Reminder that at the moment this cannot happen without 1% of them dying and many more suffering long lasting or even permanent debilitation. If we ever get to the point where 80% of the population has had the virus, that would be a massive failure.
And the immunity may only last a year or two.

The FDA suggestion of doing two tests to reduce the percentage of false positives (since you can't rule out cross-reactivity with another coronavirus) looks like a good idea for broad testing. Of course this means higher costs.
> since you can't rule out cross-reactivity with another coronavirus If that causes a false positive, wouldn't a second test yield the same result?

#63I 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…
I've been waiting for a decent serum test because both my wife and I had "the flu" with symptoms consistent with COVID-19, me in mid-January and her in late February. How did you get the test?

#64'Specificity and Sensitivity' are new words that are now going to enter the public consciousness with regards to testing. Before Iraq War 2, in 2003, absolutely nobody knew the difference between a 'Shia' or 'Sunni' Muslim, and then it became more common knowledge. It's neat to see how these events shape awareness. Now every time a Nurse does a test, people will ask "What's the specificity?!" which can be a good or b…

p_false1 * p_false2

Where does it say that LabCorp uses the Abbott Architect platform? Couldn't find it on their website. (Unlike, say, healthlabs.com)

Because with a false positive antibody test then you can still contract and be a carrier. This is a problem for the immunity passport proposals (which I think are a terrible idea anyway, but that’s beside the point)
Why do you think immunity passports are a terrible idea? What else works better barring a long term vaccine?

Good anecdote. I also had a "weird cold" in February with symptoms that are unusual for me but typical of COVID-19, and have been waiting to get the antibody test. I kind of expect it to turn out the same way. (Otherwise, I would really like to figure out what the "weird cold" that everyone had in February was. Because it sure was weird, and everyone I know had it.)
