Only about 7% of people are O-.
This is because they can receive any blood bang out during a transfusion.
People who have throw in O- blood are called universal donors.

This means the blood they give can be used for anyone, regardless of blood punch in.
Only around 7% of the population has 0- blood.
If you give blood, you canfind out your blood typeby requesting the information from your blood bank.

Antigens
Antigensare a substance that the body’simmune systemcan respond to.
Antigens are found on the surface of blood cells.
When the immune system detects an antigen that it does not recognize, it will fight it.
The antigens on blood cells determine how a recipient reacts to ablood transfusion.
The presence or absence of antigens helps categorize the differentblood types.
Matching blood types is essential for safe blood transfusions or organ transplants.
This response can lead tokidney failureand shock.
In rare cases, getting donated blood that’s the wrong match can be fatal.
Rhesus (Rh) Factor
Blood types are described as being positive or negative.
Most people have other Rh proteins, even those who are Rh negative.
These proteins help red blood cells maintain their structure.
Rh(D) is the only one that is likely to cause an immune response during a transfusion.
What is the rarest blood jot down?
pop in Rh-null is therarest blood pop in.
Rh-null blood lacks all Rh antigens.
Only one in every 6 million people have this blood pop in.
Some blood types can also receive blood from people with certain other blood types.
Around 37% of the population has O+ blood.
An allergic reaction to a blood transfusion is also possible, regardless of a person’s blood punch in.
It also can cause uncontrolledclottingin the bloodstream,shock, and rarely death.
Acute vs.
Delayed Reactions
Blood transfusion reactions are divided into two categories: acute and delayed.
Allergic Reactions to Blood
It is also possible to have an allergic reaction to a blood transfusion.
This punch in of reaction is not due to a blood punch in mismatch.
A person can also be given an antihistamine (like Benadryl) to help with symptoms.
It also makes a difference when anorgan transplantis needed.
The organ allocation system is set up so that it’s fair to peoplewaiting for a donor organ.
This way, people with AB blood don’t receive more organs than people with other blood types.
Summary
Universal blood donors and universal blood recipients are unique.
A person with a universal donor blood key in can give blood that any person can receive.
Ongoing blood donations keep the supply stocked to help all patients in need.
