DNA methods have resulted in improved renal allograft survival rates in cadaveric renal transplantation. This paper describes the impact of DNA typing by PCRSSP on a living related renal transplant (LRRT) programme. It evaluates error rates in serology, acute rejections, graft function and survival rates between the two typing methods. Serological typing was done on CTS 120 antisera Class 1 and 60 antisera Class 2 and 72 antisera Terasaki Class1 and 72 antisera Class2 Antigens. Low resolution PCR-SSP typing was done by 24 primers for HLA A , 48 for HLA B and 24 for HLA DR. Of the 585 transplants, 159 (Group I) were serology based, 172 serology and PCR-SSP for HLA DR (Group II) and 254 on serology and PCR-SSP for HLA A and B and only PCR-SSP for HLA DR (Group III). Error rates in serology as compared to PCR-SSP were 24% for HLA A, 16% for HLA B and 35% for HLA DR. Acute rejection in Group I were 39% Group II 30% and Group III 26% (p 0.02). Graft function of serum creatinine<1.5 mg/dl at 1 year was found in 26% of Group I patients as compared to 48% of Group III (p<0.0001). One and three year graft survival was 93% and 87% for Group II as compared to 81% and 69% for Group I respectively (p 0.0001). Matching by this combination of serology and PCR-SSP is not only economical for a developing country but also improves graft survival by 12% at 1 and 18% at 3 years.
