Antibody Testing Is Not Currently Recommended to Assess Immunity After COVID-19 Vaccination: FDA Safety Communication
FDA Division of Industry and Consumer Education ^ | May 19, 2021 | Un-named FDA (DICE)

Posted on 09/20/2021 1:28:39 AM PDT by Grandpa Drudge

The U.S. Food and Drug Administration (FDA) is reminding the public and health care providers that results from currently authorized SARS-CoV-2 antibody tests should not be used to evaluate a person’s level of immunity or protection from COVID-19 at any time, and especially after the person received a COVID-19 vaccination.

They are doing this solely to reduce legal liability to the vaccine mandate.

Have any Democrat leaders died from Covid? I think they are taking the “real”, effective vax. The secret one.

They are trying to kill us. Easier to rule everyone if the rebels are out of the equation.

Discrete Immune Response Signature to SARS-CoV-2 mRNA Vaccination Versus Infection

From the abstract: While both infection and vaccination induced robust innate and adaptive immune responses, our analysis revealed significant qualitative differences between the two types of immune challenges. In COVID-19 patients, immune responses were characterized by a highly augmented interferon response which was largely absent in vaccine recipients.

The paper is available at SSRN: https://ssrn.com/abstract=3838993 or http://dx.doi.org/10.2139/ssrn.3838993

The indication is that naturally acquired immunity (antibodies) are broader spectrum, providing better immunity against variants than the vaccines, beecause they target other aspects of the virus in addition to the spike protein.

I have as much faith and trust in our Public Health leaders and elites as I do our Executive, Military, Foreign Policy, and Intelligence leaders and elites who recently brought us the Fall of Kabul.

I hope that puts it in perspective.

That’s what I’ve been reading, too. Natural immunity produces a protection far better than any of the ‘EXPERIMENTAL” vaccines.

This is not well thought-out.

You could have zero antibodies for any particular disease and still have good immunity. The presence and or quantity of antibodies is not the determinant.

The memory cells of a body that have been sensitized to a disease and immediately will begin to produce antibodies if there is an infection with that disease is the mechanism of immune response. The antibodies will not be there until they are produced.

Cells in the body are dying and being replaced and this is true of antibodies as well. If the antibodies that you formed to defend against every infection you ever encounter in your life hung around throughout your life they would fill all of your blood vessels and there would be no room for blood.

right. I saw that. I still think that a test lab is official enough to be able to hand out immunity cards just like a vaccine card, and for that to be accepted the same way. With an immunity card, you’d even have a paper trail with the actual test results. Other than the card, no papertrail with vaccines. So I dont’ see why that would be a problem.

Are those the same test they use to see if the vaccines are working?

No, they are not. And the answer is actually pretty complicated, but I just went through an unsuccessful effort to get the right test from LabCorp (where I have standing orders to monitor one of my heart condition medications).

I am extremely reluctant to accept the mRNA vaccine, specifically because one of the reported adverse reactions are directly related to my "co-morbidity" condition.

What follows is copied from my detailed communication with LabCorp, explaining my problem. It was a lot of work, so I'll just copy it here.

The current fact is that in the past 15 months on 2 occasions I have experienced symptoms that MIGHT have been Covid-19, (but different and less serious than my previous bouts with the flu) and would really desire a reliable test to see if I have natural antibodies to Covid-19.

Find Out If You’ve Had COVID-19 Through an Antibody Test

https://www.labcorp.com/coronavirus-disease-covid-19/individuals/antibody-test

Open that link and
Go Through Labcorp.com to Request a Test
GET STARTED: Request through Labcorp.com
Learn About the Test

So I ordered it, and got a test

1: I understand from a Consumer Labs review that labcorp offers the Abbot SARS-CoV-2 IgG nucleocapsid 100% sensitive 99.6% specific or the Roche Elecsys Anti-SARS-CoV-2 IgG nucleocapsid 100% sensitive 99.8% specific. I assume either one of these may be the labcorp SARS-CoV-2 Antibodies, Nucleocapsid 164068, which is really the test I expected to receive in accordance with the description shown above. Specifically, that “If you have been exposed to the virus that causes COVID-19, your body typically produces antibodies as part of the immune response to the virus.”

2: It turns out that the test I got was labcorp test number 164090, which specifically tests for antibodies to the spike protein produced by the vaccine, which I do not have, as I have not been (nor plan to be) vaccinated. It also comes with a specific disclaimer, as follows:
“Values generated with this assay cannot be used to determine whether or not an individual has developed protective immunity against infection and cannot be directly compared to other assays until a universal standard is established for assay calibration.”

3: It is therefore clear that this test (164090) is not appropriate for the purposes stated above

The intended use of 164090 is: “Semi-quantitative detection of high affinity antibodies to the receptor binding domain (RBD) of the spike (S) protein of SARS-CoV-2. Intended for use as an aid in identifying individuals with an adaptive immune response to SARS-CoV-2 indicating recent or prior infection. This assay also can be used to detect antibody responses induced by currently available SARS-CoV-2 vaccines.”
Additional limitations of 164090 is:
“Values generated with this assay cannot be used to determine whether or not an individual has developed protective immunity against infection and cannot be directly compared to other assays until a universal standard is established for assay calibration. Results from this test should not be used as the sole basis to diagnose or exclude active SARS-CoV-2 infection”

I actually need labcorp test 164068, which should properly answer the above stated purpose for getting this test.

The intended use of 164068 is:
“Qualitative detection of high affinity antibodies to the nucleocapsid (N) protein of SARS-CoV-2. Intended for use as an aid in identifying individuals with an adaptive immune response to SARS-CoV-2 indicating recent or prior infection. This assay can be used to differentiate between antibodies elicited due to natural infection versus vaccination.” Additional limitations of 164068 is:
“This assay will not detect antibodies elicited by currently available SARS-CoV-2 vaccines.”

I requested LabCorp provide this more appropriate test (164068) for my needs.

LabCorp responded that 164068 could only be ordered by doctors, and could not accept an order from individuals. The only Covid-19 test available for individuals to order was #164090 (Which is actually intended to measure the effectiveness of antibodies to the vaccine generated Spike(S) protein.

And never mind that 164090 actually does NOT provide testing for previous infection, as advertised.

COVID-19 Serology (Antibody) Test

https://www.labcorp.com/coronavirus-disease-covid-19/providers/antibody-test

What does Labcorp offer for COVID-19 antibody testing?

Labcorp offers testing for antibodies against either the spike (S) or nucleocapsid (N) proteins of the SARS-CoV-2 virus.

What is the difference in the spike and nucleocapsid proteins?

Antibodies against the SARS-CoV-2 viral spike protein have been shown to have neutralizing effects.1-3 Current vaccines have been developed to elicit antibodies to the spike protein. Labcorp offers both semi-quantitative and qualitative options for testing for spike protein antibodies.

Use our test selection guide for physicians to understand which test to order for your patient.

Who can be tested?

Those who have previously been actively infected by the SARS-CoV-2 virus and do not currently have symptoms or have received a vaccine for COVID-19.

Labcorp Test Number
• Physicians can order SARS-CoV-2 Semi-Quantitative Total Antibody 164090
o Values generated with this assay cannot be used to determine whether or not an individual has developed protective immunity against infection and cannot be directly compared to other assays until a universal standard is established for assay calibration.

• Physicians can order SARS-CoV-2 Antibodies, Nucleocapsid 164068
o This assay will not detect antibodies elicited by currently available SARS-CoV-2 vaccines.

• Physicians can order SARS-CoV-2 Antibody, IgG, Spike 164055

• Physicians can order SARS-CoV-2 Antibody, IgM, Spike 164034

describes 4 different Labcorp tests
SARS-CoV-2 Semi-Quantitative Total Antibody 164090
SARS-CoV-2 Antibodies, Nucleocapsid* 164068
SARS-CoV-2 Antibodies, IgG, Spike* 164055
SARS-CoV-2 Antibody, IgM, Spike 164034

Three of these tests focus on antibodies to the spike protein. (164090, 164055, and 164034)

Only one focuses on the nucleocapsid protein of the actual Covid-19 virus vs those generated by the vaccine. It is also the most accurate and reliable of all the tests. (164068) It’s also the only test (of the 4) designed to detect to the antibodies produced in response to an actual covid-19 infection.

Also, since I do NOT expect to ever get the presently available vaccines (I really don’t trust them) I prefer the most reliable test that will not be colored with results expected from the current vaccines.

video explanation of differences

https://www.brainshark.com/1/player/labcorp?dm=5&nrs=1&sfsess=%7B!$Api.Session_ID%7D&sfurl=%7B!$Api.Partner_Server_URL_350%7D&fb=0&r3f1=09334d1e121f4755054f2c4e440e0d1f19454a2b17090d0152&custom=semi-quantitative_testing

Finally, note in that video that the focus is ONLY on the 164090 Spike protein test (vaccine generated) and glosses over and ignores 164068, the ONLY test for infection generated antibodies.

It is becoming painfully clear the entire pharmaceutical industry is cooperating to maintain this pandemic. I think that (appears to be) criminal.

How can we correct that problem? I'm usually very calm, but I worry a lot about this.

"You don't need to test to see if it's working."

>My first and most obvious conclusion is that the FDA is deliberately preventing all of us from finding out and proving that we don’t need the vaccine because we already have strong immunity to Covid-19 (better than that provided by the vaccine) as a result of recovery from a previous infection.

Bingo. The push only works if
a) they throw out all known immunology and pretend that previous infection isn’t the best protection — asked point blank on the topic, Fauci ducked; and
b) for those people who refuse to forget, they stop anyone from finding out in the same way they stopped people from getting inexpensive, viable treatment.

Once all other and better alternatives are forbidden and unknowable, all that remains is the jab they’ve assigned to everyone (but them).

No, you wouldn’t need an “Immunity card”. The lab test provides a document that identifies you and the specific test results. Its on line, and may be printed, and remains online with secure account password protection for proof if needed.

I must protest!

Immunity cards for "Covid-19" are no more appropriate than for any other common afflictions such as influenza, pneumonia, or the common cold. Precisely because the vaccine is certainly NOT appropriate for everyone, for a multitude of reasons.

Immunity cards are simply an extension of power hungry government tyranny, and are NOT acceptable in a free country.

I had a bunch of blood tests by my doctor as part of my 5 year “annual” check-up in the beginning of August. I asked they include the covid anti-bodies test.

It came back i had almost twice the amount of anti-bodies necessary to produce a positive result. You need 1.4 for a positive test, mine was 2.6 (H), the H meaning High. The doctor could not believe i did not get vaccinated. I may have had covid in March, 2020, but when i got tested back then it came back negative.
