This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
The R2D2 TB Network study is testing new tuberculosis (TB) screening and diagnostic tests to help doctors identify TB faster and detect drug resistance more quickly. Right now, many people with TB don't get diagnosed or treated in time. This research is comparing promising new tests against reliable existing tests to see which ones work best and are easiest for health workers to use.
About 40-60% of people with TB don't get started on the right treatment because diagnosis is slow or missed. This study exists to find faster, simpler tests that can be used in clinics and by frontline health workers, so more people can get diagnosed and treated early.

If you have symptoms or risk factors for TB, you would visit a study site and provide sputum (cough) samples so researchers can test you with new diagnostic tests and compare the results to standard TB tests. For the drug-resistance portion, if you have already been diagnosed with TB and rifampin-resistant TB, you would provide sputum samples to help evaluate faster drug-resistance tests. Health workers at the sites may also be observed and surveyed about how easy the new tests are to use.
