The purpose of this study is to determine the rate of successful blood collection using FDA approved patient self-collection devices.
The objectives of this study are to compare PSA mesurements and the measured tacrolimus concentrations in patient self-collected capillary whole-blood compared to venipuncture obtained whole-blood, to establish the rate of quantity not sufficient (QNS), clotting, or other pre-enalytical fails using patient self-collected capillary whole-blood, and to gauge the patient perspective on self-collection versus venipunture for comfort and convenience.
