Summary
Cytochemical staining effectively identifies females with glucose-6-phosphate dehydrogenase (G6PD) deficiency, crucial for predicting hemolytic anemia risk. This method assesses red blood cell enzyme activity for safer drug and oxidant exposure management.
Area of Science:
- Biochemistry
- Genetics
- Hematology
Background:
- Glucose-6-phosphate dehydrogenase (G6PD) deficiency is a common X-linked genetic disorder.
- Certain G6PD alleles lead to low enzyme activity in red blood cells, increasing hemolysis risk with oxidative stress.
- Heterozygous females have two red blood cell populations with distinct G6PD enzyme characteristics.
