About CRSP

What is CRSP?

CRSP is a technology and notification service that publishes randomized daily colour information according to calendars established for participating physicians.

Users compare the daily colours published through CRSP with the colour assigned to them by their physician. When an assigned colour appears, the user follows the testing instructions provided by their physician.

Testing may include, but is not limited to:

  • Urine testing

  • Blood testing

  • Hair testing

  • Breath testing

  • Other forms of biological screening determined by the physician or monitoring professional

EPIC Recovery does not assign colours, determine testing requirements, collect biological specimens, or receive laboratory results.

How CRSP works

1. Receive your information

Your physician provides your assigned colour, testing instructions, and CRSP Authentication ID.

2. Enrol online

Create or access your EPIC Nexus account, enter the Authentication ID provided to you, and complete the annual CRSP enrolment.

3. Set up notifications

Add EPIC Nexus to your smartphone home screen, enable push notifications, and add CRSP’s email address to your approved or safe senders list.

4. Check CRSP on testing days

Daily colour information is scheduled to be published shortly after 12:01 a.m. on applicable testing days.

Notifications are provided as a convenience. Users remain responsible for opening EPIC Nexus and checking the daily colours, even if an email or push notification is delayed or does not arrive.

Before you enrol

You will need:

  • A smartphone with internet access

  • A current email address

  • The Authentication ID provided by your physician

  • Your assigned colour and testing instructions

  • A valid payment method

CRSP does not store your assigned colour. You are responsible for remembering the colour provided by your physician and comparing it with the daily colour information.
