Patterns of volunteerism, testing, and exclusion among potential living kidney donors

We found that in kidney transplantation, more females donate. We analyzed transplant recipients for patterns of potential donor exclusion and found that equal proportions of male and female potential donors existed among first-degree biological relatives. More male recipients were married and therefore had more spousal potential donors. Among friends and non-first-degree relatives, significantly fewer males offered to donate to females. Equal proportions of female and male potential donors were excluded from donating for medical comorbidities, blood type incompatibility, recipient refusal, and potential donor reluctance. We concluded that female transplant candidates had fewer potential donors among spouses and opposite sex volunteers from friends and non-first-degree relatives.
