- Suitably controlled serosurveillance surveys are essential for evaluating human papillomavirus (HPV) immunization programs. A panel of plasma samples from 18-year-old females was assembled, the majority of the samples being from recipients of the bivalent HPV vaccine. Antibody specificities were evaluated by three independent laboratories, and 3 pools that displayed no antibodies to any HPV type tested or intermediate or high levels of antibody to HPV16, HPV18, HPV31, and HPV45 were created. These pools will be useful as control reagents for HPV serology.

- We performed an international proficiency study of Human Papillomavirus (HPV) type 16 serology. A common methodology for serology based on virus-like particle (VLP) ELISA was used by 10 laboratories in 6 continents. The laboratories used the same VLP reference reagent, which was selected as the most stable, sensitive and specific VLP preparation out of VLPs donated from 5 different sources. A blinded proficiency panel consisting of 52 serum samples from women with PCR-verified HPV 16-infection, 11 control serum samples from virginal women and the WHO HPV 16 International Standard (IS) serum were distributed. The mean plus 3 standard deviations of the negative control serum samples was the most generally useful "cut-off" criterion for distinguishing positive and negative samples. Using sensitivity of at least 50% and a specificity of 100% as proficiency criteria, 6/10 laboratories were proficient. In conclusion, an international Standard Operating Procedure for HPV serology, an international reporting system in International Units (IU) and a common "cut-off" criterion have been evaluated in an international HPV serology proficiency study.
