Problem being addressed
Once a patient is known to be infected with tuberculosis (TB), the next step is providing anti-TB drugs to treat the disease. However, some TB patients poorly absorb these drugs, leading to inadequate treatment the infection.
Detailed description of the solution
Vinnard proposes to develop a low-cost urine test to measure the bioavailability (the amount of the drug that is absorbed) of anti-TB drugs in patients with TB. The proposed test will be point-of-care, safe, accurate, and inexpensive, making it viable in resource-limited settings. Specifically, the project will evaluate urine colorimetry, “a technique used to determine the concentration of colored compounds in a solution by measuring its absorbance of a specific wavelength of light.”
