Rh blood system

Common Questions and Answers about Rh blood system


Avatar f tn People who are Rh- do not carry the D antigen on their red blood cells. A mother who is Rh- could have a Rh+ baby. An Rh- mother's immune system can see the Rh+ red blood cells from the baby as foreign and will develop antibodies against them. These antibodies can then pass from mother to child and attack the babies Rh+ red blood cells. This can cause anemia, jaundice, and even heart failure in the baby. Rh- mothers are given the rhogam shot during their 28th week of pregnancy.

It's like an immunization. It introduces a small bit of RH+ into your system so that your body won't attack it. If this baby you have is RH+ and it's blood were to get in contact with your blood your body could attack your next baby if it is RH+ causing a miscarriage.
849762 tn?1288188348 In first pregnancies, Rh sensitization is rarely a problem because the mother’s blood and the baby’s blood typically do not interact directly until delivery -- but if Rh-positive blood (such as from the baby) enters the Rh-negative mother’s blood, her immune system may develop antibodies against Rh factor. If these antibodies then enter an Rh-positive baby’s bloodstream, the antibodies can begin to attack the baby’s blood, causing jaundice or more severe symptoms if left untreated.

Avatar n tn I was not given Rhogam again as it was still in my system determined by blood test. I was bleeding brown blood for the past 3 wks and asked my my ob if I should have Rhogam again. Bloodwork was taken along with a test called the Kleihauer-Betke test. This test showed that I had fetal blood cells in my system. I am worried that the Rhogam I got in wk 4 may not have been strong enough. I read if an ounce of fetal blood mixes in with yours you would need two shots of Rhogam.
Avatar n tn , the term "Rh" refers to a particular protein, the Rh factor, that sits on the surface of red blood cells (the surfaces of all cells are dotted with some protein or another). About 85 percent of the population carries the Rh-factor protein on their cells. That makes them Rh-positive. Some folks, such as you, don’t have the protein and are Rh-negative.     Does it make any difference in your daily life? Not in the slightest.
Avatar n tn or if you've had a blood tranfusion or received blood products of some kind there's a risk you could become Rh-sensitized or isoimmunized. Isoimm. means you make antibodies that circulate inside your system which don't harm you but can attack the Rh-pos. blood of your growing baby. (IF your baby is Rh-neg, theres no problem.) Your antibodies can cross the placenta & attack your babys blood. This can cause blood disease of the fetus or newborn.
Avatar n tn During pregnancy and at birth some of the baby's blood cells can enter the mother's blood stream . If the mother is RH- and the baby is RH + , the baby's cells entering the mother's blood stream are sensed as a foreign material and her body's naturally occurring defense mechanism will start to produce antibodies to destroy this foreign material. Once these antibodies are developed they remain in the blood stream for life.
Avatar f tn they also said that that if it was a bad labour and and the babys blood got into ur system it starts building up antibodies and can be harmful to the next baby because it see its as something foreign in ur body.
Avatar f tn And it is to protect your baby from the antibodies in your blood. When your blood is RH negative your body will try to kill the baby as a foreign substance in your body and try to expel it. For some reason that is what happens. It's like your body cannot recognize that it is a baby and is safe. So it is just your body's defenses kicking in. But as blueeyedtabbycat said you'll get the shot soon. Not sure where they stick you. Probably the bicep.
Avatar f tn It stops your bodies antibodies from attacking the baby when it realizes that blood shouldn't be in your system. And the shot after the baby is to restart them so to say. I had this problem with my first and he is perfectly okay. Im going to get the shot myself in 10 weeks.
Avatar f tn And your blood type alone has nothing to do with 'killing the baby'. It is if your blood crosses PATHS with the baby's blood and you have antibodies in your system, your blood see's it (baby's blood) as a threat - and will kill off the healthy cells like an infection - in turn, causing you to miscarry. This only can happen IF you bleed during pregnancy. I had my first pregnancy to term, and had a rhogam shot at 28wks, and after birth.
Avatar f tn It's basically a shot you get to keep you from being allergic to your baby. Neg blood types can only give blood to neg blood types. If your baby is a pos blood type then your own body would see your baby as a foreign body and try to attack it making both of you sick and causing you to possibly miscarry. The shot keeps that from happening. Best way I know to explain it.
849762 tn?1288188348 anyone have rh- blood and not get the 28 week shot and had no problems with pregnancy? I'm researchng lots about it but would like to hear personal expriences.?
1047234 tn?1253547296 I have Fibromyalgia and am RH negative, as well!
Avatar f tn I had to delve into this some myself, RH factors are ion channels on red blood cells. Mycoplasmas and Lyme, among other micro-vermin, like to live in RBCs. It would therefore make sense that they would be able to "turn off" an ion channel for something that made them less comfy in their new homes. How insidious! God I hate parasites!
Avatar f tn If a women is rh neg then there is a chance that your blood can contaminate the baby's blood. Im rh neg. I had to get one when I had a both miscarriages. With my 1st I got one at 28 weeks and after I delivered him. My son is postive like my husband. I had bleeding early on in this pregnancy so I got the rogan shot then. I will get it again at 28 weeks and then when I deliver.
Avatar n tn If your baby's blood mixes with yours for any reason your immune system is going to want to build antibodies against the Rh+ blood since it is foreign. If you become pregnancy again with another Rh+ baby your immune system will try to destroy it. Rhogam prevents that from happening. You should get a Rhogam for this pregnancy if you have had an amneo or a accident that may have cause trauma to the abdominal area or any time when the Rh+ blood could possibly mix with yours. Hope that helps.
Avatar n tn You'll need a shot after the birth if your newborn is found to be Rh-positive, because if you were exposed to Rh-positive blood during delivery, the shot will prevent your body from making antibodies that could attack an Rh-positive baby's blood during a future pregnancy.The shot (Rh immunoglobulin) is given to you during the pregnancy and then again after you deliver or m/c. This is only an issue for mom's that are RH- factor like I.
Avatar f tn It's sort of a toss up depending on how much antibody gets into the baby's blood system if they have Rh. I do know that another way a first time Mom that is Rh negative can get exposed to Rh and get sensitized is miscarriage, but I'm not sure at what stage they consider the possibility of the blood comingling causing a problem. I did read that 2% of women that are past 30 days gestation can get sensitized to Rh if the baby was Rh positive.
Avatar n tn Does Rh-neg blood type have a low risk for cancer, but a high risk for diabetes, heart disease & autoimmune problems? A large number of family members on my mother's side (about 10 so far) who are Rh-negative blood type have died or having major problems with diabetes, heart disease and autoimmune system. The other side of my family are Rh positive and they are being stricken with various types of cancer (about 8 so far), but they do not have the other health problems.
1011504 tn?1250813116 A month later i got preg with this one i am due to have next week and once this baby is born they will test its blood to see if s/he is Rh positive and if so i'll have the shot again. I was told with all the pregnancies that if i had any bleeding i needed to go have the shot but i've never needed to. So i hope this helps a bit and clears up a few questions you might have. Good luck and hope you are still pregnant.
Avatar n tn Another medically important blood type is described in the Rh system. These genes were first discovered in the rhesus monkey, hence the designation Rh. The Rh system is actually far more complex than the ABO system in that there are 35 different possibilities that one could inherit from each parent. These, however, are roughly grouped into positive and negative types. In this system the positive are dominant over the negative.
Avatar m tn do you mean the Rh factor, which typically expresses itself as Rh+ or Rh-? I forget exactly what the Rh stands for, but it is something else found on the blood. (Most cells in a human body have thousands of different signals and signs to identify them.) For instance I would say that I am A+, my husband is O+, and my ex flatmate AB-. That positive or negative sign is actually another genetic trait independent of the ABO and is the second way that blood is usually classified.
Avatar f tn My sister in law was told that this could have been the reason she miscarried one of her babies and it caused some major health problems for one of my nieces. Because the baby was Rh-, her immune system was fighting off the maternal blood which lead to a severe case of anemia. She's fine now, but it initially caused a lot of problems. On the reverse if a mother is negative Rh and has a baby with +/-, she herself could die.
Avatar f tn You only get it if you have a Rh negative blood type (eg AB negative) you get one at around 28 weeks and the other after labour.
458509 tn?1208398002 If the baby's Rh positive blood enters a mother who is Rh Negative, then her immune system sees the cells as 'incompatible' or 'foreign' and will subsequently produce anti-rhesus antibodies to try to destroy them for her own self-protection. This may not seem like a big problem, however, if she has another pregnancy where the baby is Rh positive, then these antibodies that have formed will pass into the baby's bloodstream via the placenta and attack the red blood cells of the baby.
Avatar f tn I have O- blood and I have just found out that I am expecting. My mum suffered various miscarriages due to this reason as her body rejected the baby. I'm scared incase I do the same as it's just nature. What can I do to prevent this? Someone please help.
Avatar n tn They don't take your white blood cells, so your immune system will not be harmed (unless you don't drink enough water). I have been donating for almost a month and I do have a cold right now, but a lot of people on the bus looked sick, so I can't blame donations. I actually started exercising about 3 weeks ago and have put on a good amount of muscle already. I can't stress this more. Eat 1 extra meal per donation and drink plenty of water (or Gatoraide).
Avatar f tn O is a universal donor I believe. Sometimes when the baby has a different blood type than you your immune system will attack it.
