Labcorp

When enabled for your team, Junction uses Labcorp AccuDraw to generate a specimen collection guide PDF for Labcorp orders using at_home_phlebotomy, walk_in_test, or on_site_collection modalities. This guide is separate from the requisition and is intended for phlebotomists or clinical staff collecting and preparing the specimens. Contact Junction support to enable collection instructions and PDF access.

​
What the guide contains

Junction generates the guide from the order’s Labcorp test codes and selected lab account (see Lab Accounts), so the handling and shipping instructions reflect the account used for that order. Based on the instructions returned by AccuDraw, the PDF includes:
  • Required collection containers and quantities, with tube images when available.
  • The collection sequence, container sizes, expected sample yields, and special draw instructions.
  • Transport containers, storage temperatures, processing volumes, and shipping details, including destination labs when supplied.
  • The Labcorp account and test codes and names covered by the guide.
If AccuDraw returns instructions for only some tests, the PDF is labeled as a partial guide and lists the uncovered tests with guidance from Labcorp.

​
When instructions are generated

After the order is created, Junction attempts to generate and save the guide before submitting the requisition to Labcorp. For orders with a future activate_by date, generation is deferred until the order is due for submission. These guides are not automatically generated for sandbox orders or testkit orders. A failure to generate the guide does not prevent requisition submission. A successfully created order or requisition therefore does not guarantee that collection instructions are available.

​
Downloading and using the guide

Retrieve the saved PDF with Get Collection Instructions PDF for Order: GET /v3/order/{order_id}/collection_instruction_pdf. The endpoint returns application/pdf when the guide is available and 404 when the order has no saved guide. Downloading does not generate or regenerate instructions. For at-home phlebotomy appointments, Junction attaches the saved guide to the provider’s appointment when available. Booking does not call AccuDraw again and can continue if the guide is unavailable.
