Table 3. Frequency of Recognition and Area Under the Curve values for N. americanus L3 extract and recombinant SCP/TAPS proteins in the diagnosis of hookworm infection.
| Antigen | FoR (%)2 | AUC3 |
|---|---|---|
| N. americanus L3 extract | 66 | 0.86 |
| 01818 | 43 | 0.68 |
| 01068 | 52 | 0.74 |
| 10402 | 41 | 0.64 |
| 01070 | 60 | 0.77 |
| 01068 + 01070 + 104021 | 82 | 0.83 |
1 the minimal antigen combination (01070, 01818 and 10402) which gives the highest frequency of recognition.
2 the recognition cutoff was defined as the average response of the HW -ve group + 1SD.
3 area under receiver-operating characteristic curves generated for each antigen and the antigen combination, which determines the positive predictive value of infection.
