Employers, judicial bodies, and Substance Abuse counselors are choosing hair drug tests over urine tests. This testing option is favored by employers with zero-tolerance policies, courts, and probationary individuals due to its extended detection period of up to 90 days. While effective, urine tests remain most accurate for detecting drug use within the past 5 days.

Regarded as a potent method for uncovering substance and alcohol consumption, hair analysis reveals an extended timeline of drug and alcohol presence by preserving biomarkers within the fiber matrix of developing hair strands. Sampling hair close to the scalp offers a detection timeframe extending up to about three months for drugs and alcohol. Collecting hair is straightforward, challenging to tamper with, and convenient for transportation.
A segment of hair measuring 1.5 inches, approximately 200 strands (the thickness similar to a #2 pencil), nearest to the scalp provides 100mg of hair, an optimal amount for initial screening and confirmation tests. For additional assessments, especially EtG or tests exceeding 10 panels, 150mg is advised. Utilizing a jeweler’s scale for weighing the specimen is suggested. Should scalp hair be unavailable, an equivalent quantity of body hair is acceptable. Reference to head hair strictly indicates scalp hair, whereas body hair implies all other hair types (like facial, axillary, etc.).
Overview of the Process
The laboratory assessment of drug testing results incorporates four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the preliminary integration of a specimen into a laboratory's system. It consists of ensuring the sample's proper sealing and shipment, generating a random LAN (Laboratory Accessioning Number), and fulfilling any extra data entry omitted by an electronic chain of custody system.
Screening executes an initial rapid assessment for substances of misuse. Although Screening serves as an economical means to exclude drug usage in the majority of cases, any screen yielding positive results mandates confirmation for acceptance in legal contexts. Samples yielding tentative positive outcomes during Screening necessitate further validation.
Upon obtaining a tentative positive result during Screening, additional samples are retrieved from the initial batch and prepped for Extraction. This phase entails extracting drugs from hair at concentrations notably lower than alternative methodologies (such as urine or oral fluid), highlighting the complex nature of conducting hair drug screening.
Confirmation of any preliminary positive finding employs techniques like GC/MS, GC/MS/MS, or LC/MS/MS. Samples indicating potential positive results undergo washing before confirmation as required. The entire procedural flow from Accessioning to Confirmation adheres to review standards set by CAP (College of American Pathologists) Hair guidelines and complies with ISO / IEC 17025 accreditation benchmarks.
