Health experts say it has potential to greatly improve treatment of the respiratory disease. An experimental test that can diagnose tuberculosis in less than two hours, making only one doctor visit necessary before treatment starts, is being hailed as a potentially significant advance against a disease that kills nearly 2 million people annually, most of them in developing countries.
"This is a very important discovery," said infectious disease expert Dr. Marc Siegel, an associate professor of medicine at New York University. "This could be an important tool worldwide, and even here in the United States."
