Laboratory Services

Children's Mercy Patient Lab Medicine

Our clinical laboratories provide inpatient, outpatient and outreach laboratory services for Children's Mercy patients and the greater Kansas City community.

Children’s Mercy Outpatient Laboratory locations provide blood collection services.  We do not collect specimens for respiratory illnesses (Strep throat/Flu/RSV/Pertussis).

Laboratory services policy

The policy at Children's Mercy is to provide outpatient services only when ordered by a practitioner (MD, DO, DDS, DMD, APRN, PA) who is properly licensed and eligible for participation in Medicare and other Federal health care programs. APRNs and PAs orders will only be accepted if the provider holds a Kansas and/or Missouri license.

Direct-access testing or patient-authorized testing is not permitted.

Only written/faxed orders within 30-business days of the date of service or orders which give a specific future date of service will be accepted.

Allergy panel notice

There are many different types of allergy panels available depending on the laboratory offering the service. When we receive panel orders which don't match our panels we will offer the family the option to have 2 tubes of blood collected, which are highly likely to cover what is needed, and follow up on order resolution after the collection. This will require orders on a CMH requisition and may cause a delay in testing.
