One Hour Flu Test Developed by Scientists in Move That Could Tackle Antibiotic Resistance
Scientists have developed a test which can diagnose flu in one hour, in a move which could speed up access to the right treatment and tackle antibiotic resistance. The instant swab tests, invented at University Hospital Southampton Foundation trust, mean specific viruses can be isolated, and given the right treatment, within 60 minutes. Currently such processses take almost a week, meaning thousands of patients are needlessly given antibiotics, fuelling spiralling drug resistance...

Smartphone, Finger Prick, 15 Minutes, Diagnosis—Done!
A team of researchers, led by Samuel K. Sia, associate professor of biomedical engineering at Columbia Engineering, has developed a low-cost smartphone accessory that can perform a point-of-care test that simultaneously detects three infectious disease markers from a finger prick of blood in just 15 minutes. The device replicates, for the first time, all mechanical, optical, and electronic functions of a lab-based blood test. Specifically, it performs an enzyme-linked immunosorbent assay (ELISA) without requiring any stored energy: all necessary power is drawn from the smartphone...
