Other RBC enzyme activity assays you performed: Glucose-6-phosphate dehydrogenase, Gluthathione reductase
Method to perform G6PD activity assay: Spectrophotometric assay (Beutler 1980),Other quantitative methods,Semi-quantitative methods. (Cytofluorometry to quantify the number of G6PD sufficient and G6PD deficient cells. The test is quantitative for the number of cells and semi quantitative for the G6PD activity. The test is applied to check for skewing in heterozygous females.)
