Experts say that rapid home tests are still a helpful tool for stopping the spread of COVID-19, but they’re not foolproof. Here are a few explanations for why you might get a false negative result — and how to increase your chances of accuracy next time.

Dr. Paul Drain, associate professor of global health and of medicine in the UW School of Medicine, is quoted.

The Simplifying HIV TREAtment and Monitoring (STREAM) study, led by Global Health professor Paul Drain and recently published in The Lancet HIV, found that point-of-care HIV viral load monitoring and task shifting significantly improved viral suppression and retention in HIV care, as compared to standard laboratory-based HIV viral load testing. This study was the first randomized controlled trial to compare rapid point-of-care HIV viral load testing against standard of care lab-based HIV viral load testing, which usually takes several weeks to return results to patients.

Paul Drain—an Associate Professor in the Department of Global Health, Medicine and Epidemiology at the University of Washington—and his research team have received a new grant from the CoMotion Innovation Gap Fund, a program intended to help bridge the gap between academic research grants and the level of development needed to obtain investment. Drain’s project is titled “Rapid test for measuring adherence to antiretroviral therapy and pre-exposure prophylaxis”.
