We began using American Drug and Alcoholic Diagnostics for all of our drug screening needs in 2018. They are very accommodating with scheduling pre-employment and random screenings. Best of all, results are back in under 48 hours. Their team handles compliance perfectly, which saves our HR department a massive amount of time. Highly recommended for any business.

They are always, on-time, professional with us and our employees and knowledgeable of all of the rules and guidelines to always ensure we are in compliance. Whenever I call/email to ask a question, they are quick to respond and super helpful to our company. We would recommend them for all of your drug and alcohol compliance needs!

Thanks, Kirk!
We have used American Drug and Alcohol for years. We would highly recommend them. With all the changes in FMCSA and motus, there have been times when we had no idea as to what to do. Their highly trained personnel guided us through the necessary process. Don't know what we would do without them!
