Used in biomedical research to quantify levels of glucose-6-phosphate dehydrogenase (G6PD) enzyme in human samples. Helps assess G6PD activity indirectly, supporting diagnosis and monitoring of G6PD deficiency, a common genetic enzyme disorder linked to hemolytic anemia. Widely applied in clinical labs and research studies to evaluate red blood cell metabolism, oxidative stress responses, and drug-induced hemolysis risk. Also used in population screening and epidemiological studies to identify at-risk individuals. The ELISA format allows for high-throughput, specific, and sensitive detection of the enzyme in serum, plasma, or lysed blood samples.
