Test Overview
Trinity Biotech Qualitative Screening Kit-using long wave UV light
Check for G-6-PD deficiency in patients with unexplained episodes of hemolysis. Screen certain ethnic groups who may be given drugs that would produce hemolytic crises.
Normal by fluorescent screen
* Reference ranges may change over time. Please refer to the original patient report when evaluating results.
This procedure can only differentiate between normal and grossly deficient samples. A G6PD blood enzyme screen performed after a hemolytic episode often will not detect G6PD deficiency, even if present, because the most deficient cells have been destroyed. Likewise, patients with high reticulocyte counts and/or those who are status post red blood cell transfusion may appear G6PD normal, masking a deficiency state.
