Mother Baby Blood Type Mismatch (Definition)

Mother Baby Blood Type Mismatch, also known as ABO incompatibility, occurs when a pregnant mother has a different blood type than the developing baby. Exposure to the baby’s blood type, either from that pregnancy or a previous sibling, causes the mothers body to develop antibodies to the blood type. The condition is dangerous as antibodies can cross the placenta and cause anemia (blood cell destruction), jaundice, or fetal ...Read more

What is the meaning of Rh 'd' positive?

What is the meaning of Rh 'd' positive?

Rh D positive: Rh is a blood grouping system like ABO system. Rh is taken from rhesus monkey. There are specific proteins called antigens on rbcs. They are termed a, b, c, d, e and so on. There are many of them. It means that antigen d is present on the rbcs surface. The rh system is important in hemolytic anemia of newly born babies. Thanks. ...Read more

What is the different between the blood group "a Rh 'd' positive" and "o Rh 'd' positive"?

What is the different between the blood group "a Rh 'd' positive" and "o Rh 'd' positive"?

Group A and O: The different is one has blood group o+ - and the other has blood group a+. Group o has no antigen a and b, but has antibody to a and b. So, group o is a universal donor- and the blood can be given to people with different blood group. Group a has antigen a, and antibody b. So, can receive group a or o blood. Group o only can receive blood group o if needed any blood transfusion. ...Read more

Rh negative and not sure who the baby's father is. Odd are Rh positive like 85% of the population, right?

Rh negative and not sure who the baby's father is. Odd are Rh positive like 85% of the population, right?

Correct: Because you are rh negative, you should be offered Rhogam at 28 weeks and after delivery if the baby is rh positive. Also, there are some other situations where Rhogam may be given, but they are less common. ...Read more

What is expected when a man of a+ and woman of o rh+ produces an offspring ? Could this translate to any complications in terms of blincompatibilit

What is expected when a man of a+ and woman  of  o rh+ produces an offspring ?  Could this translate to any complications in terms of blincompatibilit

ABO: You are a+, the woman is o+. Women who are o+ carry anti-a and anti-b antibodies. The child will either be a+ or o+. If the child is a+, there is a chance that mother's anti-a antibodies will be high and cross the placenta and cause red cell break down. This doesn't affect the baby in utero but may cause high bilirubin levels (or jaundice) in the new born. ...Read more

Why rhd incompatibility of the mother and fetus doesn't affect the present fetus but subsequent pregnancies?

Why rhd incompatibility of the mother and fetus doesn't affect the present fetus but subsequent pregnancies?

See below: The incompatibility occurs when the mother is exposed to the blood of the new baby. This usually occurs at delivery. The mother then makes antibodies to that "foreign substance" and this can adversely affect the next pregnancy as the mother's immune system will see it as a "foreign" body and want to get rid of it. This problem is usually treatable with an injection at the birth of the first child. ...Read more

What is the health implication and risk of sc blood genotype woman?

What is the health implication and risk of sc blood genotype woman?

Clarification: Are you asking what is the implication of having the sickle cell? A woman can have one gene for sickle cell and this makes her a carrier. Typically carriers who are heterozygous for the disease are asymptomatic. Or, she can have 2 genes (one from each of her parents) of the sickle cell gene and that typically will make her have sickle cell disease. I'm not sure if that answers your question? ...Read more

Why the Rh is imporyant?

Why the Rh is imporyant?

Unborn child: Some people have the common rh sensitizing antigen on their red cells and some don't; it's inherited. If dad has this and mom does not, mom can make antibodies against it (especially after the first such baby); these can cross the placenta and destroy the child's red cells, causing severe illness or death -- once very common. Rhogam at delivery usually prevents mom from getting sensitized. ...Read more

What is the role of placenta in pregnancy?

Many: It's primary function is to act as a go between with your system and the baby's. It can filter out bad stuff and let good stuff (nutrients) in. It allows for the proper transfer of everything from calories to antibodies to the baby. A healthy and normally functioning placenta is critical to the baby's health. ...Read more

What is the function of the extra domain in IgE & igm?

What is the function of the extra domain in IgE & igm?

Trick question: Are you studying immunology? The extra domain on ige indicates a unique role for the c2 domain in the interaction between ige and fcri. C2 reduces the off-rate of the ige/fcri, thereby resulting in a more stable complex. It is felt that the domain on igm co-contributes to the pentamic structure production. ...Read more

Also does the Rh factor affect a baby's vulnerability to the disease?

Also does the Rh factor affect a baby's vulnerability to the disease?

Generally no: A negative Rh factor does not make a baby more susceptible to disease in their lifetime, either thru infection, environmental factors or bad habits. In the rare instance where they might need a blood transfusion, they could only get it from Rh negative donors.Females would require more monitoring during pregnancy if their spouse was Rh+.It is generally of no longterm consequence. ...Read more

What is the importance of having a negative blood group?

What is the importance of having a negative blood group?

Transfusions: The major importance of being Rh negative (Rh-) is that you could have a severe, potentially life-threatening or even fatal reaction if you received blood from an Rh positive (Rh+) individual. Rh+ ppl can receive Rh+ or Rh- blood, while Rh- ppl should receive only Rh- blood. The other consequence is in pregnancy. I've run out of space, but Rh- mom and Rh+ baby can lead to problems in future preg ...Read more
