Finding out your blood group is comparatively simple. You can:
have a test done by your doctor
get the knowledge when donating blood
take an at-home blood test
How does one determine what blood group you are?
Your blood group is comprised of two blood groups: ABO and Rh.
Blood types are supported antigens on the surface of your red blood cells. An antigen may be a substance that triggers an immune reaction by your body against that substance.
ABO blood types group your blood by the existence of specific antigens:
*Type A has the A antigen
*Type B has the B antigen
*Type AB has both the A and B antigen
*Type O doesn’t have either the A or B antigen
Once your ABO blood group has been determined, it is often further defined by identifying the Rhesus (Rh) factor:
Rh-positive. If you’ve got Rh antigens on the surface of your red blood cells, you’ve got Rh-positive blood.
Rh-negative. If you don’t have Rh antigens on the surface of your red blood cells, you’ve got Rh-negative blood type.
By including the rhesus factor, the 8 most prevalent blood types are often identified: A+ or A-, B+ or B-, AB+ or AB-, and O+ or O-.
How is blood testing typically done?
At your doctor’s office, a clinical laboratory, or a hospital, a phlebotomist (someone trained to draw blood) will use a needle to draw blood from your arm or hand.
That blood is going to be mixed with antibodies and therefore the reaction is going to be noted. for instance, if your blood cells clump together (agglutinate) when mixed with antibodies against B blood, you’ve got A blood.
Next, your blood is going to be mixed with an anti-Rh serum. If your blood cells respond by clumping together, you’ve got Rh-positive blood.
How am i able to determine my blood group at home?
In at-home diagnosis tests, they typically ask that you simply prick your finger with a lancet and put drops of your blood on a special card.
After putting the blood on the card, you’ll observe the areas where blood clumps or spreads out, then match those reactions to an included guide.
Some home testing kits have vials of fluid for your blood, as against a card.

How to determine your blood group for free of charge
One way to seek out your blood group is to donate blood.
If you donate to community blood supplies, ask the staff if they’ll be ready to tell you your blood group. Many donation centers are ready to provide that information.
Typically you won’t get your blood group immediately and should need to wait a couple of weeks, as blood isn’t commonly tested directly.
Can blood group be determined without drawing blood?
About 80 percent Trusted Source of people secrete blood type antigens in other bodily fluids, like saliva, mucus, and sweat. This group of individuals is mentioned as secretors.
Secretors can have their blood group determined by saliva or other liquid body substance test.
Blood typing kits using saliva are available online but are typically costlier. Using one among the kits, you’ll first learn whether or not you’re a secretor. If you’re, then you’ll be ready to determine your ABO blood group.
There are a variety of the way you’ll determine your blood group, including:
*visiting your doctor
*going to a hospital or clinical laboratory that tests blood
*getting a home testing kit
If you’re within the category of individuals who secrete blood type antigens in other bodily fluids, you’ll determine your blood group without having blood drawn.
