When does a doctor order TPMT (Thio Purine Methyl Transferase) Gene?

TPMT (Thio Purine Methyl Transferase) Gene is usually offered as part of a pharmacogenetic panel before starting thiopurine drugs used in cancer, inflammatory bowel disease, or autoimmune conditions. Your doctor may order it if you had severe blood count drops or unexpected side effects from these medicines.

Who should get TPMT (Thio Purine Methyl Transferase) Gene done in Lucknow?

Lucknow's growing population, rich Awadhi diet driving diabetes and heart disease, winter air pollution, and seasonal monsoon infections make regular preventive diagnostic testing worthwhile for residents across the city. Blood-count testing benefits anyone with fatigue, pallor, or frequent infections, menstruating and pregnant women prone to anaemia, and patients on medication that affects the bone marrow. In Lucknow, iron and B12 deficiency anaemia are common, particularly among women and those on vegetarian diets in Chowk, Telibagh, and surrounding areas.

What conditions can TPMT (Thio Purine Methyl Transferase) Gene help diagnose?

Genetic variants cause low or absent enzyme function, increasing toxicity risk. A family history of thiopurine sensitivity also supports testing.

What do TPMT (Thio Purine Methyl Transferase) Gene results mean?

Higher or positive results: High TPMT activity means your body rapidly inactivates thiopurine drugs (azathioprine, 6‑mercaptopurine). Lower or negative results: TPMT deficiency reduces metabolism of thiopurine drugs, causing buildup of toxic metabolites that often lead to severe bone marrow suppression (pancytopenia: leukopenia, anemia, thrombocytopenia), increasing infection and bleeding risk. Your doctor reads the value against the reference range on your report and your symptoms, and may repeat a borderline result to confirm it.

How often should TPMT (Thio Purine Methyl Transferase) Gene be repeated?

Healthy adults: as part of an annual health check. Patients with anaemia under treatment: every 4 to 12 weeks until corrected. Patients on chemotherapy or marrow-affecting drugs: as frequently as their specialist directs, sometimes weekly. Pre-surgical patients: as part of standard clearance.

What happens after TPMT (Thio Purine Methyl Transferase) Gene results are ready?
