The Rh factor refers to the presence or absence of a specific protein on the surface of red blood cells, while A, B, and O antigens refer to different types of carbohydrates found on the cell membrane. The Rh factor is a separate antigen system from the ABO system and does not directly influence blood typing based on A, B, and O antigens.

Where are the blood antigens A B Rh located?
Blood antigens A and B are located on the surface of red blood cells, while the Rh antigen (Rh factor) is also found on the surface of red blood cells. These antigens determine an individual's blood type.
How many types of antigens on the erythrocytes?
There are two main types of antigens on erythrocytes - ABO antigens and Rh antigens. ABO antigens include A and B antigens while Rh antigens include RhD antigen. These antigens play a crucial role in determining blood type compatibility for blood transfusions.
Where does the positive and negative for blood come from?
The positive and negative blood types come from the presence or absence of certain antigens on the surface of red blood cells. Blood type A has A antigens, B has B antigens, AB has both A and B antigens, and O has neither A nor B antigens. The positive or negative designation refers to the presence or absence of the Rh factor antigen.
What antigens are expressed if a person is blood type AB negative?
If a person is blood type AB negative, they express antigens A and B on their red blood cells and lack the Rh factor antigen. This blood type is considered rare.
What is the difference between blood types?
The red blood cells define the blood group you actually belong to. There are small markers known as antigens on the red cells surface, but they are so tiny that it cannot be viewed under a microscope. However, every person has different antigens but for identical twins. The antigens identify the blood types and are the key to match the transfusions as well that helps in avoiding serious complications. The blood group structure is defined as the ABO system. Another significant factor worth considering is the Rh system. All the blood groups have the possibility of having Rh antigens. Conversely, there are some who have it, while some do not have it. In case, the blood group belongs to Rh antigens, then they are Rh positive and a person having A blood group with Rh positive is recognized as A+. In case a person has A blood group with Rh negative, then it is A-. This is the same pattern followed for O, B or AB blood group as well. The Rh system duals the blood groups effectively so that the positive blood type does not get mixed with negative.
Where are the blood antigens A B Rh located?
Blood antigens A and B are located on the surface of red blood cells, while the Rh antigen (Rh factor) is also found on the surface of red blood cells. These antigens determine an individual's blood type.

The positive and negative blood types come from the presence or absence of certain antigens on the surface of red blood cells. Blood type A has A antigens, B has B antigens, AB has both A and B antigens, and O has neither A nor B antigens. The positive or negative designation refers to the presence or absence of the Rh factor antigen.
Which antibody and antigen combination match each blood type?
The blood type notation A Rh- indicates which antigens and antibodies are present in the blood. A indicates there are A antigens. Rh+ indicates there are Rh antigens. B antibodies. If there are A and Rh antigens but no B antigens, the antibodies in the blood plasma are B antibodies.
What antigens are expressed if a person is blood type AB negative?
If a person is blood type AB negative, they express antigens A and B on their red blood cells and lack the Rh factor antigen. This blood type is considered rare.
Substance that determines blood types is found in the membrane of red blood cells?
Antigens. Your blood type depends if you have A, B, AB, or none of those antigens (O). These antigens can also be positive or negative depending on whether you have the Rh antigen, or Rh factor.
Does o- blood effect pregnancies?
Each person's blood is one of four major types: A, B, AB, or O. Blood types are determined by the types of antigens on the blood cells. Antigens are proteins on the surface of blood cells that can cause a response from the immune system. The Rh factor is a type of protein on the surface of red blood cells. Most people who have the Rh factor are Rh-positive. Those who do not have the Rh factor are Rh-negative
Describe the antibody antigen interactions that would occur if an Rh- perosn with type B blood received blood from an Rh person with type AB blood?
The Rh- person has no Rh antigens, so their body does not recognize the Rh antigens on the Rh+ donor blood as foreign. However, the B antigens on the donor blood are recognized by the recipient's immune system as foreign, leading to an immune response against the B antigens. This can result in a transfusion reaction if not properly managed.
Which blood types in terms of the ABA and Rh antigens can be donated to somebody with type AB blood?
B+ here is a guide for you: type A - A antigens B antibodies; type B - B antigens A antibodies; Type AB - A&B antigens and no antibodies; type O - no antigens and A&B antibodies. for the rh you just have to add if it is + or -.
Why is testing for Rh antigens and antibodies different from ABO testing?
Testing for Rh antigens and antibodies is done to determine the presence of the Rh factor in the blood, which is a separate system from the ABO blood group system. Rh testing is important for determining compatibility in blood transfusions and during pregnancy. ABO testing, on the other hand, evaluates the presence of A, B, AB, or O antigens on red blood cells to determine blood type.
What is type B blood?
Human blood contains antigens. Antigens can make one person allergic to the blood from another person. There are two main antigens, A and B. A person without either has type O blood. So a person can have type A blood, type B, or type O. Also a person can have a combination of A and B antigens and have type AB blood. In addition blood has an Rh factor, which can be positive or negative. So a person can be A positive or A negative, O positive or O negative, and so forth. B+ simply means a person has type B blood and is Rh positive.
What is b plus blood type?
Human blood contains antigens. Antigens can make one person allergic to the blood from another person. There are two main antigens, A and B. A person without either has type O blood. So a person can have type A blood, type B, or type O. Also a person can have a combination of A and B antigens and have type AB blood. In addition blood has an Rh factor, which can be positive or negative. So a person can be A positive or A negative, O positive or O negative, and so forth. B+ simply means a person has type B blood and is Rh positive.
