VCA-IgA results of 20 patients calibrated by the reference according three sample categories detected by 6 kits. Line chart of VCA-IgA results detected by each of 6 kits in three sample categories a negative; b low positive; c, medium/high positive. The mean VCA-IgA concentration of each patient by 6 kits divided into three sample categories were used LSD test to make multiple comparisons between the groups. d, negative; e low positive; f, medium/high positive. It has been marked out, when the difference between the two groups is significant (p < 0.05). * New Industries group was different from other kits group in medium/high positive categories by LSD test (p < 0.05)
