Numerous blood tests that claim they detect antibodies for those who have been exposed to the coronavirus have been surging onto the market. While the Food and Drug Administration doesn’t normally set standards for these tests, even the ones that meet informal government standards may not be accurate. It cannot be clear if someone who has antibodies to the coronavirus is actually immune as these antibodies aren’t even produced until around a week after you become infected. Many of these tests also claim they are 99% accurate, but studies have shown them to be far less truthful and they can cost upwards of $49.
