Optimize drug concentrations by measuring drug metabolites. For clinicians considering thiopurine drug therapy, ARUP offers a full menu of testing to support patient care. test code test name 0092066 Thiopurine Methyltransferase, RBC •Phenotype test that assesses risk for severe bone Thiopurine methyltransferase (TPMT) deficiency is a condition in which patients treated with standard doses of azathioprine (AZA, Imuran), 6-mercaptopurine (6-MP, Purinethol), or 6-thioguanine (6-TG, Thioguanine Tabloid) may develop life-threatening myelosuppression or severe hematopoietic toxicity. For thiopurine methyltransferase (TPMT) enzyme activity testing, order TPMT3 / Thiopurine Methyltransferase (TPMT) Activity Profile, Erythrocytes.

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.

2019-07-26 · The Thiopurine S-Methyltransferase Blood Test is a blood test to assess the activity or production potential of TPMT in an individual. It is done to indirectly determine thiopurine drug sensitivity TPMT enzyme activity is often measured from red blood cells. La thiopurine S-méthyltranférase (TPMT) est une enzyme qui assure le catabolisme des thiopurines (azothioprine, 6-mercaptopurine, thioguanine) qui inhibent le système immunitaire et qui sont utilisées dans le traitement de certaines pathologies malignes hématologiques, de maladies auto-immunes (maladie de Crohn, polyarthrite rhumatoïde), et après transplantation d'organe.

Thiopurine S-methyltransferase deficiency patients have a mutation in either one or both copies of the TPMT gene that causes reduced enzyme activity and difficulties breaking down thiopurine drugs.

N.B. TPMT activity 10 – 19 mU/L may be seen in TPMT deficient patients who have been transfused. 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.

Thiopurine methyltransferase (TPMT) deficiency is a condition in which patients treated with standard doses of the immunosuppressant azathioprine or the antineoplastic drug 6-mercaptopurine (6-MP) may develop life-threatening myelosuppression or severe hematopoietic toxicity.

Abnormal TPMT activity: 25 U/mL - Individuals are predicted to be at high risk of bone marrow toxicity as a consequence of standard thiopurine dosing; a dose reduction and therapeutic monitoring is recommended.
