Sensitivity analysis to estimate the type-specific serostatus of indicated serum panels. The HPV Negative serum panel (n = 146) is the panel of ‘likely negative’ samples used to determine the LODs, while the Natural Infection (n = 201), Bivalent Vaccine (n = 27) and Quadrivalent Vaccine (n = 29) panels are used to compare the seroprevalence estimates resulting from application of the indicated algorithm to determine the LOD.
