Antinuclear Antibodies: About Your Child's Test

What is it?

An antinuclear antibody (ANA) test is a type of blood test. It measures the amount of certain types of autoantibodies in the blood. Autoantibodies are types of antibodies that target and react to your child's own body (called an autoimmune reaction).

Why is this test done?

An ANA test is done to help find problems with the immune system. This can include juvenile rheumatoid arthritis, systemic lupus erythematosus, Sjogren’s syndrome, and mixed connective tissue disease.

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 several minutes.

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 advice line (811 in most provinces and territories) if your child is having problems. Ask your doctor when you can expect to have your child's test results.
