Problem being addressed[edit]

There is a lack of an accurate, swift, and low-cost test for the diagnosis of TB. These factors make the disease prevalent in resource-limited settings, leading to the continued spreading of the disease.

Detailed description of the solution[edit]

Partnering with industry and business, Madhukar Pai and his team seek to develop a simple strip test for extra-pulmonary TB with greater accuracy than current processes. A strip test generally involves the detection of lipoarabinomannan (LAM) in urine. The presence of LAM in urine can rule-in TB in HIV-infected persons, and lead to the identification of, based on clinical trials, patients with advanced immunosuppression and thus a more severe form of TB. They plan to make each test cost less than two dollars.
