About this test
The Tacrolimus test measures drug levels in the blood to monitor therapy and prevent organ transplant rejection.
The Tacrolimus blood test measures the level of immunosuppressant medication in your body, primarily after organ transplantation (kidney, liver, heart) to prevent rejection while avoiding toxicity.

Maintaining appropriate tacrolimus levels is critical. Low levels may increase the risk of transplant rejection, while high levels can cause toxicity, including kidney damage and increased susceptibility to infections.

This test is routinely used in transplant patients to monitor drug levels, adjust dosage, and ensure effective and safe immunosuppressive therapy. It is also helpful in assessing compliance and detecting potential drug interactions.

The purpose of this test is to

  • To measure tacrolimus levels in the blood
  • To monitor immunosuppressive therapy
  • To ensure safe and effective dosing
  • To detect drug toxicity
  • To assess treatment compliance
