I know.I took two.They have a lab Corp and Quest Diagnostics one that is supposed to show if you had it,but they are not reliable.I think my proof should be being perfectly healthy to going to disabled and not one Doctor can find a thing in 2 1/2 years.The destruction that Covid does to the body must hide from conventional tests.So many people I have talked to with long covid told me the tests won't show a thing.
