Human blood group systems In the ABO system, (and Rhesus D system) all blood belongs to one of four major groups: A+/−, B+/−, AB+/−, or O+/−. The presence (+) or absence (−) of the RhD (Rhesus D) antigen is indicated by the plus or minus following the ABO type. But there are more than two hundred minor blood groups that can complicate blood transfusions. These are known as rare blood types.

Why Canât You Use Blood from Someone Who Has a Different Blood Type Than You? First, a breakdown of the four blood types: 1  Type A: Only the A antigen on red cells (B antibody in the plasma). The second most common blood type. 2  Type B: Only the B antigen on red cells (and A antibody in the plasma). Relatively rare, especially among Hispanics and Caucasians.

How many different blood types are there? In brief: Many. A+, a-, b+, b-, ab+, ab-, o+, o-. If you are getting a blood transfusion, there are many other factors to take into consideration. Kell, lewis, and other factors have to be matched so that there won't be a reaction. Without a perfect match, you may have a big problem in a transfusion situation. In brief: Many.

Blood Types Donate Blood - The Blood Connection. Blood Types. Human blood is divided into one of four main blood types (A, B, AB, and O) and are based on the presence or absence of specific antigens on red blood cells. Blood types are inherited and consist of red blood cells, white blood cells, platelets and plasma.

Blood Type Chart: Facts and Information on Blood Group Types One of the rarest blood types in the world is Rh-null, which lack any antigens in the Rh system. There are only 9 active donors in the community of rare blood donors that have Rh-null blood. Rh-null is considered a “universal blood” for anyone with a rare blood type within the Rh system.

Why do people have different blood types? The types of proteins, glycoproteins and glycolipids found (or expressed) on the surface of red blood cells define blood types. In addition, blood types, or at least the genes responsible for them, are inherited. Karl Landsteiner described the original blood types--A, B and O--in 1900 and doctors now recognize 23 blood group systems with hundreds of different types.. Many of the blood type antigens (and the antibodies that react with them) have been discovered as a result of transfusion incompatibilities.

- We get 8 in total because of the Rh- Factor and the blood types it produces including A-, B-, AB- and O-. Approximately 85% of the US Population have the Rh+ Blood Types of A, B, AB or O. Thus, resulting in a very small population of the more rare Rh Negative Blood Types. For many years Type O+ Blood was incorrectly considered to be the Universal Blood Donor.

Blood Human blood. The ABO blood group system was discovered in the year 1900 by Karl Landsteiner. Jan Janský is credited with the first classification of blood into the four types (A, B, AB, and O) in 1907, which remains in use today. In 1907 the first blood transfusion was performed that used the ABO system to predict compatibility.

How to Study Haematology AB0 blood grouping system. According to the AB0 blood group system there are four different kinds of blood groups: A, B, AB or 0 (null). Blood group A. If you belong to the blood group A, you have A antigens on the surface of your red blood cells and B antibodies in your blood plasma.

The Mystery of the Vel-Negative Blood Type The ABO blood group isn't the only one. In fact, there are about 34 different human blood groups. Now, scientists in Nature Genetics have explained the genetic basis behind a rare blood group called Vel. Vel Blood Group Most people are Vel+ (Vel-positive), meaning that they possess the Vel antigen on the surface of their red blood cells. However, about 1 in 5,000 individuals are Vel- (Vel-negative), and thus do not carry the antigen. Their immune system recognizes the Vel antigen as foreign, and if given Vel+ blood, they can experience kidney failure or possibly death. A screen currently exists for this blood type, but it can be inaccurate; therefore, identifying the blood type's genetic basis will allow doctors to more easily screen patients.

Facts About the Most Uncommon Blood Types You Probably Didn't Know This article will give you more information on rare blood types. Advertisement. We know that A, B, AB and O are the four blood groups that can be Rh positive or negative (viz: A+, A-, B+, B-, AB+, AB-, O+ and O-). Among them, O+ is the most common; while AB-is the rarest blood type. The detailed explanation provided here will help in better understanding of the subject.

What are Some Rare Blood Types? Within the ABO/Rhesus Group systems which are used to classify most blood types, there are several rare blood types. The rarest is AB-, with less than one percent of the world's population having this blood type.B-and O-are also very rare, each accounting for less than 5% of the world's population.ome of the other antigens used in blood typing include: D Factor, C Factor, E Factor, M Factor, S Factor, Le(a) Factor, K Factor, Fy(a) Factor, Jk(b) Factor, and Fy(b) Factor, among others. This means that someone could have a blood type such as AB-: Fy(b)-, K-.

Which Blood Type Is the Universal Acceptor? Blood type is categorized based on which antigens are on the red blood cells. There are four antigens, or antigen groups: A, B, AB and O. Each of these can further be divided into positive and negative. For example, a person can have either A- blood or A+ blood.

How Many Blood Types Are There The most well-known and medically important blood types are in the ABO group. They were discovered in 1900 and 1901 at the University of Vienna by Karl Landsteiner in the process of trying to learn why blood transfusions sometimes cause death and at other times save a patient.ll humans and many other primates can be typed for the ABO blood group. There are four principal types: A, B, AB, and O. There are two antigens and two antibodies that are mostly responsible for the ABO types.
