TSSA-WB and CS co-reactivity of samples from Latin American patients
| Sample origin | TSSA I/TSSA II vs. CS | |
|---|---|---|
| Co-positivity (%) | Co-negativity (%) | |
| Mexico | 36.1 | 78.0 |
| Colombia | 62.0 | 63.4 |
| Venezuela | 42.7 | 82.0 |
| Argentina | 97.1 | 100.0 |
| Paraguay | 93.0 | 71.4 |
Co-positivity = 100 × (frequency of TSSA-WB reactive samples/frequency of CS positive samples). Co-negativity = 100 × (frequency of TSSA-WB unreactive samples/frequency of CS negative samples).
