[Investigation on HPV DNA detection and genotyping practices used in French laboratories in 2009].

The French National reference Laboratory for Human papillomavirus (HPV) performed in 2009 a national study in order to review the methods used to detect and identify HR HPV genotypes in microbiology laboratories. Results from this study show a great diversity in volumes of samples treated in laboratories. Among clinical indications, the most frequent is a result of ASC-US at a Pap smear. This indication in the only one covered by the National Public Insurance System and is mostly performed in laboratories from private sector. Other indications mainly correspond to research programs and are performed in public Hospitals. This study allowed also to review the adequacy between the liquid based cytology samples and the assays used for direct detection of HR HPV or identification of the genotypes present in the sample. The right tests were not carried in the right solution storage according to the recommendations from different HPV testing assays. National recommendations should be elaborated in order to improve the performance of the test used.
