Referring Patients for Laboratory Testing
The laboratory performs testing based on requests from persons authorized by law to write laboratory test orders (i.e., physicians, PAs and ARNPs).
The laboratory utilizes consistent procedures to ensure appropriate order and specimen receipt, identification, assessment, test order accessioning and accurate billing.
Community providers must provide written orders via a laboratory requisition or a prescription form. Paper orders for laboratory testing will contain the following elements for acceptance:
- Name and address (if outside of Seattle Children's) of physician or legally authorized person ordering the test
- Patient identification utilizing at least two unique identifiers (full name and medical record number or date of birth)
- Patient sex, when appropriate
- Patient date of birth, when appropriate
- Orders for specific laboratory tests
- Time and date of collection, when appropriate
- Source of specimen, when appropriate
- Clinical information, when appropriate
- Medical necessity (ICD-10 codes) – required
All unclear, vague or illegible orders will be clarified with the ordering provider before acceptance.
If the medical necessity information is absent from the initial written orders, the laboratory will utilize a "fax-back" system including a REQUEST FOR ICD-10 form to clarify orders and/or obtain required information.
If the "add on" phone order is received from a community physician, the form will be "faxed back" for signature and medical necessity information. Phoned orders will be transcribed and read back to verify accuracy.
