Antinuclear Antibodies: About Your Child's 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.

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.
