| IgA TcdA | 39882 ± 2737 | 428 ± 17 | 230 ± 47 | NA |
| IgA TcdB | 55708 ± 6601 | 578 ± 11 | 480 ± 18 | NA |
| IgA C. difficile | 38222 ± 7014# | 2021 ± 292 | 516 ± 146 | 235 ± 51 |
± represents standard deviation. Values and standard deviation rounded up to the last digit. NA = not available because of the non-sigmoidal progress EC50 calculation was not possible. Pearson R2 was >0.99 for all fits, except #0.97.
