    I have a family member who falls into the immunosuppressed category and wants to get an antibody test once fully vaccinated. I know that antibodies are only one part of measuring the vaccine, but waned to know if anybody has taken these type of tests and how are they reported?

    I had an antibodies test last week. It's a blood test. They measure the antibodies in units per ml. The readable range is from 4 u/ml to 2500 u/ml. Mine was 2500. The higher the better. I've had covid and a first vaccine shot, so I was expecting it to be high.

    When you want to do an antibody test to determine the effectiveness of the vaccination, it's important to tell the lab that this is your intention.


    After a Coronavirus infection, there are antibodies against the spike protein, and antibodies against the nucleocapsid.

    After a Coronavirus vaccination, there are antibodies against the spike protein.


    Meaning, if a lab does an antibody test for the nucleocapsid, it may come out negative, even if the vaccination successfully produced antibodies.
