What is your blood type, and how do you know?

A positive. They’ll tell you if you give blood.

A+

I know from donating blood and a kidney.

You don’t need to know your blood type. If you have a medical problem they’ll figure it out fast enough.

HOWEVER I encourage everyone to donate blood. It’s an easy way to volunteer to help your community.

Multiple surgeries and a blood disorder (and endless testing involved) and somehow still have no idea what my blood type is. I bought a cheap kit off of Amazon and plan to check it out someday, but waiting till my niece and nephew are around so they can be nerdy with me :)

I’m either A+ or B+, but I don’t remember. I tested it myself, in a lab, but then forgot.

There are several reasons it is important for everyone to know their blood type. The most important reason is if one ends up in the emergency room and needs a transfusion. It takes time to run a test to find out. Some blood types are incompatible with others, and if mixed, can cause blood clots. Other reasons include health risks that are more likely by blood type.

I’m O negative, or universal donor. This means that if someone needs a transfusion and their blood type isn’t known, the doctors will use O negative type blood, as it is compatible with every blood type.

A* It is good to know your blood type.

Giving blood in 1972 and getting donors’ card.

O+ . I have known for as long as I can remember, because my mom is O -, and they were worried about rH complications when I was born.

O neg, Universal donor. I really should donate blood more often. Thanks for reminding me. GQ!

The red type. I saw it a few times.

I’m ABO type A and Rh negative. I know because I’ve given blood and I use to work in a blood bank as a med tech. Also “A Neg” was written on my Army dog tags.

Perhaps your baby sister has a very rare blood type. Or she may have been in danger of developing hemolytic new born condition (there are several types). In such conditions bilirubin (a byproduct of lysed RBC’s) can build up in concentrations high enough to cause brain damage to the baby. If the bilirubin rises to a level over 20mg/dL then a transfusion may be considered.

FYI only 7% of the population has my blood type (A Neg). So If I need blood I can only safely receive A Neg or O Neg blood.

I don’t know. Also, I can’t give blood due to an incurable illness I have.

A+. I found out when I was pregnant.

A+. I know from receiving blood. Thank you, those of you who donate!

O neg. I have donated literally gallons.

Donate some blood, @Dutchess_III. They’ll tell you what type you are, you’ll do a good thing, and you’ll get cookies.

O+. I attempted to give blood for the first time when I was 17. Someone fucked up in the lab and false-positive tested me for Hepatitis. I got a letter that mentioned my blood type and informed me that due to that person’s screw up, I could no longer donate blood.

Since O blood can only receive O blood, I am still very bitter about this, since I cannot pay back the blood I needed when I required two blood transfusions after childbirth.

A+ I donate blood regularly.

O+

I’ve known since I was little due to having anemia.

O+

You read the specs in the manual that comes with products you buy.

I consider my body the same way.

I’ve also donated blood for decades. My blood type is the same every time. OMG!

O- with the RH factor.
Yep, like @gorillapaws us O- types are universal donors and I have given a lot of blood over the years but not in the last couple now since I moved to a new area.
I used to donate at Stem express and they send blood, plasma and bone marrow all over the world for various research and medical studies. Super cool stuff they do.

Wow….there are 4 of us O- types here out of a cross section of only 12 that know their blood type. Interesting, it’s a small world indeed.

O positive. It says so on my dog tags.

@Coloma I thought the RH factor is the same thing as the + or – in your blood type? What does O- with the RH factor mean?

@Mariah Yeah, my mistake. Not awake yet. haha

I am O negative. I have always known this, just because I have really. I also give blood.

It is universal. Anyone can receive this blood, but I can only receive my own type.

@LBM Wow… another O- we should start a club. haha

@Coloma in the UK it seems to be quite rare, but it looks like a ‘popular’ blood group on here.

@LBM Its rare, worldwide, and only 9% in the U.S. have O neg.

@Coloma Must be a Fluther thing.

I was just wondering whether anyone has ever studied a correlation between intelligence or analytical capacity relative to blood type.

Because Fluther has a LOT of O compared to population.

That assumes Fluther is of above average intelligence. O+ is the most common blood type. The RH negative types are the rarest

One oddity for me, when I was younger my rh factor was reported to be negative when donating blood and more than once. Now it’s rh+ everytime. Anyone know what would cause an rh factor to switch? I just figured they changed the way it was classified sometime in the 90’s

I have a feeling I am not O-...... :( Now I’m offended.

We also have loads of INTJs here.

I’m intj also. We seem to have a lot of firefly fans too.

I use to know my HLA type when I was donating platelets using aphersis 30 years ago.

This turned into quite the conversation! I need to ask more questions when I’m drinking rum and Diet Coke.

Also INTJ.

I love correlations. ^_^

@ARE_you_kidding_me – after a quick search, it appears there are two types of Rhesus antigens, D and Du. Du is considerably weaker, and many times won’t show up on a “normal” Rhesus antigen test.

So you might be RHo(Du) rather than RHo(D).

@Tropical_Willie: I did a boatload of apherisis as well. I always requested the one-armed machine because my nose would itch EVERY TIME. I think it was psychosomatic. ;-)

@Seek that was my assumption as well. I figure they test for it a little better now.

I’m an NT too, but an ENTP. Interesting, the more rare blood types and the NT correlation.
I get along best with NT types in real life too. haha

OK, how the hell can I find out what ANPT I am?

Dutchess_III Look up Myers-Briggs or MBTI, you should be able to take a test online.

@Dutchess_III Take the results with a grain of salt but the INTJ correlation here is a little hard to ignore.

ESTJ

ESTJs make up about 7% of the population.

Decisive, efficient, and systematic.
Dedicated and responsible
Strong-willed
Natural leaders
Organized and reliable
Value tradition and stability
Committed, trustworthy, and honest
Enthusiastic, outgoing, and friendly

Which test did you take?

I only ask because most of my friends are ENTP – to the point where it’s rather scary. I assumed you were as well, @Dutchess_III

Here.

Damn. Wrong blood type, wrong personality type….more and more sure I don’t belong here!

O – and ESFJ. I know my blood type because I have donated blood. I should do it more.

Damn, 5 of us now out of 23–24. That’s a pretty high percentage for such a small group.

FWIW, my husband is O – and INFP.

I was identified as B Rh negative when I gave blood.

A+, found out when I enlisted in 1967.

B+ We did blood typing for each student in my 10th grade biology class.

@Seek: Is there a reason you can’t donate now? You can get retested (some states are happy to do this, the eligible donor list seems to be shrinking) and donate now unless there are other reasons preventing you.
A screwed up lab test from a number of years ago shouldn’t prevent you from donating now. I would also be frustrated.

I tried a couple of years ago. Still blacklisted.

That’s too bad. I’m surprised they didn’t retest.

I glanced through the thread…why aren’t you allowed to give blood, @Seek?

I had a false-positive test for hepatitis.
