DOT Drug Testing Costs in Houston, Texas
Average Cost Range
In Houston, DOT drug testing costs typically range between $45 and $85 per test, depending on several factors. Pricing may vary based on the type of test, service location, and whether testing is done individually or as part of a company program.
Factors That Affect DOT Drug Testing Costs
Several elements influence the final cost of DOT drug testing:

Walk-in vs. mobile testing services

Understanding these factors helps drivers and employers choose the most cost-effective option.
Common Types of DOT Drug Tests and Their Costs
Pre-Employment DOT Drug Testing
Pre-employment DOT drug testing is required before a driver begins safety-sensitive duties. Costs usually fall on the lower end of the price range, especially when performed during normal business hours at a clinic.
Random DOT Drug Testing
Random testing is conducted throughout the year as part of an employer’s compliance program. Pricing is often discounted for companies enrolled in a random testing consortium.
Post-Accident DOT Drug Testing
Post-accident testing may require immediate or mobile services, which can increase the cost slightly due to urgency and coordination requirements.
Return-to-Duty and Follow-Up Testing
Drivers returning after a violation must complete return-to-duty and follow-up tests. These tests follow strict DOT protocols and may involve multiple tests over time, affecting total costs.
Breath Alcohol Testing (BAT) Costs in Houston
In addition to DOT drug testing, some situations require Breath Alcohol Testing (BAT). BAT costs in Houston generally range from $40 to $70, depending on whether testing is conducted in-clinic or onsite.
BAT is commonly required for:
-
Post-accident situations
-
Reasonable suspicion testing
-
Random alcohol testing programs
How to Save Money on DOT Drug Testing
Choose Walk-In Clinics
Walk-in DOT clinics typically offer the most affordable testing options. They eliminate travel and setup fees associated with mobile testing.
Use Mobile Testing for Groups
While mobile testing may cost more per visit, it can reduce downtime for companies testing multiple employees at once, saving money overall.
Join a Random Testing Consortium
Employers who join a DOT random testing consortium often receive reduced testing rates and administrative support.
