āaO.D. values higher than the cutoff values are considered as positive. The IgG cutoff values (means of 10 negative controls plus 2.3 standard deviations) are 0.168, 0.345, and 0.219 for WCI, WCII, and rCom1. The IgM cutoff values (means of 10 negative controls plus 2.3 standard deviations) are 0.190, 0.371, 0.121, and 0.689 for WCI, WCII, rCom1, and rCom1 (amplified). bWC I: phase I whole cell antigen; WC II: phase II whole cell antigen. cBased on the amplified ELISA results. |
