Specimen Required. Patient Preparation: Thiopurine methyltransferase (TPMT) enzyme activity can be inhibited by several drugs and may contribute to falsely low results. Patients should abstain from the following drugs for at least 48 hours prior to TPMT testing: naproxen (Aleve), ibuprofen (Advil, Motrin), ketoprofen (Orudis), furosemide (Lasix), sulfasalazine (Azulfidine), mesalamine (Asacol

This test identifies patients who, due to genetic variation, have undetect- able TPMT activity and if treated with thiopurine drugs such as azathioprine experience

The drugs involved 25 Jan 2007 TPMT enzyme measurement is based on the red cell activity levels, which can be distorted following blood transfusion. Up to 10% of inflammatory Thiopurine interaction with ASAs, benzoic acid derivatives, non-steroidal anti- inflammatory drugs, and methotrexate have been shown to influence TPMT enzyme This test identifies patients who, due to genetic variation, have undetect- able TPMT activity and if treated with thiopurine drugs such as azathioprine experience 12 Mar 2021 Assessing TPMT prior to the initiation of thiopurine drugs is recommended. 1-3 TPMT activity is measured in red blood cells. TPMT enzyme The tests for thiopurine methyltransferase (TPMT) enzyme activity or its underlying genetics are measured in people who are about to start treatment with a 15 Jan 2006 Thiopurine methyltransferase in acute lymphoblastic leukemia.

Thiopurine methyltransferase test

Thiopurine S-Methyltransferase (TPMT) Genotype - Thiopurine S-methyltransferase (TPMT; S-adenosyl-L-methionine:thiopurine S-methyltransferase) catalyzes thiopurine S-methylation, an important metabolic pathway for antineoplastic and immunosuppressive drugs. MSD and the MSD Manuals. Merck & Co., Inc., Kenilworth, NJ, USA (known as MSD outside of the US and Canada) is a global healthcare leader working to help the world be well. Back to Test Catalogue Thiopurine Methyltransferase (TPMT) Genotype, Blood. Test ID: TPMTGENO.

Clin Pharmacol Ther. 2011 Mar; 89(3):387-391.

Phenotypic test that provides a quantitative measurement of TPMT enzyme activity levels to assist physicians with azathioprine (Imuran) or 6-MP (Purinethol) dosing strategies. Individuals with low thiopurine methyltransferase are at risk of excessive myelosuppression.

Changes in the TPMT gene cause TPMT deficiency, which is a reduction in the activity of the TPMT enzyme. Without enough of this enzyme, the body cannot "turn off" thiopurine drugs by metabolizing them into inactive compounds. Test Code TPMTA Thiopurine Methyltransferase, RBC Clinical Indications Phenotype test to assess risk for severe myelosuppression with standard dosing of thiopurine drugs.

Test Code LAB4945/10671/TPNUV Thiopurine Methyltransferase (TPMT) and Nudix Hydrolase (NUDT15) Genotyping, Varies Advisory Information For thiopurine methyltransferase (TPMT) enzyme activity testing, order TPMT3 / Thiopurine Methyltransferase (TPMT) Activity Profile, Erythrocytes.

Prometheus Biosciences is certified under the Clinical Laboratory Improvement Amendments (CLIA) as qualified to perform high-complexity clinical laboratory testing and is accredited by the College of American Pathologists (CAP). Uses for Test • Identify patients who are at risk for abnormal drug metabolism and toxicity from thiopurine drugs metabolized by thiopurine S-methyltransferase (TPMT), including azathioprine, 6-mercaptopurine, and thioguanine. • Identify genotypes shown to have a drug-gene variant relationship.
