Answers to Your DOT Drug Screen Frequently Asked Questions

Drug Screen FAQ

Drug screening is an important part of the hiring process. It is also required by anyone seeking their DOT CDL license. While the need for drug screening is widespread, there are some frequently asked questions regarding drug screens that we are asked throughout the process.

To help you, here are some of the most common DOT drug screen FAQs:


Are drug screens performed in your office?

Yes, we collect specimens for both DOT and non-federal drug screens.  They are then sent out to a certified laboratory, MedTox.  Dr. Hanahan is a certified MRO (Medical Review Officer) and reviews the results when they arrive.

How long does it take to receive results?

We usually receive results within 3-4 business days, depending on the time of day the employee comes in for the screen.  If the delivery for the day has already gone out, it could take an extra day for transport.

How can I schedule a drug screen?

No appointment is needed, simply call the office to check the seasonal hours.  We are open from 8:00am – 4:00pm every day from October thru March.  We are closed on Wednesdays April thru September.

How do I receive my results?

If the drug screen is initiated by a company, the company representative will receive the results after the Dr. has reviewed them.  If a patient has initiated the drug screen, we will report the results to you via your preferred method.

I am a CDL holder, how often do I need to be drug screened?

According to DOT guidelines, your employer must get a pre-employment drug screen on you.  After that screens can be done for a variety of reasons: random, post-accident and reasonable suspicion.  

What if I am on medications that will turn up in my drug screen?

When a drug screen comes back positive for any substance, Dr. Hanahan (MRO) will contact you to discuss the possible causes.  If you have a valid prescription you will be required to have a copy of the prescription faxed to our office or you will asked to bring it in.  At that time the Dr. will determine if that is the cause of the result.  If the prescription is valid, the test is then reported as a negative.  

What drugs are screened for in a DOT panel?

We screen using the NIDA5 panel which includes: Marijuana (THC), Opiates ,  Cocaine,  Amphetamines  and Phencyclidine (PCP).

What drugs are screened for in a non-federal panel?

The non-federal can be customized depending on your company policy.  Typically, we run a 10 panel test which screens for:  Amphetamines, Barbiturates, Benzodiazepines, Cocaine, Opiates,  Oxycodone, Phencyclidine (PCP), Marijuana (THC), Methadone,  and Propoxyphene.

I’d like to screen my employees randomly on a quarterly basis.  Can you help with this?

Absolutely!  If you are a trucking company, we can enroll you in our DOT Consortium and you will be notified by HCFB if and when any of your drivers are pulled.  If you are not DOT and would just like your own employees in a random pool, we can do that as well!  You can give us the parameters of your testing program and we will notify you quarterly who has been selected and will need to be screened.  These programs play a crucial role in maintaining a drug –free workplace and in many instances, qualify for a discount in your BWC policy rate.  Please contact our office at (440) 354-4747 for more information on setting up your program.
