Dear visitor,

A plasma level test is performed after stopping treatment with Leflunomide medac and following a washout procedure. The plasma level test is used to check whether the active substance has been sufficiently removed from the body. This will be confirmed by two blood tests at an interval of at least 14 days.

If you wish further information on the plasma level test, please contact us by phone at
