NCT04148053

Brief Summary

Diagnosis of active and latent pulmonary tuberculosis, as well as extrapulmonary tuberculosis, is still a major challenge of TB control in China. This observational study aims to evaluate TB-antigen responsive T cell markers in the diagnosis of tuberculosis and extrapulmonary tuberculosis and try to find new prompt and cost-effective laboratory tests for active TB screening.

Outcome Measures

Primary Outcomes (2)

  • Positive rate and negative rate

    Evaluation of the positive rate and negative rate for each T cell marker

    2-3 month after sampling

  • Receiver operating characteristic curve

    The AUC of each T cell marker will be analyzed and compared

    2-3 month after sampling

Study Arms (2)

Active TB

Subjects met the following: 1. Either Pulmonary or Extra-pulmonary tuberculosis patients 2. TB Bacteriological evidence obtained by culture or Xpert MTB/RIF from at least 1 specimen.

Diagnostic Test: TB-antigen responsive T cell markers

Latent TB

Subjects met the following: 1. TB Contact in history. 2. Chest X-ray suggestive of non-TB. 3. without any symptoms suggestive of TB. 4. TST and/or IGRA positive.

Diagnostic Test: TB-antigen responsive T cell markers

Interventions

A blood test including a series of T cell markers which are responsive to TB antigens

Active TBLatent TB
