Boulder, Colorado (CBS4)– Researchers at the University of Colorado give a new meaning to the question, “Did you pass the odor test?” Believing in the scratch and sniff test may be the best hope to control the spread of COVID-19 after effective vaccination.

Roy Parker, a CU biochemistry professor, admits he was initially skeptical of the test. Derek Toomre, a colleague at Yale University and a former CU undergraduate student, developed it and asked Parker and CU computer scientist Dan Larremore to study its effectiveness.

“I think the amazing thing is that it worked better than we expected,” Parker says.

He and Larremore have developed mathematical models for a variety of scenarios, including university campuses, to study how effective olfactory tests are in controlling infection. They found that using it every three days could identify more infections than using the gold standard PCR test once a week.

“80% of people with COVID lose their sense of smell,” Parker explains.

Fever, on the other hand, is only 25% and lasts only a day or two, while the sense of smell is lost for more than a week.

Parker says many of them are unaware of it, but the test says “say.” You need to take the actual test. “

The Scratch and Sniff test is a screening tool, but Parker says it costs $ 20 per COVID-19 test and costs 50 cents per card, reducing the spread of the virus, especially in large venues like soccer. Can be very helpful to you. Stadiums, concert halls, airports.

“If we can catch 80% of people who have a COVID but don’t know it, that could have a big impact. We are now looking for a solution. We are in a pandemic. And I can’t wait for the perfect solution. This is something we can try now, it should work, and we should try it, “Parker said.

Parker is currently planning to test the test in a real environment like a dormitory. He says he is seeking urgent approval from Toomre’s company U-Smell-FDA, and once it’s done, it can start creating hundreds of millions of tests a week.
