@lez I have shared resources over the last year here in the Covid LC support group to follow and research and for tests that helped to isolate causation. My most resent post was on LAB CORP for the newest isolation testing you can order yourself. Previously I posted a link to testing for the IgG antibodies that flow through you blood stream so doctors can see if it's 'normal': https://healthmatters.io/understand-blood-test-results/sars-cov-2-spike-ab-dilution

In summary, regarding identification of spike protein:
1. The most important isolation testing started with me and that was just a 'fluke'. For 1 year I used a test strip on the drainage from my sinus cavities which began within 2 mos of first Covid vaccine. Everyday the drainage tested POSITIVE; even after a full year! This issue scared me: 'positive'? I was told I could not spread the virus even with this positive test because it was either revealing I had the antigens after the vaccine or I had antibodies from a 2020 Covid infection per the doctors.
2. Isolation for why this was happening and why I continued to have health decline came from my T-Cell panels. I could write a book about T-Cells from this journey. Basically, my 'fighter' T Cells were kicked into overdrive. Timing for my health decline linked this T-Cell overdrive to the vaccine. Once I asked to have my immune system tested, it was revealed that my killer cells were off the charts. This condition is called T-Cell exhaustion. The T-Cell 'sensors' which monitor invasions were continually being alerted that invaders were on the rise. My immune system detectors sent T-Cell 'fighters' to find and 'blow up' the spike proteins. But T-Cells work as a team and there was one T-Cell that was not being produced in my body after the vaccine: CD8 NK. This is the T-Cell that is the 'safety escort out' or 'remover' of debris from a destroyed Covid cell (or any viral or bacteria invasion). So this part of the immune system was dysfunctional; almost non functional. There weren't enough of them to transport the dead spike protein fragments blown apart by the destroyer T-Cells. This meant there was little to no safe 'flushing' or removal through normal process of bodily waste. So, spike protein fragments that had been destroyed were left behind. No transportation exit, they were stored in my sinus cavities (yellow ooze) and later 'stored' in my fat cells and various parts of my body; in my gut, likely my muscles and in my liver. Looking back 3 years, without doctors understanding what they were seeing, when I would go for my annual physical after the vaccine I suddenly began to have 'white cells' in my urine when in the past my urine was always clear. I had a history of kidney stones so this was a path they followed for year, but the kidneys were clear and I kept testing positive for white blood cells in the urine.

There were 'additional tests that involved the gut (more blood work, liver imaging, fibroscan) but that is another aspect of this journey as it relates to how the spike fragments have remained in my gut once they drained into my throat from the sinuses. Humans all release 2 pints of brain liquid debris directly into the sphenoid each day. Mucus drains, entering the stomach (some people spit it up but when you sleep it just drains quietly). By this time my microbiome system was totally trashed so depositing spike protein fragments in my gut made it worse. As I mentioned, I did not know at this point it was likely I had C-Diff from all the previous anti fungal and antibiotics I had been given for 1 1/2 years.

I posted this in one of my previous posts in the group: 2 doctors in California that work in research made a discovery that there were 65 totally different 'fragment' spike proteins being found stored all over human beings bodies of LC sufferers. It takes a special test, it costs $2,000+ to find these spike protein fragments in humans and insurance does not cover it and you can only get it in places like research labs. So it was unlikely there would be 65 different solutions to seek out and find and remove them safely from my body.

3. I traveled the more obvious path of working to restore my bodies ability to make more CD8 NK cells in hopes I could begin to 'remove' spike protein fragments destroying my body. Local doctors rarely know solutions or for that matter did they have a patient with LC; so I selected a natural path to assist. I took a study with me from a European lab that had 'isolated' the spike protein fragments and I was told, I had been having an allergic reaction to the spike protein and its related fragments left in fat cells and not being 'cleared' out; it was an event that began with the vaccine based on my extensive time line documentation. Glutathione was recommended. I wrote about glutathione benefits in other posts. There are also naturopathic options for direct NK cell improvements.

I hope this provides assistance for you when having discussions with your doctor. If you are up for many days of 'technical reading' this link was exhaustive but it did open my mind to 'options' and to a better understanding of Long Covid: https://www.nature.com/articles/s41586-023-06651-y_reference.pdf

@lez This is the medical journal paper from Dr. Stringer on the findings for 65 different spike protein fragments as of Aug 2025. Nothing published since last summer and I don't know if they lost their funding for this research:
Summary:
"This raises the question: is this just continuing to take out the trash from the COVID infected cell or is this really ongoing replication someplace? I think that's the mechanistic issue that needs to be resolved in future studies."
