MEDICAL CORNER …. understanding different blood types!!

~~April 15, 2014~~

BY POPULAR DEMAND: A handy blood type chart for you.

Although all blood is made of the same basic elements, not all blood is alike. In fact, there are eight different common blood types, which are determined by the presence or absence of certain antigens – substances that can trigger an immune response if they are foreign to the 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 four major blood groups determined by the presence or absence of two antigens – A and B – on the surface of red blood cells:

  • Group A – has only the A antigen on red cells (and B antibody in the plasma)
  • Group B – has only the B antigen on red cells (and A antibody in the plasma)
  • Group AB – has both A and B antigens on red cells (but neither A nor B antibody in the plasma)
  • Group O – has neither A nor B antigens on red cells (but both A and B antibody are in the plasma)
There are very specific ways in which blood types must be matched for a safe transfusion: 

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.


~~Blood Types~~

In 1901, scientist Karl Landsteiner reported that blood could be classified into “types.” By matching these blood types, a successful blood transfusion could be made between a healthy donor and a patient in need of blood. Today, hospital blood banks maintain an assortment of blood products (red blood cells, plasma, platelets, etc) in a variety of blood types.

There are four main blood types: A, B, AB, and O. Each of these blood types is either RH positive (+) or Rh negative (-). So, if someone has type B blood, they have either B+ or B- blood.

The blood type of a patient determines which blood types they are able to receive as a transfusion. The blood type of a blood donor also determines who can receive their blood donation.

blood type (also called a blood group) is a classification of blood based on the presence or absence of inherited antigenic substances on the surface of red blood cells (RBCs).

These antigens may be proteinscarbohydratesglycoproteins, 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 very closely linked genes) and collectively form a blood group system.

Blood types are inherited and represent contributions from both parents. A total of 32 human blood group systems are now recognized by the International Society of Blood Transfusion (ISBT). The two most important ones are ABO and the RhD antigen; they determine someone’s blood type (A, B, AB and O, with + and – denoting RhD status).

Many pregnant women carry a fetus with a blood type different from their own, and the mother can form antibodies against fetal RBCs. Sometimes these maternal antibodies are IgG, a small immunoglobulin, which can cross the placenta and cause hemolysis of fetal RBCs, which in turn can lead to hemolytic disease of the newborn called erythroblastosis fetalis, an illness of low fetal blood counts that ranges from mild to severe. Sometimes this is lethal for the fetus; in these cases it is called hydrops fetalis.

Blood type (or blood group) is determined, in part, by the ABO blood group antigens present on red blood cells.

People with O- blood are called “universal donors” because any patient can receive O- red blood cells. Hospitals use O- red blood cells to provide emergency care for patients needing immediate transfusions. In addition, hospitals maintain a supply of O- blood for patients with an O- blood type, who can only receive O- red blood cells.

On the other end of the spectrum, very few people can receive AB+ red blood cells. However, people with AB+ blood can receive red blood cell transfusions of any blood type, and are known as “universal recipients.” AB blood is special for another reason; plasma donations from people with AB blood can be safely transfused to anyone, so AB donors are “universal plasma donors.”

There is an elemental love
by Stephen Levine

There is part of us that says
it is never too late to be reborn
on the inbreath each morning.

There is an elemental love in the universe
by which name we know each other
and encourage ourselves to live.

There is a silver river that connects everything
from which some part of us never leaves.

ocean meeting shore

There is a mercy making its way
up through the ocean of the earth
to the shores of our feet.

There is a music so sweet it is almost unbearable
that is composed between the ear
and the heart which reminds us.

There is a diamond-glint, a seed of longing
in ourselves that recognizes the potential
absence of gravity in another.

There is part of us that
says it is never too late to be reborn
on the inbreath each morning.

Somewhere there is a basket
that contains all our failures.
It is a big basket.  It wants to know
what to do with these.
Mercy has no use for them.
