NOTE: Multiple infection with other, i.e., low-risk types, was not reason for exclusion. HPV16 positivity by LA was compared with the cobas HPV16 channel, HPV18 positivity by LA was compared with the cobas HPV18 channel, and 12 other high-risk types by LA were compared with the cobas HR12 channel.

  • a1.5% of 7622 LA negative for HPV16 (among this group with single-type infections) were cobas-positive for HPV16, and 0.6% of 9162 LA negative for HPV18 were cobas positive for HPV18.
