  • Hi Guest - Did you know?
    Hot Topics is a Safe for Work (SFW) forum.

Do you know your blood type?

I have no idea
I assume it is one of the common ones otherwise the Blood Bank Service would be nagging me to donate
 
AB Negative.

Was likely from my maternal line, as the grandmother was O positive (I think), but her husband was Rhesus negativve. I don't know my father's type.

When I began donating blood in 1983, AB Neg was the rarest of the main blood types in the U.S., with only an incidence of 1:167. Current Red Cross data still shows it as the rarest, but at 1%, less for non-Caucasian populations here.

I don't know that it is common to know, but at one time, I think most middle class, educated citizens knew as a simple safety awareness. Current practice is to type blood before transfusing, but in an emergency, one could have a card (which I used to carry) to verify blood type without waiting for a test. In a near-fatal emergency, that probably saved some people over time.

Today's litigious society has probably made that a thing of the past, so I doubt as many people know their types today.
 
Yes. I'm a senior, and back when I was young it was common practice to know your blood type, in the event of an emergency.
 
It’s not that important any more. There’s test that type blood in under a minute so it’s not a life saving measure any longer.
 
wow I used to and realize I have no idea anymore...but they tested and typed it pretty quickly a couple of years ago.

That is why I asked. I knew mine as a kid, but forgot. I donated a couple weeks ago though and they told me.
 
I know I was told what it was, but I don't remember. I may have carried a card at one time with it printed on it.
 
I know mine. I realize it probably seems like nonsense, but there's blood type diet that seems to be credible. Avoiding the ones on my avoid list seemed to help digestion. It's supposed to help with weight loss, but that's not something relevant to me. The [very simplified] idea behind the diet is there being a different immune response to foods and eating the wrong ones keeps your body in a chronic state of stress.
 
I wouldn't have a CLUE !
Given I have endless blood tests for diabetes, liver function tests (over a now cured positive Hepatitis C status) and a three-monthly test as part of our PrEP roll-out.
I'm assuming if I need a transfusion at any time, I'll initially be given the universally compatible type (the name escapes me) till my group is established.

For the major antigen types, that would be O-Negative. The blood would have neither the A or B strain, or the Rhesus factor.

There are hundreds more antigens, but apparently those major types are the ones that would prove fatal if crossed.

All that said, the preference is still to match type exactly when possible.

Quite an interesting article on blood types from 10 years ago

www.bbc.com

Why do we have blood types?

More than a century after their discovery, we still don’t know what blood groups like O, A and B are for. Do they really matter? Carl Zimmer investigates.

What a stellar article. The bit about the Bombay blood type was fascinating. Uusually long articles are simply unfocused and badly edited, but this one seemed worthy of its long content.

The author's premise, that we still don't know what blood types are "for" is a great question. Having just watched War of the Worlds again recently, I have to wonder that the types are not properly attributed as serving a purpose, but evidence of different populations having been selected by evolution as survivors after various plagues that nature has thrown at humans. Maybe different populations survived by having the genetics to do so, and they fathered large swaths of humans after them.

So, now the ABO types are not much more than the evidence of who survived, much like geneticists can today determine if you're descended from Genghis Khan or not. Today, they likely do have relevance to many health aspects, ranging all the way from inherented intelligence to cancer to allergies.
 
This thread had me wondering why we have different blood types, when we’re basically the exact same carbon copy as everyone else.

Thanks for that, dude - though this "match type exactly when possible" doesn't seem high on the priority list by medical authorities.
At least this is how I read it ?
