Hair analysis has become recognized as an effective method for detecting alcohol and drug consumption. Hair captures a detailed timeline of substances by embedding biomarkers within the strand’s follicles. When gathered near the scalp, hair can reveal a usage history spanning up to a 3-month period for alcohol and drugs. It is straightforward to collect, relatively challenging to tamper with, and convenient to transport.
Approximately 1.5 inches of hair comprising roughly 200 strands, akin to a #2 pencil's thickness, from near the scalp will yield about 100mg of hair, the optimal quantity for analysis and verification. For EtG, additional screenings, and/or tests exceeding 10 panels, a sample of 150mg is suggested. It's advisable to measure the sample using a jeweler’s scale. In the absence of scalp hair, an equivalent volume of body hair may be utilized. "Head hair" pertains solely to scalp hair. "Body hair" includes all other types (facial, axillary, etc.).
Process Overview
The essential phases in processing a drug test in the lab comprise Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the preliminary integration of a sample into a lab's database. Tasks here include verifying proper sample sealing and shipping, generating a unique LAN (Laboratory Accessioning Number), and executing any requisite data entry absent from an electronic custody framework.
Screening is a preliminary procedure to identify substances of abuse. Although Screening effectively excludes drug presence in most specimens, further validation is necessary for legal admissibility when a screen returns positive. Samples yielding a presumptive positive in Screening must undergo subsequent confirmation.
In cases of presumptive positivity during Screening, additional hair is extracted from the primary sample and processed for Extraction. This process retrieves drugs from hair at significantly reduced levels compared to alternate methods (e.g., urine or saliva), rendering hair drug testing particularly complex.
Confirming any positive results from Screening is achieved through GC/MS, GC/MS/MS or LC/MS/MS techniques. All samples with presumptive positivity undergo washing before confirmation as warranted. From Accessioning to Confirmation, all procedures are scrutinized under CAP (College of American Pathologists) Hair classification and comply with ISO / IEC 17025 accreditation standards.
