Laboratory services

The staff at Children's laboratories specialize in tests for children, and we understand the stress a test can cause for you and your child. We use pain management techniques and therapies, such as pet therapy, to provide as stress-free an experience as possible.

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. Please follow these instructions.

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

What should I bring to the outpatient laboratory?

  • Test order requisition or physician prescription, if provided by your child's doctor
  • A current insurance identification card
