The current standard for screening for the presence of tuberculosis (TB) is the Tuberculin Skin Test (TST), which requires patients to return for a physical "read" of the TST injection site by a trained clinical professional two to three days after the initial injection. This is a major inconvenience for patients, especially in fields that mandate annual TST testing such as the healthcare sector and other social services, and is costly for clinical sites.

Leveraging cloud-based resources and state-of-the-art biometrics, we designed a system for asynchronous telehealth TST injection site readings, eliminating the return visit, improving the specificity of the "read," and through geolocation, creating a novel method for detecting TB blooms for strategic public health actions.
