Interpretive Comments: Glucose-6-phosphate dehydrogenase (G6PD) is an enzyme in the pentose phosphate pathway, a metabolic pathway that supplies reducing energy to cells. Patients with G6PD deficiency are at risk of hemolytic anemia in states of oxidative stress triggered by viral or bacterial infections, antimalarial drugs (primaquine) or exposure to certain foods (fava beans).
Special Processing: All test requests for the G-6-PD assay will include a CBC and reticulocyte enumeration.
Comments:  
Method of Analysis: Enzymatic rate method on chemistry analyzer.
Critical Information Required:  
Storage & Shipment: Ship sample at room temperature.

Samples must be received in laboratory for testing within 24 hours of sample collection.
System Codes: 
Cerner
G6PDA
