Anti-SARS-CoV-2 antibody levels in relation to the history of rRT-PCR-confirmed (n = 12) or unconfirmed (n = 13) SARS-CoV-2 infection in kidney transplant patients.
| rRT-PCR-Confirmed | Unconfirmed | p-Value | |
|---|---|---|---|
| Number of IgG positive samples | 11 | 13 | |
| IgG (BAU/mL) | 821.1 ± 1113.9 369, 207–746 |
256.5 ± 409.5 111, 64–207 |
0.016 |
| Number of IgA positive samples | 11 | 12 | |
| IgA (ratio to the cutoff) | 28.91 ± 43.34 12.5, 6.3–33.5 |
13.47 ± 16.58 6.4, 3.4–15.9 |
0.247 |
| Number of IgM positive samples | 0 | 3 | |
| IgM (ratio to the cutoff) | 1.51; 1.92; 3.06 | – |
Descriptive statistics (mean ± SD, median, and IQR) were calculated for samples classified as positive; when a low number of positive cases were observed, specific values are presented.
