^aControl samples were obtained from HPV16 DNA-negative virginal women (serum set 1). PVP-360 was added to the conjugate buffers at a final concentration of 0.8%, Tween 20 was added at a final concentration of 0.05%, milk was added at a final concentration of 5%, and PVA-50 was added at a final concentration of 0.5%. Values represent the mean OD of each sample run twice.
