Test Includes: 6 -thioguanine (6 TGN) and 6 methylmercaptopurine (6 MMPN) reported in pmol/8x10(8)RBC. Logistics Test Indications: Provides red blood cell (RBC) levels of 6 -thioguanine (6 TG) and 6 methyl-mercaptopurine (6-MMP). These target levels help monitor a patient’s metabolism of thiopurine drug therapy.

thiopurine metabolism, the importance of thiopurine S-methyltransferase testing prior to the start of therapy and the monitoring of thioguanine nucleotide levels while on treatment, guiding a personalised approach to optimising thiopurine therapy.

Testing prior to the initiation of therapy enables clinicians to detect individuals with low thiopurine methyltransferase (TPMT) activity who are at risk for excessive myelosuppression or severe hematopoietic toxicity when taking thiopurine drugs. Prometheus Laboratories Inc. partnered with Medco Research Institute LLC to evaluate the clinical- and cost-effectiveness of Prometheus' Thiopurine Metabolites test ing when used to optimize the dosing of thiopurines for inflammatory bowel disease (IBD). 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).

An additional way of further optimizing dosage is by measuring circulating thiopurine metabolite concentrations. However, the use of metabolites in clinical practice is controversial. 3 , 4 The aim of measuring thiopurine metabolite concentrations in IBD patients is to optimize thiopurine therapy, ensuring maximal therapeutic effect with minimization of the risks of adverse effects.

Values are utilized to calculate and report a final result (unit of measure: pmol/8 x 10[8] RBC) for 6-thioguanine nucleotides and 6-methylmercaptopurine derivative analyte. A doctor may order a blood test for thiopurine metabolites to monitor drug therapy. Measuring the metabolites is another way to ensure that toxic levels do not build up in the blood.

Clinical Biochemistry, City Hospital Birmingham. Specimen Type: 4ml EDTA. Storage: 4oC prior to posting. 26 Aug 2014 Guidelines assist practitioners with decisions regarding testing and levels or TPMT testing and thiopurine metabolites were categorized as 10 Apr 2019 metabolite testing for those on thiopurine therapy. The tests are referred to as.

Values are utilized to calculate and report a final result (unit of measure: pmol/8 x 10[8] RBC) for 6-thioguanine nucleotides and 6-methylmercaptopurine derivative analyte. Background & Aims.

This test helps identify individuals at increased risk of hepatotoxicity from thiopurine dose escalation. Patients with a TMPT activity of 4-12 nmol 6-MMP/hr/mL RBC (heterozygote/low metabolizer) are at increased risk and may require a lower dose of thiopurine … Test Code THIO Thiopurine Metabolites, Whole Blood Shipping Instructions.
