Hair testing has emerged as an effective method for detecting drug and alcohol consumption. Hair retains a long-term record of intake by embedding biomarkers within the strands of the developing hair fiber. When collected near the scalp, it can reveal up to a 3-month period of drug and alcohol use. The collection process is straightforward, with minimal risk of tampering, and convenient to transport.
A 1.5-inch segment containing around 200 hair strands (about the thickness of a #2 pencil) closest to the scalp yields 100mg, the optimal quantity for evaluation and validation. For EtG, additional tests, or more than 10-panel assessments, 150mg of the specimen is suggested. We advise measuring the sample with a jeweler's scale. If scalp hair isn't available, an equivalent volume of body hair may be taken. Scalp hair specifically denotes hair from the head, while body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The drug testing laboratory procedure encompasses four essential steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial handling of a sample within a lab's workflow. This consists of confirming the proper seal and shipping of the sample, allocating a unique LAN (Laboratory Accessioning Number), and completing any further data entry not covered by an electronic chain of custody system.
Screening conducts an initial quick analysis for substances of abuse. Though Screening is a cost-efficient method to exclude drug use in most samples, a positive result requires confirmation to be valid for legal matters. Any samples with presumptive positivity in Screening necessitate additional verification.
If a sample shows presumptive positivity in Screening, additional hair is extracted from the initial sample and prepared for Extraction. At this stage, drugs are isolated from hair at a significantly lower concentration than in other techniques (e.g., urine or oral fluid), which is why hair drug testing is the most challenging methodology to execute.
Confirmation of any positive screening result is carried out via GC/MS, GC/MS/MS, or LC/MS/MS. All samples that test presumptive positive are thoroughly washed before confirmation as necessary. The complete laboratory workflow from Accessioning to Confirmation is evaluated per the CAP (College of American Pathologists) Hair classification and conforms to ISO / IEC 17025 standards.
