TABLE 2.
Performances of seven serological tests with sera from those with known Mantoux test results and anonymous controls
| Test | No. (%) of seropositive Mantoux test controls
|
P value for Mantoux test-positive versus -negative controlsa | No. (%) of seropositive anonymous controls (n = 50) | ||
|---|---|---|---|---|---|
| Total (n = 204) | Mantoux test positive (n = 89) | Mantoux test negative (n = 115) | |||
| ICT Tuberculosis | 9 (4) | 5 (6) | 4 (4) | 0.15 (NS) | 6 (12) |
| RAPID TEST TB | 26 (13) | 15 (17) | 11 (10) | 0.03 (S) | 7 (14) |
| TUBERCULOSIS IgA EIA | 14 (7) | 10 (11) | 4 (4) | 0.03 (S) | 19 (38) |
| PATHOZYME-TB complex | 7 (3) | 6 (7) | 1 (1) | 0.01 (S)b | 2 (4) |
| PATHOZYME-MYCO IgG | 22 (11) | 9 (10) | 13 (11) | 0.7 (NS) | 5 (10) |
| PATHOZYME-MYCO IgA | 30 (15) | 18 (20) | 12 (10) | 0.01 (S) | 14 (28) |
| PATHOZYME-MYCO IgM | 40 (20) | 17 (19) | 23 (20) | 0.48 (NS) | 0 (0) |
a
Significantly different results are indicated by a P value of ≤0.05. S, statistically significant; NS, not statistically different.
b
Fifty percent of the cells in the frequency table had expected counts of less than 5. This result should therefore be interpreted cautiously.
