The BA.5 variant is spreading across Northeast Ohio and the share of people testing positive in Cuyahoga, Lorain, Summit and Mahoning counties is nearly one in five, according to the Centers for Disease Control and Prevention.
That means many people are once again turning to testing 鈥� particularly at-home tests 鈥� to make decisions about whether to go out and whether to wear masks.
Unfortunately, at-home COVID-19 tests are less accurate at detecting the BA.5 variant than tests used in doctor鈥檚 offices and hospitals, according to research from Harvard University.
But experts say there are steps you can take to improve accuracy and prevent getting a false negative on a COVID-19 test.
鈥淥ne strategy that鈥檚 often used is serial testing, meaning testing more than once on consecutive days using the antigen test," said the Cleveland Clinic鈥檚 Dr. Daniel Rhoads. An antigen test is an at-home test.
Making sure you get a good sample to put into the at-home test is important, Rhoads said.
鈥淲hat tests are good at detecting are a lot of virus, so the antigen tests are going to be positive if there鈥檚 a lot of virus there, so a good sample is helpful,鈥� he said.
That's how user error can make at-home tests less accurate, said Dr. Amy Edwards of University Hospitals. The tests rely on the person scraping the back of their nose, which can be difficult to do by yourself.
鈥淚f you鈥檙e willing to do it, you can do it. But if you鈥檙e not willing to do it, then you should just go to the doctor," she said. "If you鈥檙e just going to take like a quick little... swab of your nose, you鈥檙e wasting whatever money you spent on that test.鈥�
