Q

Goals of pretransplant screening

A
  1. To identify conditions which may disqualify either donor or recipient
  2. To identify and treat active infection pretransplant
  3. To define the risk of infection and determine strategies for preventing and mitigating posttransplant infection
  4. To implement preventative interventions
  5. To facilitate transplants from previously infected donors and recipients.
