6-phosphate dehydrogenase in red blood cells and reports a numeric value (commonly U/g Hb) that indicates enzyme function. This enzyme is essential for protecting red blood cells from oxidative stress; low activity (G6PD deficiency) can lead to acute hemolysis when exposed to certain drugs, infections, or foods (for example, fava beans).

This quantitative assay is used to confirm deficiency, grade its severity, and identify intermediate activity—important for detecting heterozygous females who may have partial deficiency. Performed on an EDTA whole blood sample, results are provided by Dubai‑certified laboratories and are used to guide medication choices, dietary advice, family screening, and newborn care to prevent hemolytic episodes.

• Glucose-6-Phosphate Dehydrogenase (G6PD) activity (U/g Hb)
• Hemoglobin (g/dL) — used for normalization
• G6PD activity interpretation (Normal / Intermediate / Deficient)

• Newborn screening or unexplained neonatal jaundice
• Before prescribing oxidant medications (e.g., primaquine, dapsone, sulfonamides, rasburicase)
• After unexplained hemolytic anemia or acute hemolysis episodes
• Family history of G6PD deficiency or known carrier status
• Prior to occupational or travel exposure where antimalarials may be required

• Accurate quantitative measurement to determine severity of deficiency
• Detects intermediate activity in female carriers that qualitative tests may miss
• Guides safe medication and dietary choices to prevent hemolysis
• Convenient at‑home sample collection with Dubai‑certified lab reporting
• Fast, actionable results to inform physicians and family screening

• At‑home collection of EDTA whole blood (venous preferred; capillary may be accepted)
• No fasting required for the test
• Avoid testing within 3 months after a blood transfusion (transfusion can mask deficiency)
• Inform the collector of recent severe hemolysis or high reticulocyte counts (may affect results)
