Fast Track Diagnostics Ease TB Dangers
Using laser Raman spectroscopy, a simple breath test will analyze a patient for rapid, on-site diagnosis. The inner walls of the collection chamber they breathe into are chemically treated to capture the organic TB biomarkers present in the patient breath. A laser beam is then passed through the chamber, and the transmitted light is detected as a function of the raman shifts, determining the frequency.
The diagnosis of TB is then performed based on the chemically-specific spectroscopic signatures of the TB biomarkers present in the breath. This process will provide a novel TB sensor which is non-invasive, accurate, sensitive, and label free. By developing an easy to use non-invasive optical sensor, immediate TB diagnosis can be provided without the aid of specialized laboratory personnel. This is also easily portable to remote areas with lack of healthcare infrastructure
