Hair analysis is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair captures a protracted history of substances by embedding biomarkers within the fiber as it grows. Sampling hair near the scalp can offer a detection timeline of up to approximately 90 days for substances such as alcohol. Collecting hair is straightforward, challenging to tamper with, and convenient for transport.
A 1.5-inch hair segment, consisting of around 200 strands (similar in thickness to a #2 pencil) adjacent to the scalp, provides a 100mg sample, ideal for both initial screening and confirmatory processes. For EtG, additional panels, or exams exceeding 10 panels, 150mg of hair is preferred. It's advisable to measure the sample using a jeweler’s scale. If scalp hair isn’t available, body hair in an equivalent quantity may be used. Our reference to head hair is solely about scalp hair, whereas body hair encompasses other types (like facial or axillary).
Process Overview
The drug testing process in a laboratory is broken down into four main stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first step where a sample is integrated into the laboratory's system. This step involves ensuring the sample was sealed and transported correctly, generating a random LAN (Laboratory Accessioning Number), and completing any extra data entry tasks not covered by an electronic chain of custody system.
Screening conducts an initial assessment for substance misuse. Although Screening is an economical approach to exclude drug use in most samples, a positive result requires verification to be defensible in legal contexts. Any samples flagged as potentially positive in Screening must undergo further confirmation.
When a sample tests positive in the Screening phase, additional hair is extracted from the original sample for the Extraction step. This phase retrieves drugs from hair at notably low concentrations compared to other methods like urine or saliva testing, making hair drug screening particularly complex.
Positive results from Screening are confirmed through GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all samples with potential positives are cleaned as necessary. The entire procedure from Accessioning to Confirmation is evaluated according to both CAP (College of American Pathologists) Hair standards and ISO/IEC 17025 accreditation.
