Urine Drug Testing Services

NMS Screening & Compliance provides professionally administered urine drug testing services designed to support workplace safety, regulatory compliance, and defensible employment decisions.

Urine Drug Testing Overview

Urine drug testing detects the presence of drug metabolites, which are substances the body produces after a drug has been processed. Because metabolites may remain in the body after the drug’s immediate effects have worn off, urine testing is used to identify prior drug use, not current impairment.

Urine testing is commonly used in:

• Pre-employment screening.
• Random drug testing programs.
• Post-accident testing.
• Reasonable suspicion testing.
• Return-to-duty and follow-up testing.

Substances Commonly Detected

Standard urine drug testing panels may screen for substances such as:

• Marijuana (THC metabolites).
• Cocaine.
• Amphetamines.
• Methamphetamines.
• Opiates (including heroin, morphine, codeine).
• Phencyclidine (PCP).

Additional drugs may be included depending on the testing panel and employer requirements.

Detection Window Considerations

Urine drug testing provides a window of detection that varies based on:

• The substance used.
• Frequency and quantity of use.
• Individual metabolism.

In general, urine testing identifies recent drug use, rather than real-time impairment. A positive result indicates prior exposure to a substance but does not determine when use occurred or whether an individual was impaired at the time of testing.

Regulatory Acceptance and Legal Defensibility

Urine drug testing has long been the primary testing method used in federally regulated programs, including those governed by the U.S. Department of Transportation (DOT). While additional specimen types are now permitted under certain regulations, urine testing remains the most widely implemented and recognized method due to its established procedures and extensive regulatory history.

For regulated and non-regulated employers, laboratory-based urine testing provides confirmed, legally defensible results when performed in accordance with federal guidelines.

Laboratory Partnerships and Collection Standards

NMS Screening & Compliance works with SAMHSA-certified laboratories, including some of the largest and most respected laboratories in the United States. Urine specimen collections are conducted using standardized procedures designed to protect specimen integrity, maintain the chain of custody, and support reliable results.
