Blood TYPES – everyone has one

A simple primer for blood types…
Why blood types are deadly serious

There are 4 BASIC TYPES of blood. When you count
‘positive’ and ‘negative’ – there are eight categories.

They are called: A(+ or -) – B(+ or -) – AB(+ or -) – O(+ or -)

Here’s how the classifications are determined.

There are two distinct chemical modules present on the
surface of red blood cells. On molecule is referred to as
“Molecule A” – the other “Molecule B”.

If the red blood cell had only "A" molecules on it, that blood is called Type A.

If the red blood cell had only "B" molecules on it, that blood is called Type B.

If the red blood cell had a mixture of both molecules, that blood is called Type AB.

If the red blood cell had neither the “A Molecule” nor the “B Molecule”, that blood is called Type O.

The Potential Big Problem with Blood Types:

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.

That’s why it’s 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 (no guarantees) to be accepted by all blood types – but there is still a serious risk involved.
