It's available. The hospitals are using it to test their employees. It was a same day result. The problem is that no one trusts it. Your body takes a while to develop the antibodies apparently, and if you don't really get sick you don't really show them. We know my wife has been exposed numerous times. We think my daughter has even had it. My wife tested negative for antibodies. It's not completely useless information of course. It's just incomplete.
Flattening the curve was always about making sure we could handle the rate of illness. It's not supposed to make everyone safe. The goal posts have definitely been moved as evidenced by the Stay Home Save Lives yard signs all over the neutral ground. That was never really the point of staying home.
The only way forward with this thing is through it. It has to run its course and it may already have largely done that.
