RESUMEN
Objective To investigate the influence of bloody cervical cell samples on human papillomavirus(HPV) genotyping detection using flowcytometry fluorescence hybridization kit.Methods According to the concentration of hemoglobin(Hb),cervical cell samples were divided into five groups,including group A with Hb of 0 g/L(10 cases),group B with 0 g/L100 g/L.In each group,50% samples were with initial positive results of HPV genotyping detection.Every sample was detected using sample volume of 50,100,200,500 and 1 000 μL different volumes for testing and analysis results.Results For all samples with initial negative results,five samples with initial positive results in group A and five samples with initial positive results,the detected results of different sample volume were without differences.In the 10 samples,with initial positive results of group C,D and E,there were four,four and nine samples respectively,were with false negative detected results of different sample volumes.Conclusion Bloody cervical cell samples could cause false negative results of HPV genotyping detection using flowcytometry fluorescence hybridization kit.It might be necessary to set optimal sample volume according to the concentration of Hb for ensuring the accuracy of genotyping detection.
