ORGAN DONATION AND SCREENING Flashcards
Goals of pretransplant screening
- To identify conditions which may disqualify either donor or recipient
- To identify and treat active infection pretransplant
- To define the risk of infection and determine strategies for preventing and mitigating posttransplant infection
- To implement preventative interventions
- To facilitate transplants from previously infected donors and recipients.

There are two types of serologic tests for syphilis:
what are those
non treponemal tests
treponemal-specific tests.
a type of serologic test for syphilis that detect antibodies against cardiolipin
and are not specific.
Non-treponemal tests
a type of serologic test for syphilis that detect antibodies against specific
treponemal antigens.
Treponemal tests
