Evaluation of the performance of an in vitro test, the STANDARDTM F TB LAM Ag FIA (SD BIOSENSOR, INC.) for the early diagnosis of tuberculosis (TB) infection. This test is for in vitro professional diagnostic use and intended as an aid to early diagnosis of tuberculosis infection. The test will be used according to the instructions for use (IFU).
STANDARDTM F TB LAM Ag FIA is a fluorescent immunoassay which detects lipoarabinomannan in human urine sample. The test evaluated in this study may provide benefits for the development of non sputum-based, less invasive tuberculosis diagnostics that include easier to collect biological samples. The study can therefore be relevant for updating WHO guidelines for TB diagnosis. The results of the STANDARDTM F TB LAM Ag FIA will be interpreted according to the manufacturer´s instructions and will be compared to the results of the test performed to confirm the pulmonary TB, the extrapulmonary TB or the pulmonary NTM diagnosis (intention to treat assay). The test will be repeted at the end of the anti-TB therapy to evaluate if the test can be used as marker of treatment response. Healthy subjects without exposure or risk for TB factors will serve as a proxy for specificity; subjects with confirmed TB will serve as control group to estimate sensitivity.

| Evaluate the diagnostic performance of a new test based on the detection of lipoarabinomannan (LAM) antigen in human urine using immunoassay | STANDARDTM F TB LAM Ag FIA is a fluorescent immunoassay for the qualitative detection of specific antigen from mycobacterial lipoarabinomannan (LAM) in urine. The test should be used with the STANDARD F Analyzers manufactured by SD BIOSENSOR that are Europium (Eu) based fluorescent immunoassay system and have been designed for easy and reliable measuring of diverse parameters. The test result of a specimen is given either as Positive or Negative with a COI (cut off index) value. The test may provide benefits for the development of non sputum-based, less invasive tuberculosis diagnostics that include easier-collect biological samples. The results of the test will be compared to the results of the test performed to confirm the pulmonary TB, the extrapulmonary TB or the pulmonary NTM diagnosis Healthy subjects without exposure or risk for TB factors will serve as a proxy for specificity; subjects with confirmed TB will serve as control group to estimate sensitivity. | 12 months |

| Exploratory Objectives Evaluate if the test can be used as marker of treatment response (only for PTB subjects) | The test will be repeated at the end of the anti-TB therapy to evaluate if the test can be used as marker of treatment response.We want to evaluate whether, in the face of therapeutic success, the test becomes negative (reversion of results). | 6 months |
