| Interpretive Data: |
Positive: M. tuberculosis infection likely.
Negative: M. tuberculosis infection unlikely, but cannot be excluded especially when:
1. Any illness is consistent with TB disease,
2. Likelihood of progression to disease (e.g., because of immunosuppression) is increased.
Indeterminate: Results are indeterminate for responsiveness to M. tuberculosis antigens ESAT-6 or CFP-10.
Diagnosing or excluding tuberculosis disease, and assessing the probability of latent tuberculosis infection requires a combination of epidemiological, historical, medical, and diagnostic findings that should be taken into account when interpreting QuantiFERON®-TB Gold results.
|
| Note: |
The intended use of the QuantiFERON®-TB Gold assay is to detect latent TB infections among persons at increased risk for TB. The ability of the QuantiFERON®-TB Gold assay to predict the progression of latent tuberculosis infection to active tuberculosis has not been evaluated.
