Evaluation of the Tasso+ blood self-collection device for quantitation of plasma cytomegalovirus (CMV) DNAemia in adult solid organ transplant recipients (SOTr).

We evaluate an FDA-cleared blood self-collection device (Tasso+) and demonstrate that it is patient-acceptable and yields a liquid blood sample with quantitative CMV DNAemia results comparable to those of standard venipuncture samples. This opens up possibilities for self-blood collection to monitor for CMV and potentially other viruses in transplant and other at-risk populations.
