Evaluation of yield of T.Spot and tuberculin skin test (TST) in patients categorised as low risk
| Number of patients identified for chemoprophylaxis (%) | Number of patients missed (would have been identified via other methods) (%) | Sensitivity versus double testing combination (%) | |
|---|---|---|---|
| T.Spot +ve | 21 (19.1) | 18 (16.4) | 53.8 (37.2–69.9) |
| TST +ve | 26 (23.6) | 13 (11.8) | 66.7 (49.8–80.9) |
| T.Spot and/or TST +ve | 39 (35.5) | – | – |
Data shown as n (% of low risk sub-group 110) or sensitivity (95% CI).
