For clinicians considering thiopurine drug therapy, ARUP offers a full menu Thiopurine drug therapy is used for autoimmune diseases, inflammatory bowel disease, acute lymphoblastic leukemia, and to prevent rejection after solid organ transplant. The inactivation of thiopurine drugs is catalyzed in part by thiopurine methyltrasferase … The TPMT blood test is used to test the activity of the thiopurine methyltransferase enzyme. Sometimes the test is ordered to measure the genetic structures that are in place supporting the TPMT activity instead. There are two primary reasons for having this test ordered. 1.To determine if starting treatment with a thiopurine drug is suitable.

( RBC) Sunquest Code: TPMT. Epic Code: LAB6987, Epic Name: Thiopurine Methyltransferase, RBC. Synonyms: Thiopurine Methyltransferase (TPMT) Enzyme Activity Thiopurine methyltransferase or thiopurine S-methyltransferase (TPMT) is an enzyme that in humans is encoded by the TPMT gene. A pseudogene for this locus To evaluate this assay, we compared it with conventional TPMT phenotyping, which uses a red blood cell (RBC) lysate and genotyping for analysis of common Distinct inheritable differences in levels of red blood cell TPMT have been detected among patients. Patients with low or absent TPMT activity metabolize the drugs Jan 9, 2002 Although studies have been confined to measurements of TPMT activity in RBC, determined by radiochemical assays based on the original Objective: Long-term (13 weeks) and circadian (24 hours) intraindividual variability in red blood cell (RBC) thiopurine methyltransferase (TPMT) activity in Alternatives to TPMT genotyping are available and include testing TPMT TPMT activity (phenotype) can be measured directly in red blood cell membranes.
