Total Protein: About Your Child's Test

What is it?

A total serum protein test measures protein in the blood. It also measures the amounts of two major groups of proteins: albumin and globulin.

Why is it done?

Albumin is tested to:

• See how well the liver and kidneys are working.
• Find out if your child's diet contains enough protein.
• Help find the cause of swelling of the ankles or belly. The test can also find the cause of fluid that builds up in the lungs. This fluid may cause shortness of breath.

Globulin is tested to find out how well your child's body is able to fight off infection.

How do you prepare for the test?

In general, you won't need to prepare before your child has this test. Your doctor may give you some specific instructions.

How is the test done?

A health professional uses a needle to take a blood sample, usually from the arm.

How long does the test take?

The test will take a few minutes.
