Refer to Specimen stability criteria as shown below
Ambient
72 hours
Refrigerated
7 days
Frozen
14 days
Unacceptable Conditions
Specimens that exceed stated stability, unlabeled/mislabeled/mismatched specimens, specimens submitted in leaking containers
Special Instructions
This test requires its own lavender top. Collecting sample just before the next dose will be adequate for monitoring purposes. Optimal response to Tacrolimus is usually associated with the trough blood concentration (i.e., the minimum concentration experienced just before the next dose).
