Researchers at University of California Davis have developed an innovative Tuberculosis blood test that can accurately identify active and contagious cases of the disease. This advancement could significantly improve early diagnosis and help control the global spread of TB.
The newly developed Tuberculosis blood test addresses a major limitation in current diagnostic methods. Existing tests are unable to distinguish between active and latent infections, which has long posed a challenge for healthcare providers. This new approach focuses specifically on detecting cases that are capable of spreading infection.
Tuberculosis is caused by Mycobacterium tuberculosis, but not all infected individuals become contagious. Only those with active TB can transmit the disease through everyday activities such as coughing, sneezing, or even speaking. Identifying these cases early is crucial for preventing outbreaks.

According to Imran H Khan, in countries with high TB prevalence, nearly 35% to 40% of the population carries the infection in a latent form. While these individuals test positive, they may never develop symptoms, making it difficult to pinpoint those who are truly infectious.
Experts believe this breakthrough Tuberculosis blood test could transform global health strategies. By enabling faster and more accurate detection of active TB, the technology may reduce transmission rates, improve treatment outcomes, and strengthen efforts to eliminate the disease worldwide.
