Know Your Blood Group with Blood Type Chart.
The most important purpose to know your blood group is for the times of medical adversity. At the time of an emergency like lack of basic health components in the body like hemoglobin or at an event of an accident where in an external supply of the blood (transfusion) is essential, the knowledge of your blood group becomes vital. Hence it is essential and extremely crucial to get a blood test done.
What are Blood Group or Blood Types
A blood type (also called a blood group) is a classification of blood based on the presence and absence of antibodies and based on the presence or absence of inherited antigenic substances on the surface of red blood cells (RBCs). These antigens may be proteins, carbohydrates, glycoproteins, or glycolipids, depending on the blood group system. Some of these antigens are also present on the surface of other types of cells of various tissues. Several of these red blood cell surface antigens can stem from one allele (or an alternative version of a gene) and collectively form a blood group system.
ABO types -
ABO types were the first of the discoveries.
- Group A – Antigen A with antibody B
- Group B – Antigen B with antibody A
- Group AB – Antigen AB has no antibodies
- Group O – Antigen nil (group O) with antibody A and B.
Rh types -
There are 5 main Rhesus (Rh) antigens on red cells – C, c, D, E, e.
The most important of these is the Rh D group. The positive (+) or the negative (-) after the letter A, B, AB or O is given by the D antigen on the red cell. In general practice, 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 blood type.
It is essential to know the blood matches as that decides the availability of blood and the readiness of transfusion from one body to the other.
- Group O can donate red cells to anybody. It’s the universal donor O
- Group A can donate red cells to A’s and B’s
- Group B can donate red blood cells to B’s and AB’s
- Group AB can give blood only to other AB’s but can receive from all others
Blood Type Determination
It is inherited. Like eye color, blood type is passed genetically from your parents. Whether your blood group is type A, B, AB or O is based on the blood types of your mother and father.
This chart shows the possible blood types you may inherit.
