WebCode: U548. Test Overview : Thiopurine S-Methyltransferase (TPMT) is an enzyme that catalyzes the S-Methylation of thiopurine drugs such as 6-mercaptopurine (6-MP), 6-thioguanine (6-TG) and azathioprine. These drugs are often used for treatment of childhood leukemia, inflammatory bowel disease and organ transplantation. WebAn apparent genetic polymorphism has been observed in TPMT activity among white and black populations, with low TPMT levels noted in 0.3% of individuals and intermediate …
Cell Subset-Specific Chimerism Testing by Short Tandem
WebThe blood sample is sent to the laboratory and DNA is purified from your blood sample. Your DNA is analyzed to look for mutations in selected regions of the TPMT gene. Limitations of the test — This test analyzes selected regions of the TPMT gene where the vast majority of the mutations causing TPMT deficiency are located. dragonspine bow genshin
