Sputum microscopy, which often delivers poor sensitivity in patients suffering from tuberculosis, is almost completely ineffective in those who also have HIV co-infection. The weakened immune system of an HIV-positive person is particularly susceptible to infection, resulting in one third of the 33 million HIV sufferers worldwide infected with TB. Left untreated, 90 percent of these people will die within months of first contracting the disease, reinforcing the urgent need for an accurate and rapid test.
About the GeneXpert(R) System Molecular Diagnostic Platform
The GeneXpert System is a closed, self-contained, fully-integrated and automated platform that represents a paradigm shift in the automation of molecular analysis, producing accurate results in a timely manner with minimal risk of contamination. The GeneXpert System is the only system to combine on-board sample preparation with real-time PCR (polymerase chain reaction) amplification and detection functions for fully integrated and automated nucleic acid analysis. The system is designed to purify, concentrate, detect and identify targeted nucleic acid sequences thereby delivering answers directly from unprocessed samples. Modular in design, the GeneXpert System has a variety of configurations to meet the broad range of testing demands of any clinical environment.
Based in Sunnyvale, Calif., Cepheid (Nasdaq: CPHD) is an on-demand molecular diagnostics company that develops, manufactures, and markets fully-integrated systems and tests for genetic analysis in the clinical, industrial and biothreat markets. The company's systems enable rapid, sophisticated genetic testing for organisms and genetic-based diseases by automating otherwise comple
