This is a misunderstanding of all testing then.

The two most common types of tests that are used right now are PCR and ELISA.
PCR with matching nucleotide fragments to a known viral strand and ELISA that is mostly antigen testing like your rapid flu's. This will create a highlighted molecular attachment that lights up a test strip and is often computer read when you're doing mass testing.

Sort of like a pregnancy test, there are thresholds to determine whether that's a positive or negative. And as above you have confidence intervals for sensitivity and specificity.

The test are in fact red is binary at that point. The thresholds are not arbitrary but instead used to find statistics.

While I understand the concern that I could go and adjust my PCR threshold after the fact, that simply not the way this works. The tests are created to a certain standard and then packaged with that information along with them.

The testing currently used is of the exact same technology that we use for rapid flu and PCR flu.

The major problem is significant variation and all of the different manufacturers as we spun things up emergently.

In the case of rapid flu it still doesn't carry a wonderful percentages. But again as above this percentages are known and with a large enough aggregate you can create confidence intervals.

Now if you start seeing confidence intervals that say we might have 100,000 cases or 500,000 cases in that case you start to see the real breakdown in poor testing, if you determine that one of those numbers requires one societal response and the other one requires another societal response.

When a positive test proves to be incorrect, are they removed from the positive counts? Like when OH Gov Dewine tested positive on the "quick" test but then tested negative on the more thorough test - allegedly.

Also - when people test positive and then have to keep retesting until they come up with a negative before they can continue whatever it was they were doing, does each positive test register as a positive? So 5 positive tests in a week are counted as 5 new cases?

A single positive test that was a false positive I will never know. There's not typically follow up. The person goes and quarantines as per CDC timeline recommendations because we have so little testing available. they don't have symptoms because they're actually negative.


If Ohio does what Texas does, I must fill out this three page patient under investigation sheet for that PCR test that's a send off. I assume if you're an official or some other higher capacity someone bumps that to the front of the line as is warranted. Regardless there's a huge sheet for the person's name and information to help run the test in an order for the most likely and highest risk.
So if they do what Texas does all of those tests will be linked together on that same individual and not count as one negative and three positives falsely inflating your positive rate to 75%.

Zero problems with testing in FL.

Maybe your guys could call our guys and get some advice?

It doesn't mean that the plural of that event is useful or relevant.

It's very useful to me. We can't afford to have inaccurate testing. Too much fuckery going on for that. If I had that test, not being a governor, I would've been send home for 2 weeks. And the result would've never been known. I would not have received other tests to see if the first one was correct. You think everybody that tests positive gets another go like our governor? It's extremly relevant and useful to me.

but you realize that just because it happened to someone 'famous' it doesn't change the actual statistical odds of a false result?

how is the fact that it happened to governor change anything about the factual testing reliability?

Not necessarily but all of my negative tests week after week after week count as separate tests so I'm singlehandedly driving our positive % down.

11 negatives mother bitches!!!

They should. Especially if they had the rapid test done initially since those are straight garbage. Their efficacy is roughly the same as flipping a coin.

I'm usually all for hanging shit on the Yanks, but I live in a state where we used the department of agriculture, the department of trade and the department of creative arts to run quarantine facilities (seriously). And we are still doing less testing per capita on many days than other Australian states with basically no coronavirus.

Dude, the Canadian government is in shambles and our news broadcasts (and the dupes who live on social media) are all "But we're better off than the States!!!"

The great Canadian weakness. You always compare yourself to a 3rd world shithole and think it makes you look good in comparison. We do that too, but not to the same degree. We still compare ourselves to first world countries as well.

Huh, I guess I can still hang shit on the Yanks after all.

New Zealand is Australia's Canada but it's not quite the same dynamic. Canada is much less of a shithole than the US whereas New Zealand is a bit more of a shithole than Australia, although there's not too much in it.

U.S. isn't really a shithole. It's just that the places in the U.S. that are shitholes are Grade A shitholes.
