Can COVID-19 tests detect BA.2 variant?

Bernadette Boden-Albala, DrPH, MPH, director and founding dean at the University of California, Irvine Program in Public Health, told Verywell that people should test a few times to make sure results whether positive or negative are truly accurate. … “Early studies show that if you’ve previously had Omicron, you likely have good protection against BA.2, at least for now,” Boden-Albala said. “We’re still learning more about how long that immunity lasts.”
