G6PD Qualitative Reflex Quantitative Estimation

This two-step test initially screens for G6PD deficiency using a qualitative method and confirms with quantitative analysis if deficient.

To detect glucose-6-phosphate dehydrogenase deficiency, which can cause hemolytic anemia in response to certain drugs or foods.

A blood sample is screened using a qualitative test. If abnormal, a quantitative enzyme activity assay is conducted.

Low G6PD activity confirms deficiency. Carriers may show intermediate results, especially females due to X-linked inheritance.

Avoid testing during or immediately after a hemolytic episode for accurate results.
