Anti-SARS-CoV-2 antibody levels in relation to the history of rRT-PCR-confirmed (n = 11) or unconfirmed (n = 3) SARS-CoV-2 infection in hemodialysis patients.
| rRT-PCR-Confirmed | Unconfirmed | |
|---|---|---|
| Number of IgG positive samples | 10 | 3 |
| IgG (BAU/mL) | 551.3 ± 483.8 529, 51–967 |
106; 534; 635 |
| Number of IgA positive samples | 10 | 3 |
| IgA (ratio to the cutoff) | 28.64 ± 46.25 5.4, 3.7–44.3 |
2.6; 6.2; 19.9 |
| Number of IgM positive samples | 1 | 1 |
| IgM (ratio to the cutoff) | 11.5 | 10.4 |
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.
