Table 2. Number of samples displaying discrepancies between the assays targeting the 5′NCR only and the reference method in the 500 samples infected with either subtype 1a or subtype 1b.

Result with the reference method	Result with the 5′NCR targeting method	Trugene HCV 5′NC Genotyping Assay	INNO-LiPA HCV 1.0
HCV subtype 1a	Subtype 1b Subtype 1a or 1b* Genotype 1, indeterminate subtype Genotype 1, other subtype Other genotype Result not interpretable Negative PCR amplification	40 0 12 0 0 0 2	40 4 25 0 0 0 1
HCV subtype 1b	Subtype 1a Subtype 1a or 1b* Genotype 1, indeterminate subtype Genotype 1, other subtype Other genotype Result not interpretable Negative PCR amplification	7 0 11 0 1 1 5	4 1 15 0 0 0 3

^*The assay has been unable to differentiate between subtypes 1a and 1b.
