How do I prepare for a DOT Physical? 

Get a good night’s sleep, eat a light meal, stay hydrated, and bring any required medical records or a list of medications. Control your blood pressure if possible before the exam.  If you use a CPAP, bring your Compliance Report.  If you have Diabetes, bring your most recent blood work results and letters from your Physician regarding neuropathy and your Eye Doctor regarding retinopathy. 

Can I eat or drink before a drug test? 

Yes, drug testing does not require fasting.  However, please avoid excessive water right before a urine test, as overly diluted samples may require recollection. You should not consume more than 40 ounces of water in the few hours prior to testing.  You do not need to enter the collection site until you are ready to provide a specimen.

Will my results be confidential? 

Yes. We follow strict privacy guidelines. Results are only released to authorized parties (e.g., your employer for workplace testing or as directed for legal paternity tests).
