Order Results API

The Order Results API lets you retrieve Labcorp test results on existing lab orders. The full endpoint reference, with request/response schemas, is in the Order Results API reference.

What you can do

• Look up test results on existing orders that have been accessioned (processed and published).

Get started

1. Authenticate to the gateway and confirm connectivity with the gateway health check. The Order Results endpoint is reached through the gateway with your bearer token; you do not authenticate to the Order Results API directly.
2. Call GET / with a query string containing the accountNumber, controlNumber, sendingFacility, and sendingApplication which are used to identify the order results.
3. Explore every endpoint in the Order Results API reference.

Abnormal codes

The interpretationCode field on each result maps to a Labcorp abnormal code:

Critical	<
Abnormal	A
Critical	AA
