Hair analysis is increasingly recognized as an effective method for identifying drug and alcohol consumption. By capturing biomarkers in the fibers of the hair as it grows, hair provides a comprehensive history of substance use over an extended period. When the hair is sampled from near the scalp, it can offer a detection timeframe of up to around 3 months for alcohol and drugs. Hair is easy to gather, challenging to tamper with, and straightforward to transport.
Taking a sample of approximately 1.5 inches—equivalent to about 200 strands of hair (roughly the diameter of a #2 pencil)—nearest to the scalp will yield 100mg, which is optimal for screening and confirmation. In the case of EtG, additional tests, or when requiring more than 10 panels, a specimen weight of 150mg is suggested. Using a jeweler's scale to weigh the specimen is advised. If scalp hair is not available, a corresponding amount of body hair may be used. References to head hair pertain solely to scalp hair. Body hair includes all other types of hair (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test involves four critical stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of the sample's initial integration into the lab's system. This step includes ensuring the sample's proper sealing and shipment, assigning a unique LAN (Laboratory Accessioning Number), and completing any extra data entry absent from an electronic chain of custody system.
Screening is a preliminary rapid assessment for drugs of abuse. While cost-effective for excluding drug use in most samples, a positive screen must be verified to be legally valid. Any samples with a presumptive positive result in Screening require further confirmation.
Should a sample return a presumptive positive during the Screening phase, additional hair is drawn from the initial sample for Extraction. Drugs are extracted from hair in much lower concentrations compared to other methods (e.g., urine or oral fluid), which contributes to the complexity of hair drug screening.
Confirmation of any positive screening outcome is performed using techniques like GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples undergo washing if necessary. The complete lab procedure, from Accessioning to Confirmation, is assessed according to both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.
