The tacrolimus test is ordered to measure the amount of drug in the blood.
Measurement of tacrolimus blood levels may be of use in monitoring patients receiving this drug. Specimens from patients who have circulating human antimouse (HAMA) as a result of having received mouse monoclonal antibodies may give falsely elevated or depressed results in this assay.

How our test process works!
Overview:
- Purpose: Ensures tacrolimus levels are within a therapeutic range to prevent organ rejection and avoid side effects.
- Use Cases: Commonly used for patients with liver, kidney, heart, or lung transplants.
Risk Assessment:
- Too Low Levels: Risk of organ rejection due to insufficient immunosuppression.
- Too High Levels: Risk of toxicity, leading to adverse effects such as kidney damage, neurological symptoms, and increased infection risk.
Normal Range:
- The normal therapeutic range is typically 5-20 ng/mL, but it can vary based on individual factors, transplant type, and time since transplantation.
- Exact target range should be set by the healthcare provider.
Interpretation:
- Below Normal Range: May indicate inadequate dosing or rapid metabolism, increasing the risk of rejection.
- Within Normal Range: Suggests effective dosing with a balance between immunosuppression and toxicity risk.
- Above Normal Range: Indicates possible toxicity, requiring a dosage reduction or closer monitoring.
Sample Type:
- Whole Blood Sample: Typically drawn in a lavender (EDTA) tube.
- Timing: Blood is usually drawn 12 hours after the last dose or immediately before the next dose (trough level) for consistent monitoring.
