Clinical Evaluation of an IGRA Test for the Diagnosis of Active and Latent Tuberculosis

Methodology This is a single-center study carried out as part of routine patient care.

The aim of the study is to determine the performance of the 2nd generation TB-IGRA test in the diagnosis of tuberculosis.

It is planned to include 500 patients. An enrolment of 455 subjects will enable us to demonstrate sensitivity-specificity levels of 92% for a 95% confidence interval and a 0.05 degree of precision. To take account of non-analyzable samples or tests, the investigator will include 500 subjects
