A tacrolimus blood test is used to monitor the drug levels in a patient's bloodstream to ensure it's within a therapeutic range, especially after organ transplantation.
What is the principle of tacrolimus test?
The test measures the concentration of tacrolimus in the blood using immunoassays or mass spectrometry, providing insights into drug efficacy and potential toxicity.
What are the methods of tacrolimus test?
The methods include immunoassays (e.g., enzyme-linked immunosorbent assay) and mass spectrometry (e.g., LC-MS/MS), offering varying levels of precision and sensitivity.
What is a normal tacrolimus level?
Normal levels vary by transplant type, but therapeutic ranges typically aim for 5-15 ng/mL in the first few months and 3-10 ng/mL later for kidney transplant recipients.
