Weld County Pretrial Drug Testing: How the Sentry System Works

Published by UA Near Me. Last updated 2026-10-14.

If you are on pretrial supervision in Weld County, Colorado, drug and alcohol testing can be one of your release conditions. This guide explains what Weld County itself publishes about how that testing works through the Sentry system, who to contact, and what to do on a day you are required to test. Everything below comes from Weld County's own pages and collection-site list, linked at the bottom.

What Weld County Pretrial Services does

Weld County describes Pretrial Services as a program with three key functions: collecting and analyzing defendant information, recommending release conditions, and monitoring released defendants. Pretrial Specialists are responsible for the daily supervision and monitoring of defendants released into the community. The county lists drug and alcohol testing among the common conditions of pretrial supervision, alongside attending all court dates and abiding by the law.

How testing works through Sentry

Weld County uses the Sentry system for drug testing. The county's Defendant Information page lists a Sentry call line and a Sentry website. Your Pretrial Specialist and the court set your testing requirements, so follow the instructions you were given at release.

Weld County's published list of approved collection sites gives these rules for testing days:

  • If you are required to test today, you must report to one of the approved collection sites that same day.
  • There are no next-day services and no make-up tests.
  • You may submit a sample at any approved collection site. It is your responsibility to work out in advance which site will work best for you on any given day, because sites vary in cost, business hours, and policies.
  • When you report, tell the site that you are on Weld County Pretrial Services supervision and the Sentry system.
  • If you run into problems, call your Pretrial Services Specialist directly and listen for their extension.

Where to test

Weld County publishes a list of approved collection sites across five regions: Denver Metro, Northeastern, Southeastern, Mountain, and Western. We have reorganized the county's list by region in a separate guide, and our testing-site pages list the Colorado sites we cover, with addresses and phone numbers.

Calling the Sentry line every day

If your supervision uses the Sentry system and you have to call a hotline each day, UA Near Me can make that call for you. We call at the time you choose, retry if the line is busy, and send you the recording in full by text and email so you can hear your result yourself.

This guide is general information, not legal advice. Your supervising officer or Pretrial Specialist and the court decide your conditions, so confirm anything specific to your case with them.
