Positive Agreement of Stratified ReEBOV Rapid Diagnostic Test Visual Scores

Visual Score	qRT-PCR Positive	qRT-PCR Negative	PPV (95% CI)
5	56	0	100 (96.3–100)
4	31	0	100 (88.8–100)
3	39	2	95.1 (83.5–99.4)
2	35	3	92.1 (78.6–98.3)
1	34	14	70.8 (56.7–81.9)

A total of 161 of 166 specimens had a visual signal score of ≥2, for a PPV of 97.0% (95% CI, 93.1%–99.0%).

Abbreviations: CI, confidence interval; PPV, positive predictive value; qRT-PCR, quantitative reverse transcription–polymerase chain reaction.
