A Blood Signal Separated Three Tuberculosis States
In 217 people, a circulating ESAT-6 biosensor distinguished active infection, latent infection and exposure.
Summary
In 217 people, a circulating ESAT-6 biosensor distinguished active infection, latent infection and exposure.
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.
Why it matters
