TABLE 3.
Sensitivity, specificity, and positive and negative predictive values of biological tests calculated per patient, excluding the four patients with probable ABPA
| Test type | Sensitivity (%)a | Specificity (%)b | Negative predictive value (%)c | Positive predictive value (%)d |
|---|---|---|---|---|
| rAspf4 IgE detection | 92.3 (12/13) | 93.7 (45/48) | 97.8 (45/46) | 80.0 (12/15) |
| rAspf6 IgE detection | 53.8 (7/13) | 91.6 (44/48) | 88.0 (44/50) | 63.6 (7/11) |
| Anti-Aspergillus IgG ELISA | 92.3 (12/13) | 87.5 (42/48) | 97.7 (42/43) | 66.6 (12/18) |
| IE | 92.3 (12/13) | 89.6 (43/48) | 97.7 (43/44) | 70.6 (12/17) |
| Total IgE detection | 69.2 (9/13) | 84.4 (27/32) | 87.1 (27/31) | 64.3 (9/14) |
| Culture of Aspergillus in sputum | 53.8 (7/13) | 85.0 (34/40) | 85.0 (34/40) | 58.3 (7/12) |
a
Sensitivity = true positive/(true positive + false negative).
b
Specificity = true negative/(true negative + false positive).
c
Negative predictive value = true negative/(true negative + false negative).
d
Positive predictive value = true positive/(true positive + false positive).
