Table 2 Sensitivity of testing methods in detecting target parasite eggs in equine fecal samples vs. prescreening with Mini-FLOTAC reference test
Sample population and target parasite | Test method and % sensitivity (95% CI) | ||
|---|---|---|---|
Group 1 (modified McMaster test) | Group 2 (modified McMaster test + NaO3 solution + Vetscan Imagyst) | Group 3 (modified McMaster test + Sheather’s sugar solution + Vetscan Imagyst) | |
All samples | |||
Strongyles | 99.9% (99.9–100%) | 99.9% (99.9–100%) | 99.9% (99.9–100%) |
Parascaris spp. | 95.3% (85.7–100%) | 67.3% (47.4–90.1%) | 99.9% (99.9–100%) |
Samples excluding those with low EPG countsa | |||
Strongyles | 99.9% (99.9–100%) | 99.9% (99.9–100%) | 100% (100%) |
Parascaris spp. | 99.9% (93.8–100%) | 77.5% (55.8–99.9%) | 98.3% (95.0–100%) |
