    seroconversion covid-19 antibody test

    Ellen van Gijsel
    coronavirus testing
    People who already have IgA antibodies but have not yet tested positive for IgG should have a follow-up test after 1–2 weeks to see if seroconversion has occurred.

    Seropositive means that antibodies against COVID-19 have been detected in the blood. This means you have been exposed to the SARS-CoV-2 virus, which causes COVID-19, and that your immune system has produced antibodies against it. You can be seropositive when you currently have an infection, but also when the infection has already resolved.

    When a person has not produced antibodies, this is called seronegative. When a person contracts an infection and starts making antibodies as a result and goes from being seronegative to being seropositive, this is called seroconversion.

    In the case of the new corona virus, it is not yet entirely clear
    • how the conversion proceeds over time
    • if you're immune to covid-19 if you have antibodies.
    • how long you stay immune if you have covid-19 antibodies.

    The IgM antibodies, which it may appear after 10 days, are too similar to other influenza viruses, making this test unreliable to detect COVID-19 antibodies. Therefore, we test IgA antibodies and IgG antibodies with the ELISA blood test, for the highest possible reliability.

    What I don't understand is that individuals who have gone through the infection and can demonstrate that they effectively have that conversion, pointed out by a blood test, that individuals do not get a Covidsafe certificate from the government. Why would you need to be vaccinated if your body has made antibodies of its own. Surely you would think that this is always better than inserting a foreign object into your body ???? Someone please explain that to me. Who says that a person who was vaccinated is also equally protected and protected for as long ???? And infection remains with ANYONE: conversion or not.
