The purpose of this pilot study is to determine if there is clinical correlation between the
CKT and transplant recipients who are known to be on minimal or no immunosuppression
(presumed tolerant) and those who are on conventional amounts of immunosuppression and have
either experienced rejection (presumed hyper-responsive to donor) or have not experienced
rejection (unknown responsive state).
- Kidney or liver transplant recipients for whom donor cells are available
- HcT <32%
