Diagnostic features of phenotypic methods useful for the identification of yeasts and yeast-like pathogens in developing countries [24].
| Method | % Sensitivity | % Specificity | TAT | Reference |
|---|---|---|---|---|
| Rapid screening tests, e.g., β-galactosaminidase for identification of Candida albicans/dubliniensis | 97.8–100.0 | 85.7–100.0 | 5–60 min | [24] |
| Rapid screening tests, e.g., trehalase for identification of Candida glabrata | 89.3–100.0 | 74.1–100.0 | 30 s–24 h | [24] |
| Chromogenic agars, e.g., CHROMagar Candida, chromID Candida for identification of Candida albicans | 88.3–100.0 | 86.0–100.0 | 48 h | [24] |
| Manual biochemical methods, e.g., api 20C AUX, ID32C, rapID Yeast Plus | N/A | 86.0–100.0 | 4–72 h | [24] |
| Automated biochemical methods, e.g., MicroScan YID, VITEK 2 YST | N/A | 85.3–98.5 | 4–48 h | [24] |
TAT, turn-around time; N/A, not applicable. As the price for the phenotypic assays included are profoundly affected by the order scale and the tax amount, there is not a definitive price and it can vary from one country and one site to another.
