Comparison between HC2 and PCR-RDB for detecting HPV infection in women

Objective To compare hybrid capture-Ⅱ(HC2) to polymerase chain reaction (PCR)-reverse dot-blot(RDB) for detecting HPV infection in women.Methods HC2 method and PCR-RDB were applied to detecting human papillomaviral infection in female genital duct,and the test results were analyzed.Results Concordant results were found in 81.14%(400/493) samples(Kappa =0.63;95%CI,0.57-0.69).The high risk type HPV positive rate detected by PCR-RDB were 1.60%(3/187),29.85%(20/67),69.88%(58/83),86.52%(77/89) and 91.04%(61/67),respectively, when the HC2 RLU/CO of samples were1.00,1.00-9.99,10.00-99.99,100.00- 999.99 and≥1 000.00.Statistical differences were found among the five groups(x~2=289.3,P0.01).Cross reactions were found between HC2 high risk probe and HPV53,66,11,cp8304 and other genotypes.Conclusion There is good concordance between HC2 and PCR-RDB,though cross reaction exists in HC2.Relatively speaking,there are more influential factors for PCR-RDB.
