Glucose-6-Phosphate Dehydrogenase (G6PD) analysis in whole blood using EDTA is a laboratory test used to determine G6PD enzyme levels in blood cells. This enzyme is essential for protecting red blood cells from oxidative damage by maintaining the balance of antioxidants within the cells. The test is commonly performed to diagnose G6PD deficiency, a genetic disorder that can lead to hemolysis (red blood cell breakdown) when exposed to certain triggers such as specific medications or foods. It is particularly recommended for individuals showing symptoms such as jaundice or anemia, or those with a family history of G6PD deficiency. The sample is collected in an EDTA-containing tube, and the test must be conducted under specific conditions to ensure accurate results. This analysis is an important tool for evaluating red blood cell health and detecting genetic disorders that may affect their function.
