Why does TB remain the second leading cause of mortality from an infectious disease? Simply because we lack an accurate, reliable, affordable, and accessible diagnostic tool in the areas of the world where it is most needed.

This new technology, using fluorescent substrate, provides a much faster and reliable test than smear microscopy, which remains the most widely used test. The test requires a single sputum sample, reactive substance and portable device, eliminating the need for laboratory testing. This diagnostic tool will be most valuable in developing countries, which lack the infrastructure and resources to screen infected patients.
