About the Test
Determining your blood type can help inform medical treatment compatibility and avoid various complications. This blood type test (or ABO/Rh test) identifies your blood group (i.e., A, B, AB, O) and Rh factor (i.e., positive, negative). Your blood type is inherited and based on the presence or absence of certain sugars (ABO blood group antigens) or proteins (Rh antigen) attached to the surfaces of your red blood cells.

FAQs
Having Rh-negative blood means that you do not have a specific protein on your red blood cell membrane. Rh-negative blood doesn't affect your overall health. However, if you are pregnant and Rh negative, you may need an injection of a blood product called “Rh immune globulin” during your pregnancy. Without this treatment, your immune system may treat your baby’s Rh positive cells as if they were foreign, where your antibodies may attack the fetus’ circulating red blood cells.
Yes, universal blood donors have type O, Rh-negative blood (O-), which is compatible with all blood types. The red blood cells do not contain antigens or the Rh factor to interact with a recipient's antibodies.
Universal recipients have type AB, Rh-positive blood (AB+). Their bodies recognize A, B, and Rh antigens as their own, allowing them to receive red blood cells of any ABO or Rh type
When blood cells are transfused that aren’t compatible with the recipient’s blood type, the immune system recognizes them as foreign invaders and responds by attacking and destroying them (incompatibility). For example, if a person with type A blood received a type B or AB blood transfusion, an ABO incompatibility response would occur. Rh incompatibility can occur when a pregnant woman has Rh-negative blood, and her baby has Rh-positive blood. In addition, a person who is Rh-positive can receive blood from someone who is Rh-negative, but those with a negative blood type cannot receive blood from those with a positive blood type.
Universal recipients have type AB, Rh-positive blood (AB+). Their bodies recognize A, B, and Rh antigens as their own, allowing them to receive red blood cells of any ABO or Rh type

Yes, there are many variations of blood types, but these are the 8 most common:
- A+
- A-
- B+
- B-
- AB+
- AB-
- O+
- O-
There are more than 600 blood markers outside the ABO blood system. They have been used to identify over 30 rare blood types. These types of blood can be found in 1 out of every 1,000 people (or fewer). Some of these rare blood groups include the1:
- Duffy blood group
- Kell blood group
- Kidd blood group
- Lutheran blood group
But there's one blood type that stands out from the rest—the Rh-null blood type. With fewer than 50 people known to have this blood type, it's truly rare and sometimes referred to as “golden blood.”
The questhealth.com Blood Type Test only identifies which of the 8 common blood types you have.
