Dr. Gigi Gronvall, a leading international expert on tests, kindly joined us for a spirited tour d\u2019horizon.\xa0People need tests for multiple purposes on a continuous basis:\xa0You \u201ccan\u2019t just get one test and forget it\u201d since a test is just one moment in time. Sometimes however there are unrealistic, outsized expectations that tests will peer into the future.\xa0Why is the United States so prone to stumbling on tests?\xa0In 2020, responsibilities were thrown to the states, and antibody tests in the early days, approved by the FDA,\xa0were \u201cthe wild west\u201d where often you could get a more accurate result \u201cfrom flipping a coin.\u201d In 2021, \u201ca supply and demand market model\u201d for antigen tests predominated, and when demand collapsed, Abbott destroyed millions of doses.\xa0More recently, since September of 2021, and accelerating under the pressure of Omicron, things are improving -- but \u201cturning the ocean liner\u201d is slow. The $3 billion investment in affordable antigen supply and accelerated development of new tests is showing results.\xa0The more recent commitment by President Biden to provide 500 million antigen tests through the mail to Americans has promise. \u201cPeople want health information about their own bodies \u2026 people want access to tests. They know it is possible.\u201d\xa0"Perhaps that progress can be extended in the future to home flu tests.\u201d Dr. Gronvall also shared her thoughts on the Covid-19 controversy: put a focus on animal health and cleaning up live animal markets. And yes,\xa0we should cooperate with the Chinese:\xa0\u201cYou could get people together to exchange baseball cards and it would be productive.\u201d\xa0So why not focus on vaccinating the world? On widespread, pernicious misinformation: \u201ccut off the poison\u201d immediately at its source and invest in long-term education.\nDr. Gigi Gronvall is a Senior Scholar at the Johns Hopkins Center for Health Security and an Associate Professor in the Department of Environmental Health and Engineering at the Johns Hopkins Bloomberg School of Public Health.
