CORONA CDC Withdraws Use of PCR Test for COVID and Finally Admits the Test Can Not Differentiate Between the Flu and COVID Virus

I posted that OP article on my FB and was immediately thrown into FB jail for 24 hours and no posting on any of my groups for 2 days!! That will show me...... of course when I didn't agree with their decision, they said they couldn't look into it as they were short staffed on Fact Checkers with Covid

The covid pcr does not test for the flu. It cannot tell you if you have the flu or not. It only tells you of you have covid or not.

The flu test only tells you of you have the flu. It can't tell you if you have covid or not.

Neither can differentiate because the only test for one and not the other.

New pcr tests CAN test for both and DO differentiate.
I don't think you understand the word differentiate.

If a testing center followed procedure, they tested for flu, then for COVID. That was how flu was ruled out when using the PCR test. From personal experience and from friends, not all testing centers tested for flu first. Testing centers did not get reimbursed for flu testing or the tests themselves, only for COVID. So there is a good chance that COVID positives from those centers could have been flu.
And one of the reasons why this test is going away.

No, it didn’t matter what order the test was given; flu tests were positive or negative for flue; Covid tests were positive or negative for Covid

Not based on the release information. The PCR test could not differentiate between flu and COVID, so flu was supposed to be ruled out. In the beginning it was. (One flu test ran me almost $200 oop, for the visit and test before they could test for COVID.) After the first few months, COVID tests were plentiful and free. Flu tests were not. So many centers stopped testing for flu.

Quote and link to the supposed “release information” because that is not remotely accurate.

The original Covid PCR test detects the presence of a nucleic acid found only in the covid virus. It doesn’t detect flu, period.

Here is the link to the original CDC announcement


And here is the relevant statement:

In preparation for this change, CDC recommends clinical laboratories and testing sites that have been using the CDC 2019-nCoV RT-PCR assay select and begin their transition to another FDA-authorized COVID-19 test.

CDC encourages laboratories to consider adoption of a multiplexed method that can facilitate detection and differentiation of SARS-CoV-2 and influenza viruses.

Such assays can facilitate continued testing for both influenza and SARS-CoV-2 and can save both time and resources as we head into influenza season. Laboratories and testing sites should validate and verify their selected assay within their facility before beginning clinical testing.

There are additional links from the CDC you can follow to read about those new MULTIPLEXED METHODS (testing for more than one kind of virus at a time, from a single swab). There are pages of information about the new tests that have been developed and submitted for review and approval over the prior 15-18 months.

As stated numerous times on this thread, the PCR Covid test, the CDC 2019-nCoV RT-PCR, they have been using originally under EUA, which is what they are terminating on 12/31/2021, was a Covid-only test that could not detect the Flu.

The CDC are just trying to cover their butts, the problem with what they are doing here will not fly as most of us knew this back in 2020 and doctors did not seem to care if someone had the flu and later died from the flu from the lack of proper care they labeled it covid-19 and got paid for it too.

Obviously what most people knew was wrong as this incorrect reporting resurfaces every few weeks.

OK, everyone gets that, stick a fork in it. So why is the CDC still blathering on about the flu and the test? Why even get rid of the test? That would be like Pfizer getting rid of all their still EUA Biontech jabs and giving us the fully approved Comirnaty jabs. Why waste ALL those good tests and super jabs? :whistle:

The CDC came out with the 85% false positives figure and it was because of the number of cycles they ran the tests through.

The PCR test was not designed to test for the flu, I agree. The point is it could not differentiate between the flu and covid.

I guess we can just agree to disagree.
Please post your sources that say the CDC had an 85% false positive rate. Because I can't find it.
And also please post your sources that say PCR Test mix up Covid and Flu. Lots of posters have posted that it is impossible for that to happen.

So back to problems with kits giving false positives.
Found a reference that the very earliest of kits had problems
Report Says CDC’s First COVID Tests had Design Flaw

Again Buzzfeed
The Government Asked Us Not To Release Records From The CDC’s First Failed COVID Test. Here They Are.
Reported problems with early tests

It was when people were racing to get things done, when they were being overwhelmed by Covid Cases, right at the beginning of the Pandemic. The early kits had problems, and some of the reagents were allowed to mix prior to the test being used, and so gave false positives. Also people were not careful about cross contamination, and some test showed false positives as a result. But all of these problems were fixed early in 2020, which is right at the beginning of the Pandemic. Once people realised they had a problem, they fixed it straightaway.

Saying now that tests give lots of false positives, is a lie. Early days yes. Now No.

Tests now are more likely to give a false negative (say you do not have Covid when you do) than give a false positive (say you do have Covid when you don't).

Multiple posters have said again and again, that the PCR tests ONLY tests for Covid. The new test that the CDC is replacing the PCR test with does test for multiple viruses. It is better for the patient to have only one nasal swab for mutiple viruses, than multiple swabs to test for each individual virus

And a PCR test is more likely to give a false negative (say you do not have Covid when you do) than give a false positive (say you do have Covid when you don't).

There are several new tests approved by the CDC. Some are multiplex, some are Covid-only. The labs get to choose which ones they will offer. There is not just one the CDC says you must use.

I am not going to go try to find references that have probably been deleted.

You believe what you want o, the official narratice, the government is trying to help.

Many remember it the way I do and I am sure there are references in the forum

Look at what and who are being censored. There is a reason for that.

What do anti-vaxers stand to.gain?

There is no political agenda be ause Trump backs the vax.

There have been lies from the people wanting to promote this shamdemic, there have been protocols put in place to kill people, whether for greed or.agensa, it does not matter.

Cast your seeds of doubt but enough people have seen the evidence before it was.deleted so you job of obsfucation may be difficult.

The evidence of adverse effects.is becoming overwhelming, so much so that soon, all pretense will be dropped and they will only be able.to go.forward.through force.

Once they people are aware that.posion is being forced on them, what do you think the reaction will be?

What do pro-vaxers stand to gain?

Which one of the genetic markers that it tests for is found ONLY in covid-19?

They gave them almost a year notice to use those tests and transition to approved kits. It's the exact same for comirnaty...use the eua approved vaccine and transition to fda approved comirnaty. It's not a hard concept.

It's not one target only.

It's usually 3. One for nucleocapsid (N), envelope (E) and spike (S) portions of the virus. If all 3 are positive it tells you that the whole virus particle is present. The vaccine does not effect results. Omicron has enough mutation in the spike protein that it will not be positive so general practice now is if N and E are positive and patient clinically presents with symptoms consistent with covid they will be treated as positive.

It's called S region dropout.

The Pandemic has only been around for almost two years. There are quite a lot of people who would be pleased if things they posted no longer existed after two years.

As far as I am concerned everything stays on the internet forever. It can take some work to find it, but it is usually there. The earliest sources I found on PCR testing are May 6th 2020. Maybe other stuff, but I have not found it.


As an aside, here is a story from "The Irish times" on Cattle dated 4th Jan 2020 Cattle return to Dublin’s suburbs

So if there is plenty more stuff out there from January 2020, why would your sources have disappeared?

EXCEPT, as has been posted several times, and at least once in response to you, directly - legally, the EUA approved "vax" and the Comirnaty "vax" are NOT the same.

Willfully ignoring this most important and recent legal ruling undermines your credibility.

I see that the word-weasels are hard at work.

WHICH government entity (judicial versus executive) has the final authority on this matter, at this time? <rhetorical>

Answer: Federal court (at the moment) trumps FDA authorization interpretation.

Realy, you are asking why things disappear? From Twitter, farcebook, youtube?

Their is nothing to really talk about.

Try reading the corona thread on the forum!
For example the lasr of 1483 pages

Word weasels...you realize that the judge DENIED the injunction requested by the folks protesting the DoD mandate? The case doesn't have any bearing on whether the 2 are equivalent or not. You take a comment in a opinion on a motion that went against your assertion in a case not even dockets until September of next year.

Is there another ruling or prescedent that applies to your claims?

Courts may have the final word, but according to the article you link to thats far from being settled:

Despite the federal judge’s opinion in Doe et al. v. Austin, no court has yet issued a final, definitive ruling that an institution may not mandate a COVID EUA product.

Some courts, most notably in Bridges et al. v. Houston Methodist Hospital, have upheld EUA mandates for employees in a case where 116 hospital employees filed a lawsuit disputing their employer’s vaccine mandate on the grounds the vaccines were being administered under an EUA.

This decision was appealed to the U.S. Court of Appeals for the 5th Circuit, and a decision is far from final.


And the Judge in the article you cited didn't even issue a preliminary injunction. He denied it.

So until something else occurs, the FDA position stands. the vaccines are interchangeable.

Nope. The older pcr does not test for the flu at all. It cannot give a positive covid pcr test. The pcr tests for 3 targets that are only found on covid. It is highly specific to that virus. Positive for flu cannot cause a positive covid test.

It is for this reason that people are ALSO tested for influenza.

I have been tested for the rona over a dozen times, never once was there a flu test in conjunction with the rona test.
It seems the reason for so many rona positives was more about cycle counts used.
