Cepheid Announces New Diagnostic Technology to Aid World Efforts in Halting the Spread of Mycobacterium Tuberculosis (TB)
Date:3/24/2009

d's Chief Medical and Technology Officer. "In my opinion, this new test is one of the most important diagnostic developments to have occurred in many years. It is the most technologically advanced test for TB ever developed, yet it is simple enough to perform in all corners of the world, including resource-limited settings where it is most needed."

Currently, the most common testing method for TB is the sputum microscopy, or smear test, that has remained largely unchanged in its sophistication and sensitivity for over 100 years. The smear test has been proven to only detect around half of all active TB cases and is not capable of identifying drug resistance. Patients who remain undetected are often co-mingled within general hospital populations, placing others at risk of infection. Due to their low accuracy, smear tests are followed up with culture tests, which offer more accurate results but take several weeks. To determine drug resistance, culture testing can take months to return a result. For patients in the developing world, lengthy turnaround times of current test methods can lead to catastrophic consequences as the chain of transmission grows.

"We designed this test so that it could be used by someone with minimal training," said UMDNJ's David Alland, M.D. who collaborated closely with Cepheid and FIND with support from the NIAID. "We're gratified to find that it requires less hands-on work than the acid fast smear, long a standard method to identify tuberculosis, but it is much more sensitive."
