Study Arms:
- retrospective (Type: EXPERIMENTAL): archived specimens from blood donors whose units have already been released and transfused into recipients will be tested. Attempts will be made to contact and obtain follow up specimens from both the donor and recipient of units initially testing positive for B.microti. the interventions are investigational diagnostic tests for B.microti (PCR and IFA).
- prospective, real time (Type: EXPERIMENTAL): specimens from current blood donors will be tested and those testing positive for B.microti will not be released and the units will be disgarded, and the donors notified and deferred from future blood donation. the interventions are investigational diagnostic tests for B.microti (PCR and IFA).

Based on this trial design, predict the completion outcome and termination type (if applicable).
