What is Thiopurine Methyltransferase (TPMT) Enzyme Activity?

The Thiopurine Methyltransferase (TPMT) enzyme activity test measures how well your body processes certain medications called thiopurines. These drugs are used to treat conditions like autoimmune diseases and some cancers.

Why is this test important?

Measuring TPMT activity is crucial before starting thiopurine medications, as low activity can lead to severe side effects due to drug accumulation. This test helps doctors determine the safest and most effective dose for you, minimizing risks.
