My wife, who works at the local hospital had an antibody test on Monday, the result came back positive.
There was one weekend, when she had a bad headache, and felt clammy, but her temperature was fine, we're pretty sure this was early on prior to staff testing, but can't remember when, can't think of any other time she may of had it. She has also had two Covid tests, both of which were negative.
Makes me wonder if I've had it, but I can't currently have an antibody test.
