If you have a chance, I have a couple of questions.
Two of my coworkers, each of whom I worked within six feet of for much longer than 10 minutes,tested positive on May 22nd and 23rd respectively. They last worked on May 18th and became symptomatic ~May 19th. I worked with them on numerous occasions for the 14 days prior to May 18th.
My employer facilitated testing for me and everyone I work with today. I have zero symptoms. I completed an antibody and nasal swab test-negative for antibodies and obviously waiting on the swab results.
Was it too early to test us based on the potential dates of exposure? I’ve read mixed opinions.
Timing of testing is a rock and a hard place: you want to catch infections before people get sick or infect others, and at the same time you risk false-negatives if you’re too early. One solution is to retest e.g. every second day, if it is possible (it’s probably not in most places). And neither swabs nor antibody testing detects 100% of cases, so that’s another argument for repeated testing. Also, a lot of antibody test kits are dog-shit inaccurate, especially for use in non-severe cases in a non-Chinese population (where most have been validated/quality assured from the manufacturer).
In your case, it sounds like the highest risk of you getting infected was 8-15 days before your tests. In that incubation time-frame there’s a good risk of false-negative results from the antibody test (esp. if you got infected closer to 8 days ago, most mild cases will not have developed antibodies yet). So that coming up negative was probably to be expected. It’s a good timing for swabs though, so the combination of the two makes sense, and if that one comes back negative you’re good (but look out for symptoms and get retested if you start to feel sick).
