Positive, OD ≥ 0.4; gray zone, 0.3 ≤ OD < 0.4; negative, OD < 0.3. Cryptodiag sensitivity and specificity were as follows: for threshold of OD ≥ 0.4, sensitivity, 97.0% (32/33), and specificity, 98.3% (116/118); for threshold of OD ≥ 0.3 (including gray zone), sensitivity, 100% (33/33), and specificity, 96.6% (114/118).
