What Is Blood Drug Testing?
Blood drug testing is one of the most accurate methods of detecting the presence of drugs or alcohol in the system. Unlike urine testing — which detects drug metabolites blood testing measures the actual substance present in the bloodstream at the time of the test.

This makes blood drug testing especially useful for:
 

• Post-accident or on-the-job incidents

 

• Legal or court-ordered testing

 

• Reasonable suspicion cases

 

• Emergency screening

 

• Return-to-duty or follow-up evaluations

 

DOT Blood Drug Testing
For individuals in safety-sensitive positions regulated by the Department of Transportation (DOT), a blood drug test may be requested under specific circumstances, including:
 

• Post-accident investigations

 

• Reasonable suspicion of use

 

• Refusal or inability to produce a urine sample

All DOT-compliant blood tests at Top Tier Laboratory LLC follow strict chain-of-custody procedures, are processed by SAMHSA-certified laboratories, and reviewed by a Medical Review Officer (MRO) before final reporting.
 

Non-DOT Blood Drug Testing
Non-DOT blood testing is available for:
 

• Employers with zero-tolerance policies

 

• Legal/court compliance

 

• Healthcare professionals

 

• School systems or athletic programs

 

• Private or personal concerns

We offer 5-panel and 10-panel options, along with custom test panels based on your specific needs. Blood samples are processed promptly with confidential electronic results delivery.
