Blood types, and   the need for a Blood classification system, were      first called for shortly after Blood transfusions were first     attempted around 1600 by transfusing animal Blood into humans. Blood types   are the basis of all Blood classification systems. This proved disastrous. In     the early 1800s an English obstetrician, James Blundell, came up with the idea of human     Blood used exclusively for human transfusion. Not until the 1900s were the,   no commonly accepted, basic four Blood types identified by     Karl Landsteiner. Subsequently, the success of Blood transfusion significantly increased     when patients were transfused with their same type. Now, research has shown that     transfusion with the exact type is even better. When Blood testing for Blood      type for Cord Blood banking or Cord Blood Bank and and Cord Blood Registry,      Blood type is of primary importance. Remember,   Blood test results are always best interpreted by a Blood professional or   doctor who is familiar with your Blood test history, over time.  Free Blood tests, FREE DNA testing Facts about Blood Types with charts about Blood Types and Blood type information.

One important note: in the         past, type O Blood was given to virtually anyone except those with what was termed 'rare'         Blood. Donors of Blood group O were always referred to as 'universal donors.' Today,         because of new research and a better understanding of the complex issues regarding immune         reaction related to incompatible donor Blood cells, type O Blood is no longer         automatically seen as being suitable in most every case.

In Blood banks in the United States, the most     common types of Blood cause the greatest concern. Many people with O+ and A+ do not     donate. The rationale seems to be that potential donors believe that because they are of a     common Blood type that their Blood is not needed. What they fail to think about is, YES,     they are of common type, but most Blood users are also of common type; consequently O+ and     A+ are used more than twice as much as any other donor types!

AB
People with Blood type AB negative (1/2% of the population) and AB positive are potential     universal plasma donors. This means plasma can be transfused to people having all Blood     types.
AB +
People with Blood type AB positive comprise 3-1/2% of the population. People with this     type of Blood are universal recipients. This means that they can be transfused with any     type of Blood in emergency situations. Facts      about Blood Types with charts about Blood Types and Blood type information
O +
O positive donors are needed more frequently than any other donor. Because O positive is     the most common Blood type (39% of the population), it is needed more often by people     requiring Blood in hospitals. Facts about Blood      Types with charts about Blood Types and Blood type information
O -
7% of the population has O negative Blood. People with O negative donors are potential     universal red Blood cell donors. This means that their red Blood cells can be transfused     to patients with all types of Blood. Facts      about Blood Types with charts about Blood Types and Blood type information
Simply put, your Blood is tested for ABO/Rh.     These tests identify your 'Blood type.' You may have A, B, O, or AB type Blood and may be     either Rh+ or Rh-. The basis of the Blood group tests is the ability to detect specific     substances, or antigens, on the red Blood cells. The A antigen is on type A cells; the B     antigen is on type B cells. If neither A nor B antigens are detected, the donor has type O     Blood; if both are present, the donor has type AB Blood. If the major Rh antigen is     present, the donor is Rh+ (for example, O+, A+, B+, or AB+); if not, the donor is Rh- (O-,     A-, B-, or AB-).
There are more than 600 other antigens that     have now been identified on red Blood cells. These sub-types are important, but often not     considered.
In Short, What are Blood Types?
Everybody has a Blood type. The most common Blood type classification      system is the ABO system discovered and defined by Karl Landsteiner in the      early 1900s. There are four types of Blood in the ABO system: A, B, AB, and      O. Your Blood type is established before you are born, by specific genes     inherited from your parents. You receive one gene from your mother and one      gene from your father; these two combine to establish your Blood type. These two      inherited genes determine your Blood type by making proteins called agglutinogens exist on the surface of      each red Blood cell in your body. Blood test      results are important in Blood disorders in Blood test and Blood tests with      Rare Blood types.
There are three alleles (variations) of the Blood type gene: A, B, and O. Since      we all have two copies      of these genes in our Blood, there are six possible combinations; AA, BB, OO, AB, AO, and      BO. These combinations are referred to as genotypes, and they      describe the genes you got from your parents.
In addition to the proteins existing on your red Blood      cells, other genes make proteins called agglutinins that circulate in your      Blood plasma. Agglutinins are protectors of our bodies and are responsible for ensuring that only the Blood      cells of  our own particular Blood type exist in  our bodies.
Physicians rely on "Blood-work," or clinical laboratory      diagnostic Blood testing to diagnose medical conditions. From this Blood      testing the medical professional then prescribes therapies and remedies,      based on those Blood tests. Good Blood tests make possible state-of-the-art      lab procedures that can be provided directly to the public in private and      these Blood tests can be provided affordably.
