Redraw Workflows in Junction

Junction now supports improved redraw workflows with linked redraw orders, new requisitions, automated patient communications, and enhanced redraw tracking throughout the dashboard.

This update is designed to reduce manual coordination, improve operational clarity, and create a more reliable redraw experience for both patients and care teams.

Ready to implement Order Transactions to track redraws and their associated original orders?

Overview

Historically, redraw workflows often relied on:

• manual patient outreach

• operational coordination with support teams

• reuse of the original requisition

• limited redraw lifecycle visibility

With this update, redraws are now handled as structured workflows within Junction.

When a redraw is initiated, Junction can:

• create a new linked redraw order

• generate a new requisition for the redraw

• automatically send updated patient communications and instructions

• maintain association with the original order

• track the redraw independently throughout its lifecycle

How redraw workflows now work

With improved redraw workflows:

1. Junction creates a new linked redraw order within the order transaction

2. A new requisition is generated for the redraw and a webhook is sent

3. Updated redraw communications are sent to the patient automatically (if Junction communication settings are turned on)

4. The redraw is tracked independently while remaining linked to the original order

This creates a cleaner and more operationally scalable redraw process.

How redraws work in Junction

1. Missing results are identified

When lab results return with one or more missing biomarkers due to a lab error in a final result, Junction determines that a redraw is available.

Lab errors do not typically include: insufficient sample collection and phlebotomy or clinic storage problems

2. A redraw order is created automatically

Junction:

• Creates a new lab order for the redraw

• Generates a new requisition containing only the missing biomarkers

• Sends automated email and SMS communications to the patient (if enabled for that team)

3. Orders are grouped into a single patient journey

The original order and redraw order are linked together under an order transaction, representing the full lab journey for that patient.

4. Results are delivered as one complete set

Once the redraw is completed:

• Results from the original draw and redraw are merged

• You receive a complete result set for the patient

Key concepts

Order Transaction

An order transaction represents the full patient lab journey.

One transaction includes:

• One initial lab order

• Up to one redraw order

This is the recommended object to track for:

• Overall status

• Final, complete results

Best practice: Track patient progress using the order_transaction_id, rather than individual order IDs.

Orders

Each lab visit is represented as its own order:

• Initial order → first lab visit with original requisition

• Redraw order → follow-up visit with a new requisition

Each order:

• Has its own requisition

• Has its own lifecycle

• Is linked to the same transaction

Orders include an origin field (initial or redraw) to clearly identify redraws.

Results behavior

Unified results

• Results are returned at the transaction level as a single, combined set

• If a biomarker appears in both the original draw and the redraw:

  • The redraw result takes precedence

• Individual order-level results remain available if needed

Result access

You can retrieve:

• Combined results in JSON

• Combined results in PDF

This eliminates the need to manually merge results across lab visits.

Patient experience

With redraws AND Junction communications enabled:

• Patients are automatically notified when a redraw is required

• Patients receive a new requisition for their redraw visit

• There’s no need for patients to explain missing biomarkers at the lab

• The redraw feels like a continuation of the same test, not a restart

Without Junction communications enabled, your team should utilize the available API webhooks and endpoints to customize email, SMS, etc.

What’s supported today

• Walk-in lab redraws

• Quest (and Sonora-Quest), Labcorp, and Bioreference

• One redraw per patient journey

• Unified results delivery

Current limitations

• Multiple redraws within the same patient journey are not supported

  • If a second redraw is required, a new order should be created

• Mobile phlebotomy redraws are not supported yet

• Junction Orders and Results dashboard are currently order-based

  • Transaction-level views are planned for future updates

Getting started

To use redraws:

1. Review the API documentation

2. Ask your CSM to enable redraws in sandbox

3. Validate webhook handling and result retrieval

4. Ask your CSM to enable in production once ready

Your Junction CSM will guide you through setup and best practices.

Summary

Junction’s redraw solution replaces manual, error-prone redraw workflows with an automated, patient-friendly approach that:

• Reduces patient friction

• Simplifies operations

• Delivers complete results reliably

• Scales cleanly as your testing volume grows
