Why do I seem to do things the hard way


I learned about blood types the hard way today. They gave me between 50 and 100 mls of the wrong blood. Obviously the usual catastophic results didn't occur because I don't get whole blood I get red cells and the problem is in the whole blood part.

Today's lesson is blood types:
Okay it's really simple.... first off lets remember the disclaimer, say it with me," I don't know nothin' about birthin' babies." Now back to our broadcast.......most people are in one of four blood types or groups They are called groups because there are a whole group of things to do with it but we will look after the big part only.

'A' means that you have A type antigens attached to the red cell and antibodies for B in your plasma around the cells. B is the reverse. Still with me. "O" are the heros of the blood transfustion world because they have no antigens on the red cells just A& B antibodies in their soup. AB folks have both kinds of antigens and no antibodies in their soup. There you go. What's that?........why do we need to know this?......... Its obvious isn't it?....No?

Okay I usually get "O" because I only get the red cells as most of the plasma is taken away in processing, leaving cells with no antigens to react with the antibodies in my existing soup. You see my old blood type is B and my new blood type *Rick's type" is A so I guess I have both antibodies floating around waiting for some poor type A or Type B red cells to float by.

It can't be an obvious thing as the nurses thought nothing of giving me type B blood as my chart says my type is B. I said isn't that interesting I ususually get type "O". Anyway 100 mls in or so the nurse quietly stops my transfusion and says we are checking into your second bag for today. You see I ususally get two bags but only one arrived so the lab went looking for a cross matched second bag and the lab tech caught the mistake as we started the first bag. Two new bags arrived both type O and we got going again. The doc on call talked to us later and explained the chart and why it was a dangerous thing but probably not so worring to me. You see if whole blood of A and B mix you get all the wrong antibodies jumping on the other antigens and clots occur killing the host. Worst case.

In my case the B I was given had small amounts of anti bodies for A in it as there was not very much plasma. I'm not producing very much new A red cells with the A antiagen which the aforementioned antiA antibodies would be hunting for. With me so far. On the other side of the blood forest the small amount of B antigen Red cells given me had not much to fear as my old antiB antibodies are few and far between. so if I don't have much Red cells with A on them and I don't have much red cells with B on them. What do I have.

I'm filled with Red cells that are O, from the five or 6 transfusions so far and the red cells have no antigens on them! Wahoo. So where are the A and B antibodies usually associated with type O people??? I guess I didn't get any as there was no plasma to speak of in those transfusions. But why haven't I developed some of my own antiA or B antibodies???

Hello people!!!!! I'm imuno-supressed. I'm not anti anything. I'm not against As or Bs, I'm not against germs, I'm not against bacteria, viruses,molds or spores. In fact if I'm not careful any bioagent you can name can come and live here in my body for free........Including some stray red cells from my old pal type B blood. Now as soon as my new pal Type A blood gets off his ass and starts making more redcells in his image...then we could have some good old imune reactions but not for the time being.

Question: Does all the plasma that is drained away from the whole blood go to TVs?

more later,
Chris

maybe you have a new career as a medical journalist to translate the complex for the rest of us? you must be fairly alert to pay attention to all of that and then be able to get it in writing. hope all is going well. take care.
