This test is Medicare rebatable provided the patient signs the Medicare assaignment on the consent form. Please note that samples are referred interstate for testing. An FBE must be co-requested with these metabolites. Sample insurance correspondence for PROMETHEUS ® Thiopurine Metabolites. These tests have not been cleared or approved by the US FDA. The tests are used for clinical purposes and should not be regarded as investigational or for research.
Thiopurine metabolite concentrations are identified to assess therapeutic and toxic concentrations. If thiopurine therapy has not been initiated, order Thiopurine Methyltransferase, RBC (0092066). 2016-08-29 · THIOPURINE METABOLISM The prodrug AZA is converted non-enzymatically by biogenic thiols, including glutathione, to MP with the release of methyl-4-nitro-5-imidazole. Following uptake by transporters, MP undergoes metabolism by three compet-ing pathways (see figure 1) to form the active metabolite, thioguanine nucleo-tides (TGNs) which function 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.

Red blood cell (RBC) count is first performed and then the thiopurine metabolites' values are determined by liquid chromatography-tandem mass spectrometry (LC-MS/MS). Values are utilized to calculate and report a final result (unit of measure: pmol/8 x 10 RBC) for 6-thioguanine nucleotides and 6-methylmercaptopurine derivative analyte.

Clinical Significance Thiopurine Metabolites - 6-Mercaptopurine (Purinethol) and its imidazolyl derivative, Azathioprine (Imuran), are immunosuppressive drugs. 6-Mercaptopurine (6-MP) is indicated for remission induction and maintenance therapy of acute lymphoblastic leukemia (ALL). Background: Thiopurine use in inflammatory bowel disease (IBD) is limited by drug toxicity and lack of therapeutic efficacy.

This test is primarily used to verify compliance, optimize therapy, and identify elevated metabolite concentrations that may result in toxicity after initiation of thiopurine drug therapy for the treatment of inflammatory bowel disease.
Thiopurine drug metabolism and risk for adverse reactions to thiopurines may be affected by genetic and nongenetic factors that are not evaluated by this test Test does not assess for TPMT allele variants associated with ultrahigh enzyme activity Genotyping does not replace the need for therapeutic drug monitoring and clinical observation Phenotype test used to optimize therapy for patients who are taking thiopurine drugs.
