Immunogenetics/HLA Laboratory Profiles

When a kidney transplant candidate has a medically-suitable potential living donor(s) ( it can be a willing family member(s) or friend(s)) a series of tests are performed to determine compatibility.

The patient and potential donor(s) should be scheduled for initial testing.

The donor(s) is/are ABO-typed to confirm compatibility to the patient.  If compatible, the patient’s serum is crossmatched with lymphocytes from the potential donor(s) and from the patient. If the crossmatch is negative, then the donor(s) is/are HLA-typed.

Recipient Tests Ordered:

Donor(s) Tests Ordered:

  • ABO & Rh typing (for new donors only)
  • Solid Organ Donor ABO & Rh (includes A1 lectin if group A)
  • HLA Class I + II (A,B,C,DR,DQ) Typing (test run only if lymphocyte crossmatch is negative or per request of transplant center)

 

Initial Evaluation of Recipient and Donor for a Donor Exchange

The recipient typically has either ABO-incompatible or crossmatch-positive living donor(s); no additional testing required for the recipient at initial evaluation.

Donor(s) Tests Ordered:
