Scientists take step toward simple and portable tuberculosis tests for developing world
Date:10/8/2009

great sensitivity in saline solutions -- they were even able to detect a single molecular marker of a TB infection in solution. They have not yet built a functioning device that can detect hidden TB infections in blood or urine samples, and they have not yet tested the technology on samples collected in the field. Before any such detector is available for use in the field, it would have to be rigorously tested in clinical trials.

Moving in that direction, the team plans to do a survey of blood and urine samples from people infected with TB bacteria. This will help them conclude how sensitive they need to make any detector and which markers are the best to test.
