What is rh negative

They are Rh-positive. People who don't carry the protein are Rh-negative. When a mother-to-be and father-to-be are not both positive or negative for Rh factor, it's called Rh incompatibility. Rh incompatibility usually isn't a problem if it's the mother's first pregnancy.

That's because the baby's blood does not normally enter the mother's circulatory system during the pregnancy. During the birth, though, the mother's and baby's blood can mix. If this happens, the mother's body recognizes the Rh protein as a foreign substance. It then might begin making antibodies proteins that act as protectors if foreign cells enter the body against the Rh protein.

Rh-negative pregnant women can be exposed to the Rh protein that might cause antibody production in other ways too. These include:. Rh antibodies are harmless until the mother's second or later pregnancies. If she is ever carrying another Rh-positive child, her Rh antibodies will recognize the Rh proteins on the surface of the baby's blood cells as foreign. Her antibodies will pass into the baby's bloodstream and attack those cells.

This can make the baby's red blood cells swell and rupture. That is an extremely smartly written article. Keep this going please, great job! I too am a part of the RH Negative family. I loved reading this article!!

I lol and asked was that a joke because throughout my adult life I had been told I had to be ever so careful due to the small percentage of RH Neg, people out there. I was even told it was smart to store my own blood whenever I knew I would have surgery.

I was given the RhoGAM injections with all 3 pregnancies. None of my children have my blood type…. So tell me again how special Rh Negative people we are, lol.

Great read! Dana, that means you are A-. They never talk about this they just assume the fetus is most likely positive they never talk about the risk of injecting pooled blood from rh positive persons into a mother and child whom are both negative!! The risk of getting this injection and not knowing the child your carryings blood type just assuming seems naive and very dangerous!! Hi Cindy. It would definitely be best to talk to your OBGYN or primary care physician about any issues pertaining to a pregnancy to ensure you have all of the knowledge before making any big decisions.

Stephanie, thank you for sharing your story! My wife is rh positive. Now she is pregnant. In the past she had apportion. She did not injected the injection. The doctor said her bod may or may not prepared antibody. But am afraid what will happen to the baby and my wife. Is there any medical solution to check now? Hi Gina. Thank you for your willingness to donate! Hi Ethan. That is correct! The only way for someone to have a negative blood type is for both parents to have at least one negative factor each.

Hi Tonia. Hi my gf is pregnant with our first child together. She has had a child before and this will be her second.

She was also not aware of what blood type she is until her recent blood tests. She discovered is A- and was subsiquently told she will have to take at least three to four shots with RhoGAM before our baby boy is born. I am now concerned having read up about potential risks mentioned herewith especially the high HDN risk when the mother is pregnant with her second baby. I am rh negative. I have 2 children whom are not the same, thankful for the rhogam injections I was given so that my babies were born healthy.

Way back in when my daughter was born, the Rhogam injection was still being understood. I received the injection within 72 hours of the birth of my daughter. Fast forward to , I had a very early miscarriage. In fact, the doctor at the ER was not completely sure if what I brought into the ER was indeed a miscarried fetus. He sent it to Pathology for determination.

While in route going home, that doctor telephoned me and left a message to call him when I got home no cell phones back then! I returned his call and he said I should come back in to the ER right away and get a Rhogam injection just in case I indeed had a miscarriage. He did not want to risk any more time if there was a delay in Pathology process in determining if it was a fetus. Although I am glad he was he was aware of this Rh negative issue, I never had any children after that possible miscarriage my choice.

Keep up the great work Carter BloodCare! Thank you for the positive feedback. We are sorry to hear about what happened to you. Thank you for sharing your story and helping others. I am A-, what does my future hold as far as child bearing is concerned? Does my blood group A- have an effect on my wife and children i hope to have in future? Hi Ronnie, Thanks for reaching out. It depends on what blood type your wife is. The risk associated with the Rh- gene only pertains to if the mother has it or not.

So, my eldest son is His father must then be 0- and I must carry a silent Rh- from my parents in order for him to be Rh-? We both carry one Rh- which would explain how he is Wondered for a long time how I could have produced My parents had 4 children. Only one is RH negative. Not all siblings have the same blood type. I had four children. I am rh d negative I v had abortion in d past without knowledge of all these so ruhgam was not given, what if i v develope d anti bodies is it possible to carry a healthy pregnancy?

Secondly, if d mother is negative and father positive who as d higher percentage of passing same blood to child? The blood that is passed to the child is determined by both parents. In regards to if your next pregnancy will be healthy, we recommend you talk with your OBGYN or primary care physician about your specific situation.

We hope that helps! My blood type is Rh- and I am been sensitized. The antibodies developed in my blood after a first pregnancy though Rhogam had been given appropriately and before a second pregnancy. The doctor suspects I had an early-term miscarriage between my two nearly full-term pregnancies. I was monitored each month during my second pregnancy, but no intervention was needed and my second daughter was born healthy and strong.

I assume she has Rh- blood. My question: Can I be a blood donor? Or, might the presence of these antibodies be potentially problematic for a recipient of my blood? Hi Sara! Thank you for wanting to donate! Our donor advocates will be able to talk with you about your specific situation and let you know if it is safe for you to donate. Please reach out to them at My first was born in the last in Is this true? I am rh- I have the rhogam shot with all my pregnancies and all my kids are fine even to my little girl who also has my blood type.

I am thankful for the articles on rh- blood it has helped me to understand more about my blood and just how much I really need to donate it which I am going to start doing and I will also encourage my daughter when she gets old enough to donate also. Thank you, Becca! It is important to learn about the blood type you have. We truly appreciate you donating and encouraging your daughter to do so as well.

We were both strong, athletic, healthy with no reason on my part to not get pregnant other than an inverted womb and his sperm count was over average. We adopted 2 beautiful children instead which is a God send, however, I wonder if it had anything to do with our blood types possibly being un compatible? Am I way off here or is this possible? Thank you! However, congratulations on your adoptions and we appreciate you doing that! What a wonderful thing. My name is Tracy and I am O-Rh-.

Since I have the o negative and rh negative I was wondering if this type is more rare? Any feedback would be appreciated. Thank you. Thank you for this article. My blood type is A- and I am Rh- as well. All 3 of my children have the same blood type. Does this mean that they may have the Rh negative trait as well.

I am a rh b negative. I had only one shot with my first child in 82 but receive 2 with my second one at 6 mons and one after delivery. No problems with either. But my sister who is O positive I believe kept having miscarriages with one certain ex husband. Could he have been rh negative??

Also can a rh B negative like my self donate blood to an O negative person whom needs blood for transfusion and also if I have had active hepatitis along with the active antibodies due to hepatitis at age 15??? Can I still donate??? Baby keeps getting jaundice…. I did however receive the anti d injection after the birth. Why does my baby keeps getting jaundice? Breast milk perhaps? Please consult a physician.

Also, would I be able to have one more baby without any complications? I was given the Rhogam shot within 48 hours of delivery. I would like to know if rhesus incompatibility affects the conception of future pregnancies. I am B negative, my husband B positive. Both of our children are RH positive. With both children I developed Hellp Syndrome severe pre-eclampsia at 37 and 36 weeks respectively. With my first child I was induced, the second was an emergency c-section.

They were born 8 years apart and since Hellp is rare, during my second pregnancy I was told the chance of getting Hellp again was slim. I had no trouble conceiving and am otherwise healthy, and my pregnancies were normal up to that point. I always felt my Rh negative status was a factor. Perhaps so. When the doctor came up to me to tell me they needed my blood I said save that babies life! We O- are humans who save lives. I thought we would be thanked by the Human Population of this world but unfortunately we are not.

YouTube videos call us fallen angel babies which are Demon babies! We are called Aliens we are said to be Dammed by God. I thank GOD that he gave me this Universal blood type because there is a 20 year old woman in this world that is alive I hope she still is that has life cause my blood runs through her veins. We appreciate your gift of life to the baby in the hospital! Anyone who donates, not just O-, are saving lives and we cannot begin to tell each and every donor how much we appreciate your gifts of life to those in need.

I am RH- and received Rhogam after 3 healthy births first being born in I and my wife has B positive blood but our first daughter is B negative while the others have B positive please enlighten me on whats going on. Do you know your blood type? Thanks for this clear information on RH Factor issues. I was told years ago I could not donate blood.

My first baby died of crib death at 4 months old. She was seemingly healthy and rh negative should not affect first pregnancy, right? I did not hear of RH negative factor till my third pregnancy.

They may have given it after second pregnancy but back then doctors did not tell u a lot. They kept me sedated three days after second birth. My second and third pregnancy produced healthy babies. Did them saying my blood could not be given to others be due to rh negative factor? Told me my blood could kill others. Kinda made me wonder how it worked in me. We are not able to give you any medical advice. My blood type is O rh-. My question is this, am I also considered O- rh-?

I had that very question. Your response: Hi Ethan. That is correct the only way for someone to have negative blood type is for both parents to have at least one negative factor each. If so, Please explain. My daughter is pregnant 10 weeks, her blood test result is O positive and RH negative, what does it mean?

Is she under risk for future 2nd baby pregnancy? What do you think? My sister was born in , her blood was not changed so she is rh-. My sister asked the doctor to humor her and give her a blood test to see what blood type she was and it was rh-. This is very confusing to me, I hope that I have explained it right. Thank you for any help that you can give me.

I want to know if this has anything with my pregnancy. Is there an honest RH- blood type registry door those in need of this blood type? I am RH- always anemic and can not donate blood.

I also have abnormal blood cells not sure what that means so I can not donate plasma either. In my first pregnancy, i was given the antigen injection only once immediately after delivery. I am pregnant with my second child now.

Please i want to know at how many weeks i need to take the antigen injection and how many times. Hello, I am O neg, and I have been carrying an Rh id card with me since I am always curious and somewhat confused about the meaning of the reference Immune Globulin and the word Human next to it in.

What does it mean, Human blood. Is my blood not human? Please clarify if you can. Thank you in advance. My daughter has an blood group of b rh positive and she is now 8yrs old.

There is no issue with being B-. All donations made through Carter BloodCare are done so freely. We do not pay for blood as we are a not for profit business. This is how I received O negative. When I was in the military, I looked for other O Neg persons in my unit and made them my battle buddy.
