Which blood group can have a parent? To find out this, you need to know the child's blood group and the other parent. Online computers and tables provide us with only a gross estimate, a blood test confirms the group safely.
There are several criteria that influence the Blood Group . It is about the properties of the red blood cells in the blood as well as sugar and proteins on their cell membrane. The red blood cells provide information about their type and thus also their blood group on their surface. Important information is also shared by the plasma leaf, especially about the presence of antibodies.
About 50 blood group systems are known, which include different types of blood group. However, the Ab0 and rhesus factor systems are most important for the description of humans. The RH factor was named after the macaca mulatta macaca or also called rhesus monkeys. Exactly with these monkeys he was discovered for the first time. The discovery was attributed to the scientist Karl Landsteiner in 1901. As part of the AB0 system, we differentiate the blood groups A, B, from and 0.
blood group of parents and child
The parents influence their child's blood group. A gene of the blood group is inherited by the mother and a gene. You cannot consciously influence it, you do it in a genetic way.
If a parent has blood group A and the other blood group B has, your offspring can get one or both genes for groups A or B, causing him to become a blood group. If both parents only have genes for group 0, their offspring will also have group 0.
In the table we see possible hereditary combinations of the blood group:
the gene for rh
The gene for the RH factor is available on the blood cells or not. It is the most important antigen D, otherwise there are also VAC antigens. If a person has this gene, they are called RH-positive. Otherwise, that is, if she doesn't have it, we speak of RH-negative. If one parent is RH-positive and the other RH-negative, their descendants can have one of the two groups.
The child's blood group depends on the combination of the genes that it inherited from the parents. Therefore, it is also possible that the child has a different blood group than his parents.
In the case of RH antigens, problems can arise during pregnancy. This happens because the blood of the fetus carries half of the mother's genes, but also from the father. Half of the father is alien to the mother's body. Usually there is no mixing of the blood of the mother and the fetus, but there are exceptions. Sometimes a small amount of the blood of the fetus gets into the cycle of a Rh-negative mother. Then an antibody reaction forms. In such cases, the mother is administered anti-D immunoglobulin that prevents an immunological reaction from the mother.
What is rh-sensitization?
The mother's immune response is a process in which the mother's immune system reacts to antigens (foreign proteins) in the body of her fetus as a foreign object and tries to neutralize it. This reaction occurs because the fetus has other antigens from the father who are foreign to the mother and can be considered a threat to her immune system.
One of the best-known forms of the mother's immune response is the so-called RH sensitization. In this case, a RH-negative mother who is pregnant with a RH-positive fetus can be exposed to antigens of the fetus. This is mainly done during birth, but it can also occur during other situations if the blood circulation of the mother and the fetus come into contact. When this happens, the mother's immune system begins to produce antibodies against the RH factor that is found on the blood cells of the fetus. In the next pregnancy, these immune response can cause complications including hemolytic disease of the newborn.
Therefore, preventive measures are recommended in cases of rh-sensitization and similar situations. The goal is to minimize the risk of an immune response from the mother to the fetus. These measures can include the administration of immunoglobulin, i.e. antibodies against the RH factor to the mother. This happens in the situations mentioned, i.e. after birth or after other risky situations that could lead to a mixture of the blood of the mother and the fetus.
What is the newborn hemolysis syndrome?
The newborn hemolysis syndrome (NHS) is also known as fetal erythroblastosis or rh-sensitization. It is a state that appears in newborns that have a different blood group than her mother. This occurs in mothers with a negative blood group, usually group 0, that produce antibodies against the blood cells of the fetus with a positive blood group. These can penetrate the placenta and damage the red blood cells of the fetus. This is most common in the cases mentioned when the mother is RH-negative and the father RH-positive.
If this disease is not recognized in time and not treated in time, it can lead to serious health problems in newborns. The complications include, for example, anemia, jaundice, brain damage, seizures or even death.
How is it going on in the case of HCN? The treatment includes the blood transfusion of the newborn, blood exchange or phototherapy. The latter helps to eliminate excess bilirubin in the child's body. HCN can be avoided early and safely.
It is absolutely necessary to carry out a blood test during pregnancy. This identifies risk factors, such as the different blood group of mother and fetus mentioned by us. In such a case, preventive measures should be taken. These measures include the administration of antibodies against the RH factor to the mother during pregnancy and after birth to minimize the risk of HCN.
What is a blood group?
A blood group is a genetically determined property of blood cells based on the presence or absence of certain molecules on the surface of blood cells. These molecules are called antigens and can be present on the surface of erythrocytes (red blood cells), leukocytes (white blood cells) and plates
There are several classification systems for blood groups, but the most common are the AB0 and RH systems. In the AB0 system, blood groups based on the presence of A and B antigens are divided into the surface of erythrocytes into A, B, from and 0. Blood groups in the RH system are then referred to as RH-positive or RH-negative.
Why are blood groups important?
blood groups are important for several reasons. They are important for some diseases or during pregnancy. It is about being able to influence the compatibility between mother and fetus or between donor blood and recipient.
You are also important in the (link away), especially when examining the influence of blood groups on the risk of different diseases such as cardiovascular diseases, cancer or infections.
You also help to determine biological relatives. Blood and blood groups in particular are used to determine the biological relationship between people.
blood transfusions are of great importance for life -saving measures. People with different blood groups can have different antigens on the surface of their blood cells. It is precisely this antigen that can trigger an immune reaction if you get into the body of a person with another blood group.
blood donation
worldwide there are around 119.54 million blood donors. It is a process in which one person voluntarily donates their blood. A (left) is essential for patients who need blood during operations, treatment for serious illnesses or after accidents. The blood donated is then used to save the life of other patients.
The blood donation process usually begins with the registration of a voluntary blood donor that must meet certain health and retirement requirements. This is followed by a short medical examination of the taken blood sample, and it is also determined whether the candidate for donors meets the requirements for donating blood. The examination can include blood pressure measurements, weight, blood count and tests on infectious diseases such as HIV or hepatitis.
The blood donation itself takes about 10-15 minutes. During this process, the doctor introduces a needle into an arm vein of the donor and the blood is collected in a sealed bag. After the blood donation, the donors usually receive drinks and snacks so that they can recover from blood sampling.
What is blood and what function does it have in the body?
blood is the most valuable liquid in our body. It circulates in the body and serves as a transport system for oxygen, nutrients, hormones, blood cells and waste products. All blood components are formed in the bone marrow. Blood cells and blood plasma are created here. Used or old blood cells are captured, so to speak, and broken down by the spleen. The fact that it is also called the cemetery of the blood cells must have already been learned in primary school.
blood consists of the two main components already mentioned - blood cells and blood plasma. Blood cells include red blood cells - erythrocytes, white blood cells - leukocytes and platelets - platelet. Blood cells have different functions, such as the transport of oxygen, combating infections and blood clotting. Blood plasma is part of the yellow colored blood. It makes up about 55 percent of the blood volume. It contains water, proteins, sugar, minerals, hormones and waste products. Blood plasma helps to maintain the balance between the different blood components and ensures the transport of nutrients and waste products and from different parts of the body.
blood plays an important role in our body and its composition and properties can be influenced by various factors such as age, nutrition, movement, illness and treatment.
