G6PD Quantitative (HM0040)

Description

G6PD Quantitative is a specialized blood test used to measure the activity level of the enzyme Glucose-6-Phosphate Dehydrogenase (G6PD) in red blood cells. This test helps diagnose G6PD deficiency, an inherited enzymatic disorder that can lead to hemolytic anemia, neonatal jaundice, and red blood cell breakdown after exposure to certain medications, infections, or foods such as fava beans. A quantitative G6PD assay provides an exact enzyme activity value, making it more reliable than screening methods for confirming deficiency, assessing severity, and guiding clinical management in newborns, children, and adults. It is commonly recommended in patients with unexplained anemia, jaundice, family history of G6PD deficiency, or before prescribing oxidant drugs. The test is essential for evaluating red cell enzyme function and preventing hemolytic complications. Based on major reference labs, quantitative G6PD is typically performed on whole blood using a kinetic spectrophotometric / kinetic 340 nm assay.

Pre-Test Instructions:

No fasting required
Collect in lavender-top (EDTA) tube; some labs may also accept yellow-top (ACD) or green-top (heparin) whole blood
Send whole blood in original tube; do not aliquot if possible
Mix gently by inversion after collection
Do not freeze the specimen; frozen samples may be rejected
Avoid clotted, hemolyzed, contaminated, or underfilled samples
Testing done during or soon after an acute hemolytic episode may give false-normal / spuriously high results because older deficient RBCs may already be destroyed; repeat testing later may be needed if clinically suspected
Inform the lab/doctor if patient is a newborn, has recent transfusion, or is in post-hemolytic recovery, as interpretation may be affected
