That's actually better, some competent people said, because the chance of contact with virus carrying bodily fluids is eliminated
Except people generally don't like needle sticks.
> The sensitivity is 97.90 %, the specificity is 91.77%. This seems like it could provide a false sense of security to many if used widely by the general population.
And also this. >Positive results may be due to past or present infection with non-SARS-CoV-2 coronavirus strains, such as coronavirus HKU1, NL63, OC43, or 229E.
They also cleared the Pinnacle BioLabs assay. You can order a 2-pack or a 25-pack. https://www.pblabs.com/products/pinnacle-biolabs-covid-19-no... Mine arrived in the mail this morning.
This is an antibody test which will only be positive days after the onset of symptoms. This is principally useful for several purposes: 1. Figuring out who to isolate in hospitals if the RNA test isn't available in sufficient quantity 2. Understanding who has already recovered from COVID-19 and is thus immune with all that implies in terms of inability to spread the disease and reduced need for PPE 3. Enabling us to…

It also means that, if that number is correct, 8.23% of not-yet-infected people will test positive. At a time when only 0.01% of people are infected, that means that 8.2301% of people will test positive, and of those people, on average one person† of every 82301 people will have the infection; the other 82300 are all false positives. They'll need to improve that for this to be useful, since at the time 1% of the popu…
Keep in mind this is an antibody test, it only works >1 week after someone gets sick. It might help differentiate COVID from Flu if someone is sick, but it's not great for screening otherwise healthy people.
I'm curious what you're basing the 1 week off of? As far as I can tell the company isn't reporting any data about how long it takes, but they think that it is likely to be similar to SARS per their manuscript: https://coronachecktest.com/wp-content/uploads/2020/03/Devel... > It was reported that after SARS infection, IgM antibody could be detected in patient blood after 3-6 days and IgG could be detected after 8 days…
There is a graph at the bottom of their homepage: https://coronachecktest.com/wp-content/uploads/2020/03/antib...
The first red dot is at the 7 day mark.

What if you're asymptomatic?

Are there any reviews? Any third party verification? How do I know that this is legitimate? These are sincere questions, I'm not just being difficult.

Bear in mind in relation to immunity -- "Positive results may be due to past or present infection with non-SARS-CoV-2 coronavirus strains, such as coronavirus HKU1, NL63, OC43, or 229E."

There is evidence that people can become re-infected, so antibodies aren't enough.
Citation? I saw the one story about people "testing positive again" but that seemed to be a testing abnormality, not people getting sick a second time.
