In Certain Rare Circumstances Your Blood Type Can Change

ay receive blood transfusions from a donor with O-negative blood, sometimes referred to as the "universal donor" type of blood.

"An AB patient may receive enough O blood units during a transfusion that nearly all of their red cells type as group O," Our Blood Institute explains. "Within a few months, the patient’s bone marrow should naturally replace the transfused blood with his or her original blood type."

This brings us neatly to bone marrow transplants. Red blood cells are made in your bone marrow, and if you receive a bone marrow transplant from a donor of a different type, your own blood type will change. This, of course, has practical implications for your medical care.

"If you received stem cells from a donor, your donor may have a different blood type than yours," Michigan Medicine explains. "A blood bank technician will provide you with a blood ID card with your current blood type and donor’s blood type. To assess changing of blood type, we will do frequent blood-type tests during your stay. This will help you to prepare for future transfusions. It will take approximately one year for your blood type to convert."

It is also possible, though rarer, to temporarily appear to have a different blood type as the result of a bacterial infection. Known as the "acquired B phenomenon", it only affects people with blood type A, and usually in patients with sepsis, colon cancer, or bowel obstruction.

"The acquired B antigen is a special situation that occurs when a group A patient during an episode of infection when certain gram-negative bacteria secrete enzymes that can modify the A antigen on the RBC surface, which is N-acetyl-D-galactosamine to D-galactosamine that resembles D-galactose (the B antigen) and will cross-react with anti-B reagents," a review of typing discrepancies explains. "This phenomenon will resolve once the patient recovers."

So while most of you will have the same blood type for your whole life, it's possible, in certain circumstances, for your blood type to change. Fortunately, your blood type can quickly be determined by a simple blood test.

At some point in your life you have probably learned your blood type, before forgetting it and guessing the most-common blood group (O). But even if you know your blood type, in very rare cases it can change.

Sometimes, the change can be temporary. People with rare blood types may receive blood transfusions from a donor with O-negative blood, sometimes referred to as the "universal donor" type of blood.

"An AB patient may receive enough O blood units during a transfusion that nearly all of their red cells type as group O," Our Blood Institute explains. "Within a few months, the patient’s bone marrow should naturally replace the transfused blood with his or her original blood type."

It’s why I don’t donate blood. Society should only have one of me running around.

Why not? Our genders can change. Hell, our race can change, even with no physical changes (just check a different box).

I’ve always wondered about if a man gets a transfusion from a woman with a lot of hormones in it.......

That is one of the reasons that when I have surgery I bank my blood ahead of time.

You mean that you can’t identify as the type you want?

Did any want to become dogs or cats?

Time for a Foreign Culture lesson on the Asian Cultures that eat cats and dogs.

Complete with meal preparation, from the beginning.

See if those cats still want to use the sand box at the back of the classroom.

I had an allo bone marrow transplant. Meaning from a donor who was my sister. Not only will the blood type change, but, the entire blood dna. I now have my sister’s dna .

If a a female gets a bone marrow transplant from a omale. Her blood will change from XX to XY.

A bloodtransfusion will not change blood types.

It is not a permanent change. Only a transplant from donor stem cells/bone marrow after killing the bone marrow via chemo (and/or radiation) will change the blood type/dna.

That could be a real bitch for a month or so.

But the effect would certainly fade out by the next full moon.

Cats and horses here. Horses are good eating too. I am aware of some relatively nearby schools with some pretending to be other things but just animals around here. Ive heard of some places elsewhere that also have various demi-human/humanoid beings.

White liberal single parent households.

WTF is going on in there?

This article contains some misinformation. It refers to a “bone marrow transplant,” but this is not what is commonly done. A blood stem cell donor with matching HLA-type markers is stimulated to produce excess stem cells removed from the blood using a filter device (apheresis). The recipient is conditioned with chemotherapy to kill most of their stem cells before being infused with the donor stem cells. They can have a mix of both types (chimera) for a while until the donor cells dominate. Although the blood types can differ, the HLA matching is critical to avoid Graph vs. Host disease (GVHD).
What’s remarkable is that the donor and patient can be different genders. The patient’s blood DNA becomes the donor’s gender. Might make an interesting crime show twist.

OK, you just triggered a memory.

Back in Grade School, about 4th and 5th grade, probably late ‘50s, the girls all wanted to read the horse stories in the Grade School library. The LIKED horses. They probably would have been bait for today’s ‘trans to an animal’ emphasis.

I will say, none of them ever became horses, but some looked really good with Pony Tails.

Friend had stem cell transplant and changed blood type. Not a zero sum phenomenon.

Painful and difficult.

With residual lung problems. Frankly I would have thought similar blood types would have been paramount in stem cell matching.

What happens if you’re in an accident and the ER quickly tests for blood type without knowing anything about the wacky stuff and gives you a transfusion for what it tests at? Does the test come back as both? Do you die from the wrong blood type or what?
