| Test | Antigen | mg per well of antigens | Serum dilution | Anti-IgG peroxidase dilution | Sensitivity, %† | Specificity, %‡ |
|---|---|---|---|---|---|---|
| Schistosoma spp. | AWA S. bovis | 0.05 | 1:100 | 1:2,000 | 94 | 97 |
| Filaria | AWA Dirofilaria immitis | 0.08 | 1:100 | 1:5,000 | 90 | 97 |
| Fasciola spp. | E/S F. hepatica | 0.04 | 1:100 | 1:2,000 | 100 | 96 |
| Trichinella spp. | L1 T. spiralis | 0.03 | 1:100 | 1:2,500 | 100 | 91 |
*IgG, immunoglobulin G; AWA, adult worm antigens; E/S, excretory/secretory antigens; L1, larvae 1 antigens.
†Sensitivity: serum samples from patients infected with schistosomiasis (35), tropical filariasis (20), fascioliasis (12), and trichinellosis (3) were used.
‡Specificity: serum samples from healthy controls from sub-Saharan Africa (41), from healthy Spanish blood donors (52), from patients with other isolated helminthic infections (45), from patients with protozoa infections (25), and from patients with bacterial or viral infections (19) were used.
