Biological Engineers at the University of Bath have developed a test that could help medics quickly diagnose urinary tract infections (UTIs), using a normal smartphone camera.
Similar in principle to a pregnancy test, the process can identify the presence of harmful E. coli bacteria in a urine sample in just 25 minutes. As well as being far faster than existing testing, it could make accurate UTI testing more widely available in developing nations and remote regions thanks to its potential to be made portable, and far more cheaply than existing lab-based tests.
coli is present in 80 percent of bacterial UTIs, so if it is found it tells medical professionals that an antibiotic treatment is needed. As well as a smartphone camera, the test, which could be adapted to detect a variety of bacterial infections, takes advantage of widely-available reagents and new micro-engineered materials. Researchers say the simplicity of the test, which has now passed the proof-of-concept stage, could deliver a new way to quickly identify treatments for patients in poorer or remote regions.
