What is Blood Type?
Your blood type is determined by the presence or absence of specific antigens on the surface of red blood cells. Antigens are molecules or structures that can be bound to antigen-specific antibodies.
Basically, if your antibodies bind with antigens on your blood cells then it triggers an immune response called agglutination. It’s deadly.
Depending on the type of antigens you may or may not have on your red blood cells determines your blood type.
There are two kinds of antigens that are on the red blood cells or floating around in the plasma. Mixing and matching this gives us 4 primary blood types:
Type A = A antigens are on red blood cells and B antibodies are in the plasma
Type B = B antigens are on red blood cells and A antibodies are in the plasma
Type AB = Both A and B antigens are on red blood cells and neither A or B antibodies are in the plasma
Type O = Neither A or B antigens are on red blood cells and both A and B antibodies are in the plasma
Now, step it up with one more variable: Rh Factor.
In 1937, Alexander Weiner and Karl Landsteiner discovered a new variable in blood type named the rhesus blood type, or Rh factor.
The rhesus protein lives on the surface of red blood cells alongside the A or B antigens. The rhesus protein is often called the D antigen. Most people have the rhesus protein (approximately 85%) and some do not.
This discovery doubled the number of blood types giving us the 8 blood types we reference today.
Which gives us the positive or negative that goes behind the A, B, AB, and O blood type names.
Why Does Blood Type Matter?
Blood transfusion, sharing blood, is a life-saving technique used all over the world for thousands of different reasons.
Sharing your blood gives someone else a chance at living. Most commonly are cancer patients, surgery patients, accident victims, organ transplant recipients, and burn patients.
Blood transfusions are a life-saving technique first successfully used in 1818 (or 1829). An English obstetrician, James Blundell, performs the first successful blood transfusion for a patient to treat postpartum hemorrhage. The exact dates are up for debate.
He saw many of his patients die during childbirth and determined to create a remedy.
Bundell extracted four ounces of blood from the patient’s husband with a syringe and transfused it into the patient.
But he wasn’t the first to try. In 1628 the circulation of blood was discovered by William Harvey. The first blood transfusion attempts begin shortly after.
The patient can be young or old, rich or poor, and any race. Your blood can help keep them alive in a time of need.
How do you find out your blood type?
Well, you can find out your blood type for free by donating blood.
Boom. Answer. Done.
Home test kits are available on Amazon… But, the reviews are not kind. Go donate some blood and ask them to test it real quick.
