Blood Type Test (ABO, Rh)

Also Known As

ABO Group and Rh Type, Blood Group, Rh Factor

The Purpose of Blood Type Testing

Blood type testing provides essential information that’s used in many medical situations. Blood types are divided into three groups–A, B, and O–based on the antigens, or proteins, in red blood cells. Additionally, blood is categorized by whether it has a Rhesus, or Rh, factor, which refers to a substance on the surface of red blood cells. Blood is either Rh positive or Rh negative. So someone who is A negative has type A blood without an Rh factor.

A test for blood type is common and can be used for:

• Blood transfusions
• Detecting Rh immune globulin candidacy for prenatal and postpartum individuals as well as potential ABO hemolytic disease in newborns
• Special blood type-based diets

What Does the ABO Rh Test Measure?

The blood group test will determine your blood type by detecting antigens in your blood. You will have either A or B antigens, both antigens (blood type AB), or no antigens (type O). The test will also look for the presence of Rh factor.

Who Should Take an ABO Rh Blood Test?

This test is recommended for anyone who:

• Wants to learn their blood type for general health knowledge
• Needs to undergo prenatal testing
• Will have surgery or a blood transfusion
• Follows a blood type diet plan for weight loss

ABO/Rh Test Preparation

No special preparation is required for a blood typing test.
