Analytical performance of RNA isolated from BD SurePath™ cervical cytology specimens by the PreTect™ HPV-Proofer assay.

Several commercial HPV ancillary tests are available for detection of E6/E7 RNA. It is not clear how storage of a cervical Pap affects the analytical and clinical performance of the PreTect™ HPV-Proofer assay. To investigate the qualitative performance of RNA extracted from BD SurePath™ liquid-based cytology (LBC) specimens for the detection of human papillomavirus (HPV) E6/E7 mRNA using the PreTect™ HPV-Proofer assay, studies including stability, reproducibility, residual specimen analysis, and storage medium comparison assays were performed.

Recovery of DNA from BD SurePath cytology specimens and compatibility with the Roche AMPLICOR Human Papillomavirus (HPV) Test.

Background: The AMPLICOR HPV Test has been validated for use with cervical cells collected in liquid-based preservative fluids, such as BD SurePath. It is currently recommended, however, that residual BD SurePath samples be stored at 4 degrees C prior to testing.

Objectives: The aim of this study was to demonstrate that DNA isolated from SurePath cervical cytology specimens and stored at ambient temperature was also compatible with the AMPLICOR HPV Test.
