What antigens are expressed if a person is blood type AB negative?

An AB- person has neither A, B or Rh antibodies in their plasma. On the red blood cell, there are A, B antigens and no Rh (or D) antigens.


how do i find a person with blood type a?

Blood types are based on having a or b antigens or neither a or b antigens in your blood. Race plays a role in blood typing, and between 16% to 40% of people have type a blood. Blood types are further broken down to positive and negative rh factors. In order to find out which blood type a person has, a simple blood test is used that will show not only the antigens but also the rh factor found in a person's blood.


How can a person have type AB blood?

they have AB blood because it has antigens


What determines a persons blood type?

A person's blood type is determined by the type of antigens of the red blood cells. there are 2 main antigens, A and B. A person with the A antigen is blood type "A." A person with the B antigen is blood type "B", a person with both antigens is "AB." And we call people without both of them type "O"


Explain blood type?

Blood types, as people commonly know, has a classification which is simply based on two things: * ABO group * Rhesus factor Now, the ABO group, depends on two antigens; antigen A and antigen B. which lie on the surface of the RBC: * A person having an A antigen on his RBC cells will show a blood type of A * A person having a B antigen on his RBC cells will show a blood type of B * A person having both A & B antigens on his RBC cells will show a blood type of AB * A person having neither of those antigens will show a blood type of O Second, the rhesus factor, which depends on a single antigen; antigen D, which also lies on the surface of the RBC: * A person having a D antigen is called an Rh positive, e.g. A, B and D antigens' presence exhibit a blood type of AB+ (universal acceptor) * A person without the D antigen is called an Rh negative, e.g. Neither A, nor B, nor D antigens' presence exhibit a blood type of O- (universal donor). Both factors combine to form the blood types as we know them today.


What is a persons blood type determined by?

If a person is blood type A then they will have red blood cell antigens of A and plasma antibodies (agglutinins) called Anti-B. If a person is Type B then they will have B antigens and Anti-A antibodies. If a person is Type AB they will have both A and B antigens, but no plasma antibodies. If a person is type O then they will have no red blood cell antigens but they will have both anti-A and anti-B plasma antibodies.


What is blood type B?

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.


Why can a person receive platelets donated by anyone?

Platelets are a small component of blood and do not have antigens. Antigens are present in whole blood and determine one's blood type.


Does Type A blood have B antigens?

No, type A blood does not have B antigens. Type A blood has A antigens.


Does a person with type O blood have A or B antigens on the red blood cell?

no


What particles in blood determine the blood group of a person?

Antigens or RH factor


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.


Which antibodies are present in the plasma of a person with type AB blood?

Since that person has anti-B antibodies, then A antigens are present in her red blood cells. Since that person doesnt have anti-A antibodies, then there are no B antigens present, which means the person has A type blood.


Does Type B blood have A antigens?

No, type B blood does not have A antigens. Type B blood has B antigens.


What is the blood type that contains antigens a and b?

Type AB blood contains both A and B antigens. This allows the person to receive blood from types A, B, O, and AB.


Does Type A blood have A antigens?

Yes, type A blood has A antigens.


What types of blood can people who are O positive accept?

People with O blood can only accept O blood. this is because type O blood does not have any antigens. Types A, B, and AB blood have A or B antigens, or both, respectively. If a person receives blood with antigens their blood does not contain it will cause their blood to clot and they will die.


Why can't you give type B blood to type A?

Different Pathogens and Antigens in the blood. Type B have B Pathogens and A Antigens. This means that if an person with blood type A receives Blood type B blood, the Pathogens will be killed and the person will probably die due to blood clotting.


What is the medical term meaning blood antigens?

Blood antigens :D


Where are the blood antigens A B Rh located?

The blood antigens A, B, and Rh are located on the membrane of the red blood cell. These antigens are hereditary.


Why can blood type O give but not receive from A type blood?

blood type O can give blood to anyone. they are the universal donor. they do not have any antigens on them so they do not react badly with any type of blood. type A blood, has type A antigens, therefore when put into a person with type O blood the blood of the person agglutinates (clumps together) and can cause serious damage to the person.


What determines whether a person is Rh positive or negative?

the antigens on their blood cells


What is a person with neither a nor b antigens in his or her blood?

you would be type O


Why a person with blood type O can't resive from a person with blood type A?

People with blood type A have so-called "antigens" on the surface of their blood cells. This is fine for them, because their immune systems have developed not to react to these antigens. People with blood type O do not have these antigens on their cells, so if A-type blood is given to them, their immune systems will attack it as a foreign invader. This causes the blood to clot inside them, which can cause damage and death.


What is the difference between ABO and Rh blood typing?

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.
