What is A+ blood compared to A- ?

Question

Hello,

I asked my primary care doctor for blood my blood type. He told me I am: A+. What is A+ compared to A- in most simplest none doctor form. How does it differ and which is better? Additionally how does it compare to other three groups ? I know O is the best needed as it is rare.

Answer 1

The - or + refers to the Rhesus Factor. The Rhesus factor, also known as the Rh factor, gets its name from experiments conducted in 1937 by scientists Karl Landsteiner and Alexander S. Weiner. These revolutionary case studies involved rabbits which, when injected with the Rhesus monkey's red blood cells, produced an antibody present in the red blood cells of many humans--the Rhesus factor. The Rhesus factor is an antigen, or more specifically a protein, that exists on the surface of red blood cells.

People with the Rhesus factor, that is, people with the antigen present in their blood, are Rh-positive (or in your case A+). People without the Rhesus factor, that is, people that don't have the antigen in their blood, are Rh-negative. There's no better or worse as far as I know.

Answer 2

A+ is the second most common type of blood, only O+ is more common. The + or - refer to whether your blood has a protien called Rhesus protien in it or not.  This protien was first found in the rhesus monkey.  The majority of people in the world have this protien.  

O+ most Common

A+ second

B+ third

AB+ fourth

If you have type A blood, you can only receive types A and O blood.

If you have type B blood, you can you can only receive types B and O blood.

If you have type AB blood, you can only receive types A, B, AB, and O blood.

If you have type O blood, you can you can only receive type O blood.

Type O blood can be given to anyone with any blood type. That is why people with type O blood are called universal donors.

The reason why it is important to know if you have the protien in your body or not is in case of blood transfussions.  If you do not have this protien and receive a blood transfusion containing this protien your body will build up anti-bodies because it sees it as an invader subsequent transfusions will cause reactions of a severity that can cause death.  

If you have this protien and receive a transfusion from a negative source it will not negatively affect you.

If you are a female negative, and you're pregnant by a positive person there is 50% chance the baby will be positive.  IF this happens you could build up anti-bodies due to placental blood mixing (small quantities).  Subsequent pregnancies from a positive source can have tremendous complications.  Doctors now days have medications to allow a sensitive woman to carry a positive child to term.

Answer 3

The only difference is that A+ means you have the Rh antigen on your blood cells, like most of us, while A- lacks the Rh antigen.

The only medical significance is that there are issues to deal with when an Rh+ woman is pregnant with an Rh- baby.  No blood type is "better".

Answer 4

A+ blood group contains the Rh factor present in 85% people of the world while A- means the absence of Rh factor on the RBCs. There is nothing as such that which of them is better. But Rh factor is the most important thing while giving birth to a child because if the Rh factor of the mother and child are against each other, the antibodies might lead to fatal consequences of the foetus. A blood group people can give blood to either A or people of AB blood group. People of AB blood group can receive blood from every blood group but O- is the rarest of all.

Answer 5

yhe only difference is the Rh factor urs red cells absent this Rh D antigen wich dont show agglutination when tested with anti-D sera.
