Immune Cell Function Assay

DESCRIPTION

The immune cell function assay measures the concentration of adenosine triphosphate (ATP) in whole blood and has been proposed as a method to monitor immunosuppression parameters in individuals with solid organ and hematopoietic stem cell transplants. Careful monitoring of lifelong immunosuppression is required to balance the dual risks of rejection and infection. Currently, immunosuppression levels are determined by testing for clinical toxicity (e.g., leukopenia, renal failure) and by therapeutic drug monitoring.

Immune cell function assays (i.e., ImmuKnow®, Pleximmune™) have been cleared for marketing by the FDA; however,the predictive characteristics of the test are still uncertain and the evidence is insufficient to determine the effects of the technology on health outcomes.

POLICY  

IMPORTANT REMINDER

ADDITIONAL INFORMATION

The clinical utility of immune cell function assays to impact net health outcome in comparison to current methods of care for transplant recipients has not been evaluated.
