Laboratory services

What do we need to do to prepare for the test?

Your physician should provide you with special instructions to prepare for the test, including whether your child needs to fast before the test. If the test requires specimen collection at home, your physician will provide specific instructions for storage and transport.

You and your child can watch this video explaining what it is like to get your blood tested at Children's:

*Disclaimer: This video does show the butterfly needle and entire procedure. Caregivers, please watch first to decide if the video is appropriate for your child.
