What does a donor pre-evaluation entail?

Match and health. Tissue match is certainly needed for donation to make sure the recepient will not reject. Also, the health of the donor is evaluated to make sure the donor will not be hurt by donating his kidney. Also, a final stage is evaluation of the anatomy of blood vessels that will be operated upon. Along the way, a psychosocial eval makes sure the donor is actually interested & not pressured to donate.
Being healthy. I am assuming for Renal transplant.
The donor should be match(as far as blood type). Should be absolutely healthy, no Hypertension or diabetes or proteinuria .
