DNA Genetic Tests: HLA-B*1502 Detection
Many studies have demonstrated the strong association of Human Leukocyte Antigen (HLA*B1502) and carbamazepine, phenytoin, & oxcarbazepine induced Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN). Individuals that use DNA tests to determine their HLA genotypes prior to taking these drugs can reduce their risks of developing SJS/TEN by as high as 1300 times. |
