Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. It captures long-term consumption patterns by embedding biomarkers within the fibers of growing hair. When obtained near the scalp, hair can reveal drug and alcohol use for up to three months. Hair is easy to collect, challenging to tamper with, and simple to transport.
A 1.5-inch segment of roughly 200 hair strands (about the width of a #2 pencil) closest to the scalp yields 100mg of hair, the ideal sample size for initial testing and confirmation. For Ethyl Glucuronide (EtG), supplementary tests, or panels beyond ten, 150mg of hair is advised. Utilizing a jeweler’s scale to measure the specimen is recommended. If scalp hair is not available, an equivalent amount of body hair can be used. References to head hair imply scalp hair only, while body hair includes other types (such as facial and armpit hair).
Process Overview
Four key stages make up the laboratory processing of a test result: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial step of integrating a sample into a lab’s system, ensuring proper sealing and shipment, assigning a Laboratory Accessioning Number (LAN), and completing any needed data entry not covered by an electronic chain of custody system.
Screening provides a preliminary check for drug presence. While it is an economical approach for ruling out drug use in most cases, a positive result must be verified to be legally credible. Any samples indicating a presumptive positive require a follow-up confirmation.
For presumptive positives identified in Screening, additional hair is taken from the initial sample for the Extraction process. This involves isolating drugs from hair at much lower concentrations than other methods (such as urine or saliva), making hair drug screening a challenging technique.
Positive screening results are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples are washed as necessary. The entire procedure from Accessioning to Confirmation is conducted under both the guidelines of the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
