Can type A blood be transfused to A recipent?

Answer 1

No, your blood type is your blood type for your entire life span. Your blood type also affects your organs etc should a transplant be needed. You also could never get a transfusion of blood that does not match your own. It could lead to severe complications and even death.

The only change to bloodtype that can occur is a switch from Negative (-) blood to Positive (+) blood. This is due to the development of antibodies to the + bloodtype. This process cannot be reversed however, going from Positive (+) to Negative (-).

The process is most common in pregnant women or new mothers, when the fetus carries Positive, and the mother Negative. In the event the baby carries Negative, and the mother carries Positive, a medical injection is required to prevent the mother's immune system from attacking the fetus.

*** Update from different member***

While the information provided above regarding the rh factor is somewhat correct, it is irrelevant, as this was not the question. Obviously, the answer is not an unequivical "No", as there are numerous people here (including myself) who are living proof that it is somehow possible. Someone very recently posted a lengthy reply that seems very interesting, but as it doesn't appear here, it is nigh unreadable. If the poster is you, please repost by improving this answer and/or post a link to the original research. I think we all are very interested in reading more... Thank you... Xcuzeyou

i was born with A+ blood, 18 years later i come to find that i now have RH negative blood

*** Update ***

Your blood can change type, and not simply the Rh group. If a person receives bone marrow from someone who is a different ABO type "assuming the marrow is compatible" (eg, a type A patient receives a type O bone marrow), the patient's blood type will eventually convert to the donor's type.

Another example is Demi-Less Brennan who's blood type changed after a liver transplant in addition to adopting the same immune system as her donor, effectively ending her rejection of the transplanted liver.

I was typed at birth as A+, just like my mother. Somewhere between 18 and 19 I was typed as O -, just as my grandfather. When I inquired to the Red Cross as to how my blood type could have changed, they told me that quite often at birth you still have enough mother blood running through you that you are typed same as mother (as I was), but later in life may be typed differently. Thank God I was typed same as my Grandfather, universal donor. My mother, an RN, still doesn't believe my blood type is correct.

*****Update*****

If everyone would get their mother's type when born, in your entire family tree there would be just one group. Your lab results probably just came out wrong the first time.

IMPORTANT: Blood does not get transfused between the mother and foetus during or post pregnancy.

Now answering the actual question, NO. Antigen B cannot just be produced in an O type as O type will have the antibodies to destroy them. Hence O becomes the universal donor and AB the recipient.

===additional information===

Not all blood typing results are accurate. Sometimes this is sloppy work or bad record keeping. This happens often, which is why no one would ever give you a transfusion based on what you report as your blood type or what your records may say--they will test again to make sure. This may have happened to you.

The main reason that someone may think his Rh type changes is that he or she may have a variant allele for the Rh-D antigen (the one the test looks for) and the test is not able to detect your "positiveness". You may think you switch from positive to negative but you do not. As long as you have your original bone marrow, it puts the same markers, called antigens, on the surface of each and every one of your red blood cells.

Pregnancy does not change the mother's blood type, even temporarily, although a previous post mentioned that the test may incorrectly detect some fetal antigens, leading to a false result.

Acquiring anti-Rh antibodies does not make you Rh positive. In fact, an Rh-positive person cannot have anti-Rh antibodies or the antibodies would cause agglutination of his red blood cells (a transfusion reaction).

There is a lot of accurate information online about Rh factors that is in scientific journals and written by people who study blood types.

**Personal Update:

When my baby was born her blood type was B+, we repeated the blood test 5 months later and she is now 0+. It is true, the baby carries enough mom's blood that could give a wrongful reading and they do recommend rechecking it after 6 months**

In a way yes, but only if you have AB+ blood and after a transfusion, as your body can contain both AB+ blood and any other blood type, so in that way it's not completely impossible. You could be BOTH AB+ and A+ at the same time for example.

**UPDATE***

I think blood type can change, i am also a living proof that blood type changes as time goes by. When i was 16 i found out that my blood type was O+ and then last month me and my friends went to a blood bank to donate some blood, i was shocked when i fund out that i was an A+. Is it really possible or the nurse just got the wrong results?

**update**

Blood type can and does change. Mine changed twice. From the day I was born to age 30 I was Type O+. It had been checked/documented many times. Then one day day they had a Red Cross blodd drive and they tested me and gave me a donor card. I paid no attention to the card saying I was O-. Several days later I was showing someone my card and noticed it said O-. I immediately contacted the Red Cross so they could discard my blood. I went back a few months later to be retested and they confirmed I was O-. I told them that was impossible but they insisted I was O-. A year later my National Guard unit had a blood drive and I got retested again. This time it came up B+. I showed them my Military Medical records showing me as O+, my I.D./Dog Tags showing O+, my Red Cross donor card showing O-, and now about a year later Red Cross making me a new donor card with B+. They scheduled an appointment for me to go to the nearest Red Cross donation center to be retested and again it came up B+. At that point the Red Cross banned me from donating and I still don't now today what my blood type is. If the Red Cross can't figure it out who can?

Thanks for answering.

I did have several blood test. The last time I got O were the test around 12 yo when I got typhus. Then I got sick by neither thypus or Dengue Fever (doctor cant tell since both my leucosite and trombosite level drop) at 16 yo and get blood test with result of B-I think its a joke so I dont really mind it before-.

My Mom is O and Pap is B. The only operation I got was operation for bone fracture when 20 yo with result still B.

Red Cross never allowed me to donor my blood since I have low blood tension and since I'm kinda afraid to see blood, it got worse.

Answer 2

No. A person's blood type is just a statement of which particular proteins (if any of the particular ones) are in one's blood. For example, the A blood type has the A protein. The B blood type has B. The AB blood type has both A and B. The O blood type has neither A nor B. It is impossible for you to remove all of your A proteins from your blood, so no. You can't change your blood type. However, a person with the A blood type can receiveblood from O blood types, although not vice versa.

Answer 3

yes a person with blood type o can donate his kidney to a b blood type person,but still there is a risk that the kidney might resemble itselfs as antibody so the entire organ would be killed in host body

Answer 4

In the perfect world, no. IA and IB are codominant so both alleles are represented in the person's phenotype. Blood type A can only be represented by itself in a phenotype if the person's genotype is either IA IA or IA i.

(The result of a DNA mutation may be able to create a phenotype of blood type A out of a (purebred) cross (of blood type A and B).
No. IA and IB are both codominant . Blood type A can only be represented by itself in a phenotype if the person's genotype is IAIA or IAi. Blood type B can only be represented by itseft in a phenotype if the person's genotype is IBIB or IBi. If the phenotype (blood type) is AB the genotype is IAIB.

Answer 5

No,

because type A has antigens A and Type O has antibodies for both A and B since it has no antigens present. Type O will reject the type A blood. But, if you rarely have Bombay O (little present of A or B, but dominantly shown as type O), then you are in different case.

Answer 6

No. A person with type A blood may only get a transfusion from a person who is type A or type O. Giving them type B could be fatal, because the blood will clump in their veins and arteries.

You also need to consider the RH type - RH positive can receive positive or negative but RH negative can only receive negative. And, most hospitals will cross and type match on several other criteria as well, in order to get the best and safest match.

Answer 7

A Negative is "A Type", and so is A Positive.

Answer 8

Yes, if their rhesus type also match.

Answer 9

No

Answer 10

no
