This testing involves sequencing of the G6PD gene associated with Glucose -6-Phosphate dehydrogenase deficiency. Indications for Test: Candidates for this test are patients showing features consistent with G6PD (anemia, increased LDH, decreased haptoglobin, and presence of Heinz bodies). Biochemical G6PD enzymatic assays may appear normal during an acute hemolytic episode Families with members who have known G6PD mutations are also strong candidates.

Complete the attached test requisition and submit with the specimen.
