| Samples | Indirect IgG (Fc) | Capture IgG (Fc) | VNT |
|---|---|---|---|
| Positive 1 | 16.3 | 5.2 | Positive |
| Positive 2 | 26.2 | 6.7 | Positive |
| Positive 3 | 21.2 | 7.0 | Positive |
| Positive 4 | 25.5 | 12.1 | Positive |
| Suspected positive 1 | 15.2 | 0.8 | Negative |
| Suspected positive 2 | 7.7 | 1.7 | Negative |
| Suspected positive 3 | 7.5 | 1.5 | Negative |
| Suspected positive 4 | 3.4 | 1.2 | Negative |
