New skin patch test detects tuberculosis through emitted chemicals

Early detection of tuberculosis is crucial in combating the disease, which claims 1.5 million lives annually. Current diagnostic methods are slow and costly, hindering eradication efforts. A new skin patch test, detecting TB through emitted chemicals, shows promise as an inexpensive, non-invasive screening tool. The test could be particularly beneficial in rural areas, eliminating the need for clinic visits. This breakthrough could also aid in detecting other diseases like malaria.
