Pullman’s Veterinary Medical Research & Development is conducting a new method to collect COVID-19 samples using previously worn face masks. The sample collection allows for early detection of COVID-19, even among people who are asymptomatic and presymptomatic. Dr. Siddra Hines, VMRD veterinarian and research scientist, said the sample collection is not a substitute for the nasal swab method, but an early indicator to keep more people safe. “This is more like a first line of defense, an early warning system if you will,” Hines said. The sample collecting is done by punching a hole in a used medical-grade disposable mask. Then, employees place the sample in a vial with a liquid in it that preserves the sample while it is prepared for testing, Hines said.
