Table 2 Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and likelihood ratios of Strong-LAMP versus microscopic diagnostic methods
From: First field study using Strong-LAMP for diagnosis of strongyloidiasis in Cubal, Angola
Diagnostic test | Sensitivity (95% CI) | Specificity (95% CI) | PPV (95% CI) | NPV (95% CI) |
|---|---|---|---|---|
Strong-LAMP/DSM | 100% (100–100%) | 67.60% (60.8–74.4%) | 14.5% (6.2–22.8%) | 100% (100–100%) |
Strong-LAMP/Baermann | 94% (83.9–105.0%) | 70.10% (63.3–76.9%) | 24.60% (14.5–34.8%) | 99.20% (97.6–100.8%) |
