Today, hair analysis is recognized as a potent method for identifying drug and alcohol consumption. Hair strands capture biomarkers in their fibers, offering an extended record of substance use. Collected near the scalp, it can reveal drug and alcohol use from as far back as three months. Hair collection is straightforward, challenging to tamper with, and convenient for mailing.
Gathering a 1.5-inch section of roughly 200 hair strands (approximately the width of a #2 pencil) closest to the scalp yields 100mg, the ideal amount for screening and validation. For EtG, add-ons, or over 10-panel tests, 150mg is advised. It's preferable to use a jeweler’s scale for weighing. If scalp hair is absent, an equivalent quantity of body hair is acceptable. "Head hair" specifically refers to hair from the scalp, whereas "body hair" includes all other types (e.g., facial, axillary).
Process Overview
The laboratory stages for processing a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample is initially integrated into the laboratory system. This process ensures the sample was appropriately sealed and transported, assigns a unique LAN (Laboratory Accessioning Number), and completes any missing information not provided by a digital chain of custody service.
Screening provides an initial evaluation for drug presence. While this method is budget-friendly for eliminating negative samples, a positive result must be confirmed for legal admissibility. Any samples with an initial positive result from Screening need further confirmation.
If Screening suggests a positive result, additional hair from the sample is utilized for Extraction. Drugs in hair are extracted at significantly lower concentrations compared to other methods (e.g., urine or saliva), making hair drug detection the most challenging to conduct.
Positive Screening outcomes undergo Confirmation using techniques like GC/MS, GC/MS/MS, or LC/MS/MS. Necessary washing of any positive samples is performed before confirmation. Every step from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair criteria and ISO/IEC 17025 accreditation standards.
