Glucose-6-Phosphate Dehydrogenase (G6PD) Deficiency Screen
Department of Haematology
Notes
- Quantitation performed at Bristol Royal Infirmary
- See also: Pyruvate Kinase Deficiency
Sample Requirements
2ml or 4ml EDTA sample, paediatric 1mL EDTA sample
Turnaround Times
Quantitation: 1-2 weeks
Reference Range
| Range | Units | |
| G6PD Quantitation | 4.6 - 13.5 | U / g Hb |
Time limit for add ons
5 days (if sample has been refrigerated)
Minimum retesting interval
Tests should not normally be repeated. If the original sample has been taken during active haemolysis suggest repeating after resolution of haemolytic episode.
Interfering substances
High WBC and high platelet counts can interfere with the method and cause higher than normal levels of G6PD. Reticulocytes have higher than normal G6PD so a false normal result may be obtained from individuals with a reticulocytosis. Please send a sample for repeat testing after resolution of a reticulocytosis."
