    "body_text": "Researchers presenting at ADLM 2026 measured circulating ESAT-6, a tuberculosis-associated protein, in blood from 217 people and reported stepwise signal differences among active disease, latent infection and exposed controls. A faster blood test could reduce dependence on sputum, particularly for patients who cannot produce a sample. The conference study used known-status samples and needs prospective validation before it can guide diagnosis.",
