IgM and IgG antibody test for Covid

YSI
'IgM levels do wane earlier than IgG' according to the CDC website.  This might explain why my IgM was positive and my IgG was negative-my initial untested illness was almost a year ago.

When they run this antibody test, advertised as a Covid test, does that mean they specifically identified Covid-only antibodies, out of the soup of many other different infections that also might test positive for antibodies? I ask because I did not bother with healthcare at the time of my illness which could have been multiple different viruses besides Covid.

I am really noticing the long-term side effects of my infection from last March. Mental fog-unable to do math calculations I used to be able to do in my sleep lol, and a general fatigue, plus bizarre pounding pulse episodes, which only occur very sporadically without exertion and end quickly, while sitting in my recliner! Also momentary fevers/chills also very sporadically, and rather routine expulsions of green byproduct. I clearly have an ongoing infection of some kind-does Covid leave behind unhealed sores in areas not visible to us?

IgM antibodies develop when an infection is new, really generally speaking. Typically, they wane as IgG antibodies develop, and this can vary a bit from infection to infection. IgM antibodies are your body's first protection against an antigen.

IgG antibodies then develop, and this varies from infection to infection, and from person to person. This is what remains for a certain period of tiime (again, varies from infection to infection - covid antibodies don't remain forever, but something like herpes antibodies remain for life, as that's a lifelong infection).

Covid can leave organ damage, mood issues, fatigue issues, and we still don't know the reasons for all of it yet.

Have you seen your doctor? You can sit and wonder and ask all the questions, but you could also have something else going on, too, and need to get checked out.

Look into what's colloquially called the "long hauler" effects of covid.  Because it affects so many different organs and processes in the body, along with clotting and a very powerful immune system response that is too strong, many people who have had it have many long-term symptoms.  Nobody knows if any are permanent or not, as the virus hasn't been with us long enough to know.  Some are quite severe, and some are not.  You might want to look into old video if it exists of CNN anchor Chris Cuomo, who continued to broadcast while he had covid from isolation in his basement.  He has kept up a regular review of his long-term problems, including depression, which he never had before.  He's a pretty good source because he comes from a well-connected political family and Dr. Fauci is a personal friend of that family, as well as a close relationship with Sanjay Gupta, CNN medical reporter and a neurosurgeon who has been reporting on covid since the beginning.  Your case was obviously on the milder side, and so any long-term effects are probably also going to be on the milder side if reports are accurate, but this is one of the reasons those who have been minimizing covid because it really is seldom fatal -- no consolation to all those dead people, of course -- it isn't something to fool around with because we just don't know a lot about it.  Now, I'm not sure if your test is definitive that you had covid or not -- not qualified to say -- and just because you have some things going on doesn't mean even if you had it it's the known cause.  We're in the realm of possibility here, as you didn't get treatment or diagnosis at the time, as few did as we were all told if it's mild, stay home so you don't infect anyone else or burden hospitals.  But you know, you know yourself better than anyone else and know what you're feeling.  Peace.
