Urine Drug Screens

Edit

There are screening panels described below, with the option to add-on confirmatory testing.

How to order:

  1. If ordering urine drug testing for pre-employment only, order "Urine Drug of Abuse"
  2. If ordering urine drug testing for stable patients on chronic opioid therapy, buprenorphine treatment for opioid use disorder, or for patients who might be using other substances and a shared decision has been made to check a urine toxicology for safety and education, order "Monitor Screen 14-Drug Class Profile"

Unexpected screening results:

If you receive an unexpected result from the screen panel and wish to rule out a false negative/positive, please add on the confirmatory test for the specific drug - place the order for the drug you want to confirm (see individual list below) and select Add-On (under Priority).

In general, screen first, confirm only if needed:

Please order the screening tests first followed by add-on confirmation and not just the individual confirmatory tests.

The reason for this is two-fold:

  1. Safety: You can screen for other substances that may affect ongoing treatment. Of note, cannabis is commonly used by our patients and it being positive on the panel is rarely a reason to impact clinical management; unfortunately it is part of the LabCorp panel and cannot be removed.

  2. Effective use of resources: Screening panel results are usually sufficient enough for clinical decision-making; confirmatory tests are more costly and time consuming

When to order confirmatory testing WITH screening test: When there have been a history of discordant results (e.g. negative screening immunoassay, positive confirmatory or vice versa) or there is another reason to obtain quantitative results (versus qualitative).
