I believe these require a blood draw.

People who have diabetes often do blood tests daily, at home, on their own, drawing a drop of blood from their finger with a lancet. If they can get it down to using a drop of blood, I think people could be convinced to test at least one member of the household daily. That should at least give us enough information to measure spread. It would be new for most people but it's not unprecedented and I think people would…

That isn't true. The bats that it mostly likely come from are in China - but in Southern China about 1000 miles from Wuhan.

In Wuhan is the lab that was researching the virus from those bats.

This is encouraging. Two negative viral tests and a positive antibody test, and people should be able to get an ID that says they're exempt from movement and mask restrictions. (To discourage faking this, getting that ID should also turn eligibility for the Emergency Care Benefit, since they can work safely.) There's still argument over how long immunity lasts, but it has to be at least two or three months, or there…

>>> ..they're exempt from movement and mask restrictions ... There's a negative repercussion of people around such folks getting a false-impression that masks are not a serious need (if this is in question, that's a different discussion). It also creates a possibility of visible 'haves' and 'have-nots', which can cause trouble. I think having uniform messaging for movement/masks irrespective of antibody presence will…

> they can work safely Maybe. If only 1% of your employees could work safely, it's probably not worth opening the doors and paying them to try to get something done in the absence of the other 99%.

I took this antibody test through LabCorp on Friday and tested positive. I have been in strict (see: paranoid) isolation with one other person since March 7 and haven't felt sick or anything close to it since then. I did have what I thought was a strange flu/cold early February with a sore throat, post-nasal drip, wildly varying body temperature, and lower back pains. In hindsight those are COVID-19 symptoms. the per…

Is a 99.9% specitivity good enough though to conclude you had covid? Assuming you are in the US, your prior on having been infected in early February is well below 0.1% (not sure how much the covid-like symptoms would boost that). So conditionally speaking, it seems quite plausible this is a false positive.
