    Abstract:
    OBJECTIVE: To screen rare blood groups Fy(a-), s-, k-, Di(b-) and Js(b-) in an ethnic Zhuang population. METHODS: Sequence-specific primers were designed based on single nucleotide polymorphism (SNP) sites of blood group antigens Fy(b) and s. A specific multiplex PCR system I was established. Multiplex PCR system II was applied to detect alleles antigens Di(b), k, Js(b)1910 and Js(b) 2019 at the same time. The two systems was were used to screen for rare blood group antigens in 4490 randomly selected healthy donors of Guangxi Zhuang ethnic origin. RESULTS: We successfully made the multiplex PCR system I. We detected the rare blood group antigens using the two PCR system. There are five Fy(a-), three s(-), two Di(b-) in 4490 Guangxi zhuang random samples. The multiplex PCR system I has achieved good accuracy and stability. With multiplex PCR systems I and II, 4490 samples were screened. Five Fy(a-), three s(-) and two Di(b-) samples were discovered. CONCLUSION: Multiplex PCR is an effective methods, which can be used for high throughput screening of rare blood groups. The rare blood types of Guangxi Zhuang ethnic origin obtained through the screening can provide valuable information for compatible blood transfusion. Through screening we obtained precious rare blood type materials which can be used to improve the capability of compatible infusion and reduce the transfusion reactions.
