Happy Blood Type Chart: Facts and Information on Blood Group Types

Post by Jaffar Saeed on Sun Nov 12, 2017 9:02 am

Blood Type (Group)
A blood type (also called a blood group) is defined as the classification of blood based on the presence or absence of inherited antigenic substances on the surface of red blood cells (RBCs). A series of related blood types constitutes a blood group system, such as the Rh or ABO system. The frequencies of the ABO and Rh blood types vary from population to population.

Main Document

Quote: "While blood types are 100% genetically inherited, the environment potentially can determine which blood types in a population will be passed on more frequently to the next generation."

When a person's blood is analyzed under a microscope distinct blood differences are visible. In the early 20th century, an Austrian scientist named Karl Landsteiner classified blood according to those differences. Landsteiner observed two distinct chemical molecules present on the surface of the red blood cells. He labeled one molecule "A" and the other molecule "B".

  • Blood Type A - If the red blood cell has only "A" molecules on it.
  • Blood Type B - If the red blood cell has only "B" molecules on it.
  • Blood Type AB - If the red blood cell has a mixture of both "A" & "B" molecules.
  • Blood Type O - If the red blood cell has neither "A" or "B" molecule.




Blood Type Facts:



There are eight different common blood types, which are determined by the presence or absence of certain antigens, which are substances that can trigger an immune response if they are foreign to the human body. Since some antigens can trigger a patient's immune system to attack the transfused blood, safe blood transfusions depend on careful blood typing and cross-matching.
There are 4 major blood groups determined by the presence or absence of two antigens (A and B) on the surface of red blood cells:

In addition to the A and B antigens, there is a third antigen called the Rh factor, which can be either present (+) or absent ( - ). In general, Rh negative blood is given to Rh-negative patients, and Rh positive blood or Rh negative blood may be given to Rh positive patients.

  • The universal red cell donor has Type O negative blood type.

  • The universal plasma donor has Type AB positive blood type.


Donating Blood by Compatible Type:

Blood types are very important when a blood transfusion is necessary. In a blood transfusion, a patient must receive a blood type compatible with his or her own blood type. If the blood types are not compatible, red blood cells will clump together, making clots that can block blood vessels and cause death.
If two different blood types are mixed together, the blood cells may begin to clump together in the blood vessels, causing a potentially fatal situation. Therefore, it is important that blood types be matched before blood transfusions take place. In an emergency, type O blood can be given because it is most likely to be accepted by all blood types. However, there is still a risk involved.

Finding Out Your Blood Type:

It is easy and inexpensive to determine a person's ABO type from a few drops of blood. A serum containing anti-A antibodies is mixed with some of the blood. Another serum with anti-B antibodies is mixed with the remaining sample. Whether or not agglutination occurs in either sample indicates the ABO type. It is a simple process of elimination of the possibilities. For instance, if an individual's blood sample is agglutinated by the anti-A antibody, but not the anti-B antibody, it means that the A antigen is present but not the B antigen. Therefore, the blood type is A.
Blood type is inherited, just like eye color. This chart shows the possible blood type of a child according to their parents blood group:

Note: In most cases, blood typing is not conclusive when attempting to determine, include or exclude an individual as the parent of a child or children.
While blood types are 100% genetically inherited, the environment potentially can determine which blood types in a population will be passed on more frequently to the next generation. It does this through natural selection. Specific ABO blood types are thought to be linked with increased or decreased susceptibility to particular diseases.

What Does Blood Group RH Factor Mean?


RH factor in blood types stands for "Rhesus Factor". Blood tests were performed on Rhesus monkeys and the Rh+ and Rh- factors were isolated. An antigen found in the red blood cells of most people: those who have Rh factor are said to be Rh positive (Rh+), while those who do not are Rh negative (Rh-). What about the meaning of RHD- Rh blood group, D antigen . The rhesus complex is not just one antigen, but several, when someone is told to be Rh+, it usually refers to the D antigen (one of the components of the Rh complex), because it's the most common, and the easiest to identify, however it's not the only one.

What is the Rarest Blood Type?


According to the American Red Cross the rarest is AB(-), present in 1% of the Caucasians, in African Americans it is even rarer. B(-) and O(-) are also very rare, each accounting for less than 5% of the world's population. Some people with rare blood types bank their own blood in advance of surgical procedures to ensure that blood is available to them.

Blood Type Diet:


The Eat Right for Your Type diet encourages people to eat certain foods and avoid others based on their blood type A, B, AB, or O. The Diet is Based on:

  • Type A ("for agrarian") - Flourishes on vegetarian diets, "the inheritance of their more settled and less warlike farmer ancestors," says D'Adamo. The type A diet contains soy proteins, grains, and organic vegetables and encourages gentle exercise.

  • Type B - The nomadic blood type B has a tolerant digestive system and can enjoy low-fat dairy, meat, and produce but, among other things, should avoid wheat, corn, and lentils, D'Adamo says. If you're type B, it's recommended you exercise moderately.

  • Type O ("for old," as in humanity's oldest blood line) - Your digestive tract retains the memory of ancient times, says D'Adamo, so your metabolism will benefit from lean meats, poultry, and fish. You're advised to restrict grains, breads, and legumes, and to enjoy vigorous exercise.

  • Type AB - Has a sensitive digestive tract and should avoid chicken, beef, and pork but enjoy seafood, tofu, dairy, and most produce. The fitness regimen for ABs is calming exercises.


NOTE: Critics cite a lack of published evidence backing D'Adamo's blood type-based diet plan.

Blood Type and Your Personality:


Legend has it that blood type tells about personality.
In Japan, it's widely believed that blood groups predict personality traits - from temperament to compatibility, to what kind of lover you are to what type of foods you should be eating. For instance:

  • Type A is calm and trustworthy;

  • Type B is creative and excitable;

  • Type AB is thoughtful and emotional;

  • Type O is a confident leader.
