Appointments and Locations

We offer specimen collection at our Test Referral Center on our main campus at 3333 Burnet Ave. and at many neighborhood locations. Hours vary by location. See locations and hours. 

Blood draws are performed on a walk-in basis, unless otherwise instructed by your provider.  

Some tests do require you to schedule an appointment for your blood draw (glucose tolerance, sweat chloride, platelet aggregation, etc.). If you need one of these tests, please call the Scheduling Center at 513-636-3200. 

Yes, Cincinnati Children’s requires an order from your healthcare provider for all lab work. The orders can be brought in by the patient, faxed to the laboratory by the provider, or entered electronically by the provider.

Please bring:

  • Your child’s insurance card
  • A valid photo ID
  • The doctor’s order, if it wasn’t sent electronically

Test Preparation and Results

Some tests require fasting (no food or drink for a certain period). Your child’s doctor will provide instructions if fasting is needed. If you're unsure, contact the ordering provider.
Our labs process specimens 24 hours a day, seven days a week. Some lab tests may take longer to perform than others. Please consult with your provider on how quickly you should expect to receive your results. 

Results are typically available through MyChart or from your child’s provider. If you don’t see results within the expected timeframe, contact your provider’s office. Learn more about MyChart.
