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.
The latest FDA-approved model cost upwards of $20,000. The target price tag on Cirillo’s test is less than $1,000 for the reader and less than $5 per test. Additionally, the one-step test will require little technical expertise or resources, should take less than 30 minutes to carry out, and is easily transportable, making it an ideal candidate for field diagnosis in developing countries.
