a

ELISA ratios (signal/cutoff) were calculated as described by each manufacturer. For the kits from Organon (Org) and Embrabio (Emb), the results are average ratios of two determinations. For the kits from Murex (Mur) and Ortho (Orth), the results are ratios of a single determination. 

b

NT, not tested; Ind, indeterminate; Pos, positive. 

c

Neg, negative; tax, positive only for tax PCR.
