Hair analysis is increasingly recognized as an effective means for identifying drug and alcohol consumption. By capturing biomarkers within the fibers of hair as it grows, hair can provide an extended history of substance use. When taken from the area near the scalp, hair may reveal drug or alcohol presence for around a 90-day timeframe. Hair collection is straightforward, challenging to falsify, and convenient for transport.
A 1.5-inch segment consisting of roughly 200 hairs (approximating the width of a #2 pencil) taken nearest to the scalp equates to 100mg of hair, which is the ideal quantity for testing. For EtG additions or tests beyond 10 panels, 150mg of hair is advised. Utilizing a jeweler’s scale for weighing the sample is suggested. Should scalp hair be unavailable, an equivalent volume of body hair can be used. By head hair, we mean only scalp hair. Body hair includes all other hair types (facial, axillary, etc.).
Process Overview
The four primary phases in the laboratory processing to produce a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial sample processing into a lab’s framework. This step confirms the sample's proper sealing and shipment, assigns a unique LAN (Laboratory Accessioning Number), and handles any extra data entry absent from an electronic chain of custody system.
Screening provides an initial review for drugs of abuse. Screening is cost-efficient and useful for quickly excluding drug usage in most samples, but a positive screen necessitates confirmation to be court-admissible. Any samples that are presumptive positives in Screening require a subsequent confirmation.
When a sample indicates a presumptive positive during the Screening phase, additional hair is extracted from the original sample and set up for Extraction. During Extraction, drugs are extracted at a significantly lower concentration from hair as opposed to other methods (e.g., urine or oral fluid), making hair drug testing the most challenging methodology to execute.
Confirmation of any positive screening result is performed utilizing GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with presumptive positives undergo washing before confirmation when necessary. The entire lab sequence from Accessioning to Confirmation is audited under the CAP (College of American Pathologists) Hair designation and complies with ISO / IEC 17025 standards.
