PCR (20 types; 18 HR types+2 LR types): 16, 18, 26, 31, 33, 35, 39, 45, 51, 52, 53, 56, 58, 59, 66, 68, 73, and 82 + 6 and 11

HC2: (13 HR types) 16,18,31,33,35,39,45,51,52,56,58,59, and 68

Chip (26 types; 18 HR types+8 LR types): 16,18, 26, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, 68, 69, 73, 53 and LR: 70, 6, 11, 32, 34, 40, 42, 43, 44, 54, 55, 57, 61, 62

1*: PCR LR does not cover HPV-70 type.

2*: HC2 HR does not cover HPV-53 type.

3*: HC2 HR does not cover HPV-66 type.

4*: HC2 and PCR PR do not cover HPV-83 type.

5*: PCR LR does not cover HPV-54 type.

6*: PCR LR does not cover HPV-67 type.

**: HR2 was not considered in this analysis because HR2 excludes LR HPV types.
