Glucose 6 Phosphate Dehydrogenase G6PD (Quant)

The Glucose-6-Phosphate Dehydrogenase (G6PD) Quantitative Test is a precise diagnostic tool used to measure the exact level of enzyme activity within your red blood cells.Unlike a qualitative screen, which simply indicates if a deficiency exists, the quantitative analysis provides a specific numerical value (usually expressed in Units per gram of Hemoglobin). In clinical practice, the G6PD Quantitative test is a foundational safety metric. It is vital for patients before they begin specific drug therapies—such as antimalarials (Primaquine) or certain antibiotics (Sulfonamides)—that can cause sudden, catastrophic red blood cell destruction (hemolysis).
