Hair analysis has emerged as a robust instrument for identifying alcohol and drug consumption. Hair offers a prolonged history by embedding biomarkers within the fibers of hair as it grows. When collected near the scalp, hair can provide up to a three-month detection window for alcohol and drugs. Hair collection is straightforward, hard to tamper with, and convenient to transport.
A 1.5-inch portion consisting of about 200 strands (like the size of a #2 pencil) nearest to the scalp weighs about 100mg, which is ideal for testing and verifying. For EtG, additional tests, or tests with more than 10 panels, 150mg is advisable. It is suggested to weigh the sample on a jeweler's scale. Should scalp hair be unavailable, a comparable quantity of body hair is acceptable. Head hair refers solely to scalp hair, whereas body hair includes all other hair types (facial, underarm, etc.).
Process Overview
The primary phases in processing a drug test in the lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into the lab system. This step includes verifying proper sealing and shipping, assigning a random Laboratory Accessioning Number (LAN), and completing any additional data entry absent from an electronic chain of custody system.
Screening serves as a preliminary check for drug presence. While cost-effective for ruling out drug use in most samples, a positive screen must be confirmed for court acceptance. Presumptive positives during Screening require subsequent confirmation.
With a presumptive positive result in the Screening phase, more hair is taken from the initial specimen for Extraction. Drugs are then extracted at a lower concentration than other methods (e.g., urine or oral fluid), making hair drug analysis more complex.
Confirmation of any positive Screening results is done using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed prior to confirmation if necessary. The entire lab procedure from Accessioning to Confirmation is overseen under both CAP (College of American Pathologists) Hair designation and accreditation per ISO/IEC 17025 standards.
