Tested negative for IgG (spike) four months post-J&J vaccination. Any potential explanations (aside from a deficient immune response)? Most explanations I have found have to do with nucleocapsid antibody testing can’t pick up spike protein antibodies Corona Antikörpertest IgG-Spike(not the test used here) or duration after vaccination (it’s been over four months). Thanks!

is that required for your surgery?

It's like reading a post from 3 months back (that I don't understand, still). Thank god we've moved on up here.

Is this the test to see how much of the vaccine you have in your body?

It sounds like the vaccine wore off as all vaccinations explained happen after four months. High/Low IgE levels may mean you are susceptible to allergies, and getting colds easily. There’s not much you can do about it except vitamins, healthy eating, and moderate exercise, the same goals everyone on here is trying to obtain. I see a specialist for asthma/allergy and take the meds they suggest.
