The purpose of this study is to assess relationship between tacrolimus concentrations determined via whole blood MITRA assay method with those determined using the established and validated whole blood venepuncture method using samples taken from liver and kidney transplant participants.
This will be a bioanalytical assay method cross-validation study using blood samples donated by liver or kidney transplant participants. Participants will have been on a stable dose of Advagraf and deemed clinically stable for a period of 3-6 months and attend a routine out-patient follow-up visit to receive their usual oral dose of commercial Advagraf. Participants will be asked to provide 1 whole blood venepuncture sample and 1 whole blood finger prick MITRA sample at pre-dose and at approximately 1 and 3 hours post-dose. Participants will be kept at the study site for an extra 1 hour to ensure post-sampling safety and will be discharged thereafter.

Comparison of blood concentrations of tacrolimus
Tacrolimus concentrations will be determined from the dried whole blood samples collected via finger prick into MITRA cartridge and in whole blood taken by venipuncture.
