>>24882532I have an immunodeficiency, namely a novel form of Immunoglobulin A deficiency. Normally you are born without IgA, but in my case the rest of my immune system attacked the IgA due to an autoimmune condition when I was younger, and now it is destroyed as quickly as my body produces it, to the point that there is no detectable IgA in serum in my blood. Makes me highly vulnerable to respiratory, blood borne and upper GI tract infections, luckily I have a competent immune system otherwise that fights off those infections well enough for now.
I don't say this to milk any shit (no point anyway when anon), I say it because in IgA deficiency cases you cannot undergo immunotherapies involving the donation of IgA rich plasma. Basically, your body sees the IgA as foreign and attacks it, causing sickness at best and anaphylaxis at worse. As such, any plasma used in treatments for other illnesses need to come from other IgA deficient sources. iirc IgA deficiency occurs in between 1/600 and 1/1500 people (I've seen the number jump around a bit, it suffers for the fact that unless you happen to be tested for it a lot of people don't know the source of their persistent infections). Get yourself checked next time you have routine blood tests, because you want it on file that you can't have IgA positive transfusions if so, and also your plasma is in need (if you are otherwise healthy) for infants who are born IgA deficient, as well as others like you.
>tl;dr get yourself checked for shit this is more common than people think
