60-70%, but a sampling of urgent care patients isn't a great population to figure out whether herd immunity exists in the broader population.

Roche as well. I'm doing the Abbott one today at 2:30, just got it scheduled.

I think the Abbott and Mayo ones are good


You're damn right ours are good. Roche also has produced some good ones, I believe.

And again, antibody tests are not accurate.


Some were deemed bad, yes.

But antibody testing isn’t some new thing. Most legit testing companies have a 99% rate. Stop spreading lies, fool.

Looking at 256 samples – comprising samples from 103 from patients with COVID-19 detected by PCR testing and 153 samples from patients without the disease – they found that Abbott's test, which runs on the company's Architect platform, had a specificity of 99.4 percent and a sensitivity of 93.8 percent 14 days or more after symptoms began.

Meanwhile, Euroimmun's assay, running on Inova Diagnostics' Quanta-Lyser 240 instrument, had a specificity of 94.8 percent and a sensitivity of 85.4 percent 14 days after the onset of symptoms. For Euroimmun's test, borderline results were primarily reported as positive results.


Texas baws, these are available from remedy. Drive thru blood draw after a 15 minute video appt with a doctor. I'm paying $0.

Edit: just did it. Took 2 minutes and didn't even have to leave the car.

Gave blood the other day, they’re doing antibody testing when they run everything through the lab.

Should hear back in two weeks.

Typically 70%

60-70%


This was the initial estimate based on everyone being equally susceptible to infection.

This is likely not the case, it's likely much lower.

The general range for all diseases is 50-90%. Being 60-70% is already adjusted downwards from more contagious diseases.

True, but there is mounting evidence that 30-60% of the population may be innately immune. IF that turns out to be the case, that drastically reduces what is needed for herd immunity.

I appreciate your posts but I honestly have no idea why it's surprising that half of the patients at an urgent care facility at the epicenter of a pandemic show antibodies for the virus. It just seems logical.

So 50% of covid patients had covid antibodies? I don't think this means what people think it means.



What do you think it means?

Wut?

A lot of healthy people are currently going to urgent cares just to get antibody tested. Most are charging like $100 cash and I think BCBS is paying for it in several states.


currently yes, but the 11,000 tested in the study went to urgent care in April

I know what it means. 50% of patients had it meaning either 50% of the people thought they had it so they went it to check or 50% of people had it and now have antibodies. It doesn't mean 50% of New York or Brooklyn had it.

Look I'm all for seeing numbers that say we're close to herd immunity. Hell, I just got an antibody test. This doesn't seem to be saying that though.

Additionally, while the data are preliminary, our study shows that patients who experienced a
more severe clinical course of SARS-CoV-2 infection are more likely to have higher serum levels
of SARS-CoV-2 IgG antibody
. Therefore, it follows, that these individuals are more likely to
benefit from protective immunity and are less prone, at least in the short-term, to reinfection
by SARS-CoV-2.


The bold part goes along with your hypothesis regarding asymptomatic/those with a T cell response not producing many antibodies.

That second sentence does potentially sound a bit worrisome, but that's more of an unknown than a worry.

I'm not sure, but I know how we can get to that number faster...

Also, what is significant about herd immunity? If you're one of the X % that doesn't have antibodies, are you any less screwed than before society passed the "herd immunity" threshold?
