Size Estimation of HLA -Ⅰ class Typed Platelet Apheresis Donor Bank / 中国实验血液学杂志

ABSTRACT

OBJECTIVE@#To estimate the size of HLA -Ⅰ class typed platelet apheresis donor bank.@*METHODS@#A total of 16062 blood samples from Chinese Han voluntary unrelated marrow donors in Jiangsu were included in this study. Luminex-SSO was used to detect the HLA -Ⅰ class(A,B locus) antigens. The probability of finding at least one HLA matched unrelated donor was calculated based on the HLA -I class phenotype frequency.@*RESULTS@#The population genetic data of HLA -Ⅰ class in Jiangsu were obtained, the optinal bans size in HLA typed apheresis plateler donor registry databane hrad been estimated by evaluating the population genetic data of HLA-1 class same donor.@*CONCLUSION@#The establishment of HLA-1 class typed apheresis platelet donor bank with a total size of 1500 persons is acceptable, which can satisty the patients with phenotype freguency>0.002 to find at least 1 phenotype same donor in 95% probavility.
