About Us
DOT Safety Consultants
DNA Screening Services, LLC is a locally owned business that was founded in 2015. We are based out of the Rio Grande Valley area of Texas, but we can work with agencies nationwide.
Why Choose Us
We offer the convenience of on-site services such as drug and alcohol testing with quick turnaround times of 24-48 hours. Our test results are always accurate, and we do not believe in offering estimations when we know we can give you the best possible diagnosis results.
Safety Consultation
We are DOT Safety consultants. Our team knows the importance of handling and how important it is to handle the tests properly. We take a lot of precautionary measures to keep our roads safe and ensure the safety of transportation businesses and drivers.
