Hair testing is increasingly recognized as a potent method for identifying drug and alcohol consumption. It provides a comprehensive timeline of substance use by embedding biomarkers within the strands of hair as it grows. When taken from near the scalp, hair samples offer a detection timeframe of up to roughly three months for both alcohol and drugs. Hair samples are simple to gather, hard to tamper with, and straightforward to transport.
A segment of hair measuring 1.5 inches, consisting of roughly 200 strands (akin to the width of a #2 pencil), closest to the scalp yields about 100mg of hair, the optimal quantity for screening and confirmation processes. For EtG, additional tests, and/or screenings beyond 10-panel tests, a sample of 150mg is suggested. It is advisable to weigh the hair sample using a jeweler’s scale. If scalp hair is not accessible, an equivalent quantity of body hair can be utilized. References to head hair specifically mean scalp hair, whereas body hair includes all other types such as facial and axillary hair.
Process Overview
The fundamental stages in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial incorporation of a specimen into a lab’s database, verifying proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any supplemental data entry absent from an electronic chain of custody system.
Screening presents a preliminary, swift examination for drug presence. While cost-effective for excluding drug use in most samples, a positive screen needs confirmation for legal acceptance. Samples with a presumptively positive result in Screening require an additional confirmation.
For presumptively positive samples identified during Screening, added hair from the initial sample is prepared for Extraction, involving drug removal from hair at significantly lower concentrations than in other approaches (e.g., urine or oral fluid), making hair screening the most challenging technique.
Confirmation of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples are cleansed as necessary before confirmation. The entire laboratory process from Accessioning through Confirmation is evaluated following both the CAP (College of American Pathologists) Hair criteria and is accredited to ISO / IEC 17025 standards.
