Question 1

What types of drug tests do you offer?

Accepted Answer

We offer urine drug testing, hair follicle testing, oral fluid (saliva) testing, and breath alcohol testing (BAT). Each method has different detection windows and use cases — we can help you choose the right test for your program.

Question 2

What is the difference between urine and hair follicle testing?

Accepted Answer

Urine testing is the most common method and detects recent drug use, typically within the past 1–3 days for most substances. Hair follicle testing has a longer detection window of up to 90 days, making it useful for pre-employment screening or when a longer history is needed.

Question 3

Do you offer oral fluid (saliva) testing?

Accepted Answer

Yes. Oral fluid testing is a non-invasive option that detects very recent drug use, typically within the past 24–48 hours. It is increasingly used for post-accident and reasonable suspicion testing due to its ease of collection.

Question 4

Can you test for alcohol as well as drugs?

Accepted Answer

Yes. We provide breath alcohol testing (BAT) using DOT-approved evidential breath testing devices. Alcohol testing can be included in your program alongside drug testing.

Question 5

Can we conduct drug tests at our own facility?

Accepted Answer

Yes. D&D provides Chain of Custody (COC) forms and test kits so your organization can conduct on-site collections. We supply everything needed to ensure the sample is properly documented and legally defensible from collection through laboratory analysis.

Question 6

Are you able to conduct DOT-regulated testing?

Accepted Answer

Yes. We are fully equipped to conduct DOT-regulated drug and alcohol testing under 49 CFR Part 40. This includes pre-employment, random, post-accident, reasonable suspicion, return-to-duty, and follow-up testing for safety-sensitive employees.

Question 7

Which DOT agencies do you support?

Accepted Answer

We support testing for employees regulated by FMCSA (trucking), FAA (aviation), FTA (transit), FRA (railroad), PHMSA (pipeline), and USCG (maritime).

Question 8

What is required for DOT supervisor training?

Accepted Answer

Federal DOT regulations require supervisors of safety-sensitive employees to complete a minimum of 60 minutes of training on alcohol misuse and 60 minutes on controlled substance use. We offer this training on-site at your facility.

Question 9

How do I schedule a test for an employee?

Accepted Answer

Contact us by phone or through our online form and we will coordinate the collection appointment. We serve employers across the contiguous United States and can direct employees to a nearby collection site.

Question 10

How quickly will I receive results?

Accepted Answer

Most results are returned within 24–48 hours for negative results. Non-negative results require Medical Review Officer (MRO) review, which may take additional time. We will keep you informed throughout the process.

Question 11

What is a Medical Review Officer (MRO)?

Accepted Answer

An MRO is a licensed physician responsible for reviewing and interpreting laboratory drug test results. They contact donors to discuss any legitimate medical explanations before reporting a result to the employer, ensuring accuracy and fairness. D&D works with a contracted MRO, so results are reviewed promptly by a qualified physician.

Question 12

Can you manage our company's random testing program?

Accepted Answer

Yes. We can administer a random selection program for your workforce, ensuring the process is unannounced, statistically valid, and compliant with applicable regulations. We handle the selection, notification coordination, and recordkeeping.

Question 13

What testing is required after a workplace accident?

Accepted Answer

Post-accident testing should be conducted as soon as practicable after a qualifying incident. DOT-regulated employers have specific timeframes — 8 hours for alcohol and 32 hours for drugs. We can respond quickly to support your post-accident testing needs.

Question 14

What is return-to-duty testing?

Accepted Answer

Return-to-duty testing is required when an employee who tested positive is cleared to return to a safety-sensitive position. It must be directly observed and preceded by a substance abuse professional (SAP) evaluation. We coordinate this testing as part of a compliant return-to-duty process.
