The Ukweli Test Strips team (literally “truth” in Kiswahili) is developing low-cost, diagnostic test strips that screen for Urinary Tract Infections (UTIs) by identifying biomarkers in urine. One of the biggest problems in treating UTIs within the developing world is the degree to which the disease goes undetected, leading to further serious health complications. At the core of Ukweli is a common, household or small-office inkjet printer that has been repurposed to manufacture diagnostic test strips. Using an inkjet printer to lay down layers of biomedically active chemical reagents provides an opportunity to manufacture test strips at small scale, in quantities as needed, and locally. Our strips provide easy-to-interpret results in under 30 seconds while costing only 1/10th the price of current screening methods. Finally, the test strips are distributed through Community Health Worker (CHW) networks, thus providing them an income generating opportunity while bridging the last mile challenge and letting people get screened in the comfort and privacy of their homes.
