If one had vaccination and also suspected COVID. Any way to tell if antibodies are due to vaccine or infection?
Labs can identify the difference. Whether they recorded that for you and can give it to you is another story.
You want a rapid antigen test instead to avoid confusion
It was some time ago, I no longer have any symptoms, except my sense of smell is not yet 100% back.
If antibodies are talking in Chinese then it's due to infection, if they're talking in English then due to vaccine, EZ PZ 😂
Made my day
If the test is for spike protein antibodies it could be due to either. If the test is for nucleocapsid or other viral protein antibodies it's only from infection. None of the antibody tests tell you if you currently have virus in your system or not, just presence or absence of antibodies.
The test gives only the total: >2500 U/mL. How likely it's due to vaccine only, if the second shot was about 8 months ago?
Total won't tell you anything - need to know the target of the antibodies being measured. FDA warns against using antibody tests to indicate current infection for a reason - they're not appropriate for that.
Ask Elizabeth Holmes.
There are two types of tests: one for anti spike protein antibodies, this one is generated by the vaccine also. And anti nucleocapside antibodies. These ones are generated only by the viruses as of now, so this is the one you want to test for a previous infection.
Call Labcorp and ask.
