Dilute Specimen and How it Affects Drug Screening
Drug screening is a critical component of maintaining workplace safety, productivity, and compliance with regulations, especially in industries requiring DOT compliance. However, one issue that can arise during drug testing is the occurrence of dilute specimens — samples with higher-than-normal water content, which can complicate the testing and decision-making process. This blog post dives deep into dilute specimens, how they affect drug screening, and how Workplace Screening Intelligence can help you manage your employment screening and compliance needs with ease.
What is a Dilute Specimen?
A dilute specimen occurs when the urine sample provided for a drug test contains a higher concentration of water than normal. This can happen naturally due to an individual consuming large amounts of water before their test or deliberately in an attempt to skew results. Dilute specimens can affect both DOT-regulated drug tests and NON-DOT drug tests, requiring additional steps to ensure accurate results.
When a test comes back as dilute, the lab cannot determine if the individual was attempting to mask substances in their system or if they naturally hydrated excessively. This lack of clarity can create compliance, hiring, and workplace safety challenges for employers.
Why are Dilute Specimens Important to Address?
For employers, particularly in safety-sensitive industries, properly addressing dilute specimens is crucial for several reasons:
- Workplace safety: A dilute specimen could potentially mask drug use, putting your workplace at risk.
- Compliance: For DOT-regulated industries, adhering to federal guidelines is non-negotiable. A failed DOT drug test or improper handling of a test results result in fines, penalties, or increased scrutiny.
- Integrity of Hiring Decisions: Hiring an individual with an unclear drug test result could lead to liability issues and risks down the line.
- It is important to address how you will address dilute specimen in your DOT policy. Simply you will decide to either accept dilute specimens or require a repeat test. You can also decide if for pre-employments and/or current employee testing.
Having a partnership with a Medical Review Officer (MRO) is critical in such cases. An Medical Review Office reviews drug test results, verifies any underlying medical conditions or prescribed medications, and ensures proper documentation for a drug test chain of custody form to secure compliance and clarity.
Types of Drug Tests and Screening Options
When it comes to implementing drug testing in your workplace, employers typically need to decide between DOT-regulated drug tests and NON-DOT drug tests. Understanding the differences and available testing panels is important for ensuring compliance and covering workplace needs.
Regulated Drug Test vs. Non Regulated Drug Test
- DOT Regulated Drug Tests: Mandated by the Department of Transportation (DOT) for safety-sensitive positions in industries like trucking, aviation, and railroads. If you’re searching for a “DOT drug test near me” these tests are likely to be required. Regulated Drug test must be completed on a Regulated Drug Test form or it may not count towards compliance.
- Non Regulated Drug Tests (NON-DOT): Used by employers in industries not governed by DOT regulations. These tests can be customized based on the employer’s specific needs. Employers often choose such screenings for random testing, pre-employment, post-accident, or reasonable suspicion testing.
Common Testing Panels
- 5 Panel Drug Screen: Covers basic substances including marijuana, cocaine, amphetamines, PCP, and opiates.
- 10 Panel Drug Test: Includes the same substances as the 5-panel test but adds common prescription drugs like benzodiazepines, barbiturates, methadone propoxyphene and Quaaludes or Methaqualone.
- Specialized Drug Screens: Target specific substances, including synthetic drugs like K-2 spice and Buprenorphine, or substances like fentanyl and tramadol for workplaces with specific risks.
Alternate Methods of Drug Testing
- Hair Follicle Drug Test: Provides a longer detection window as it can trace drug use back 90 days or more.
- Oral Fluid Drug Test: Detects recent drug use within the past 24-48 hours, often used for post-accident testing, reasonable suspicion test or pre-employment drug screening.
Dilute Specimens in DOT vs. NON-DOT Testing
Other factors to note:
- DOT Testing Requirements: The DOT employers decides how to handle dilute testing protocol and should be documented in DOT drug and Alcohol Testing policy.
- NON-DOT Testing Scenarios:** Employers can set their own policies for handling dilute specimens, though it’s best to clarify these in a written drug and alcohol policy for both DOT and NON DOT testing to ensure consistency and fairness.

Frequently Asked Questions
What is NON-DOT and why does it matter?
Non-DOT refers to industries or roles that are not regulated by DOT standards. While NON-DOT employers may not need to meet strict federal requirements, maintaining a robust testing program is still critical for the safety and productivity of your workforce.
What happens if an employee fails a drug screen?
If an employee fails a drug screen, particularly under DOT, they will need to undergo the Return-to-Duty test and follow-up testing as outlined in their company’s or the DOT Random Testing Consortium policy.
Can I order a test for any substance, like shrooms?
Yes. Many specialized drug screens are available that target specific substances. Whether you’re screening for less common substances or requesting a buprenorphine or ketamine drug test, we can tailor solutions for your needs.
How far back does a hair follicle drug test go?
It can detect drug use up to 90 days or more from the test date, making it a reliable tool for pre-employment screening and random testing scenarios like those for the Ohio BWC 15% Random Testing Consortium.
Can I use a hair follicle drug test for suspicion-based testing?
NO , this test is not a good test for reasonable suspicion testing as it takes 7-10 days for the drug to grow within the hair shaft. Oral Fluid or Urine are better suited for Reasonable Suspicion Testing and Post-Accident Tresting.
