BACKGROUND: Human papillomavirus (HPV) testing has improved the sensitivity for the detection of cervical pre-cancer and cancer as compared to Pap testing. Several HPV tests are commercially available and most target the DNA from 13 or 14 high-risk HPV types. The APTIMA HPV Assay however, detects HPV E6/E7 mRNA from 14 high-risk types of HPV: 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, and 68. OBJECTIVE: To determine the analytical performance characteristics of the APTIMA HPV Assay. STUDY DESIGN: Analytical sensitivity, analytical specificity, reproducibility, and the effect of potentially interfering substances was determined for the APTIMA HPV Assay on both the DTS (semi-automated) and TIGRIS DTS (fully automated) systems. RESULTS: The 95% detection limit for both systems was between 17 and 488 copies/reaction, depending on the HPV type. The assay did not cross-react with normal flora and opportunistic organisms that may be found in cervical samples, or low-risk HPV types. Spermicides, anti-fungal and anti-itch medications, whole blood, glacial acetic acid, and most lubricants did not interfere with assay performance. Those lubricants containing polyquaternium 15 did interfere with assay performance. Inter-instrument, inter-operator, inter-lot, and inter-run signal variability were <10% for >99% of the data. Intra-run variability was <15%, except for those samples with concentrations at or below the 95% detection limit of the assay. CONCLUSIONS: Based upon the analytical sensitivity, analytical specificity, and low variability, the APTIMA HPV Assay showed excellent performance and robustness.
