A report from the Associated Press, excerpt :
" Scientists are reporting a major advance in diagnosing tuberculosis: A new test can reveal in less than two hours, with very high accuracy, whether someone has the disease and if it's resistant to the main drug for treating it.
The test could revolutionize TB care and replace the 125-year-old process used now, which is slow and misses more than half of all cases, experts say. A better test would be a powerful tool to curb TB in poor countries, where most people spread the lung disease before they are diagnosed and treated, and many don't return for follow-up doctor visits to get test results.
In the United States, it could be a big help in inner city clinics, where diagnosing a drug-resistant strain on someone's first visit enables proper treatment right away."
