Blood type tests are used to check what blood type your child has. Blood is "typed" according to whether certain markers, called antigens, are on the surface of red blood cells.
The ABO test is a common blood type test. The ABO test shows which of four blood types your child has: A, B, AB, or O. These letters stand for which kind of antigen is on your child's red blood cells. If your child's red blood cells don't have either the A or B antigen, your child has type O blood.
A blood type test is done:
You don't need to do anything before your child has this test.
A health professional takes a sample of your blood.
Follow-up care is a key part of your child's treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse call line if your child is having problems. Ask your doctor when you can expect to have your child's test results.
