Glucose-6-Phosphate Dehydrogenase (G6PD) Full Gene Sequencing, Varies
Use
This test is used for genetic testing of individuals at high risk for glucose-6-phosphate dehydrogenase (G6PD) deficiency. It aids in diagnosing G6PD deficiency, determining G6PD deficiency status in individuals with inconclusive or unexpected phenotyping results, differentiating heterozygotes with skewed X-inactivation from homozygotes and compound heterozygotes, and making a definitive diagnosis of carrier status. Additionally, it is useful in evaluating neonates with unexplained jaundice and identifying individuals at risk for drug-induced acute hemolytic anemia related to G6PD deficiency.
Special Instructions
Not provided.
Limitations
This test involves full gene sequencing of all exons and exon/intron boundaries of the G6PD gene. It does not assess glucose-6-phosphate dehydrogenase enzyme activity. False negatives may occur if a mutation is outside the regions sequenced.
