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…

If you're asymptomatic, would it also be positive?

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.

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."

Slightly off topic question: do people who have been infected with those varieties have any sort of immunity against covid-19?

I've been looking forward to seeing this kind of test just for this reason so we can whitelist people. But since a large percentage of people don't have symptoms how can you tell if you're still shedding the virus?

Big chance of getting false-positive. People will think they're clear and won't distance themselves from vulnerable. While they may be carriers.

I don't know why you are being down voted. The risk is for false-negative, but you are right that people might think this is going to clear them.

Even the manufacturer/supplier warns that: "Negative results do not preclude SARS-CoV-2 infection and should not be used as the sole basis for patient management decisions. Negative results must be combined with clinical observations, patient history, and epidemiological information."

They also indicate: "The sensitivity is 97.90 %, the specificity is 91.77%."

But when you read the technical document you realize that this was for a subset of patient. The real numbers are 88.7% and 90.6% respectively, and again these are for severe cases.

A test for who is immune seems very important a few months down the road!

Oh that's easy - just find one of those Floridian beach goers. Anyone still fine in three weeks is immune.

Yes since it’s an antibody test.

This will make it easier to tell if a symptomatic person has COVID or something else. But it won't help with early detection, which is what is most urgently needed.

Early detection is utterly irrelevant at this point it’s endemic at most places now.
