We are presenting the immunologic pattern of 100 patients with kidney transplant made from 1990-2000 at CHM CSS Dr.AAM. Eighty nine were alive related donors. Most of them were from blood group O, donors and receptors. They came from Panama, Chiriqui and Colon. Many of the donors were siblings. The grades of compatibility in frequency were D, C, A & B. For locus HLA-A the most common gen was A2 for transplanted patients and for the rest of the Panamanian population is A24. For the locus HLA-B were B35 and B38 respectively and for the locus HLA-C the most common gen was C4, and C3 for the rest of the population.
