Result Interpretation

Tacrolimus testing is performed on the Abbott Architect by chemiluminescent microparticle immunoassay. The therapeutic range of tacrolimus is not clearly defined but target 12-hour trough whole blood concentrations are 5.0-20.0 ng/mL early post transplant. Twenty-four hour trough concentrations are 33%-50% less than the corresponding 12-hour trough.
