Abstract:
Objective To evaluated the HCV genotyping results which obtained by genotype diagnostic kit in Shenzhen area. Methods 158 samples which ELISA test of anti-HCV were positive were collected from voluntary blood donors from 2014 to 2015,and were tested by PCR fluorescence probe method for viral load.The samples which viral load were greater than 1.0 ×103 IU/mL were then tested by HCV RNA genotype diagnostic kit.To analysis the proportion of different genotypes and the correla-tion between genotypes with vrial load.Results 54 HCV RNA reactive sample were quantity by PCR fluorescence probe method from 158 anti-HCV positive samples.The genotyping data for 45 cases which vrial load greater than 1.0×103 IU/mL were obtained by HCV RNA genotype diagnostic kit.The frequencies HCV genotype 1b,2,3 and 6 were 57.78%(26/45),6.67%(3/45),8.89%(4/45)and 26.67%(12/45),respectively.One-way ANOVA analysis showed that significant difference in viral loads was found be-tween different HCV genotype 1b and 2(F =2.861,P <0.05),and there was a significant difference in viral loads and anti-HCV S/CO by sex(P <0.05).Fisher′s exact test showed the significance difference between age and genotypes(P <0.05 ).Conclusion HCV 1b and 6 were the most predominant genotypes due to the higher viral load than the other subtypes among volunteer blood do-nors in Shenzhen,while the proportion of HCV 2,3 declined.
