Hair analysis is now regarded as an effective approach for detecting drug and alcohol consumption. It offers a prolonged history of substance use by encapsulating biomarkers within the fibers of the hair as it grows. When obtained near the scalp, hair can indicate alcohol and drug use for roughly three months. Collecting hair is straightforward, challenging to tamper with, and easy to mail.
A hair sample of 1.5 inches, consisting of approximately 200 strands (resembling a #2 pencil), collected nearest to the scalp, yields 100mg of hair, which is optimal for both screening and confirmatory purposes. For tests involving EtG, additional panels, or tests beyond 10 panels, a 150mg sample is suggested. Using a jeweler’s scale for specimen weighing is advised. If scalp hair is not available, an equivalent amount of body hair can be substituted. When head hair is referenced, it specifically pertains to scalp hair. Body hair encompasses all other types (like facial, axillary, etc.).
Process Overview
The drug testing process in a laboratory encompasses Accessioning, Screening, Extraction, and Confirmation as the key phases.
During Accessioning, the sample undergoes initial systemization within the lab. This step ensures proper sealing and shipping, assigns a unique LAN (Laboratory Accessioning Number), and completes any necessary additional data input absent from an electronic chain of custody system.
Screening provides an initial assessment for drugs of abuse. While a cost-efficient method to dismiss drug presence in most samples, any positive results from Screening require confirmation for legal acceptance. Samples showing presumptive positives in Screening necessitate secondary confirmation.
In cases of presumptive positives in Screening, additional hair from the primary specimen is utilized for Extraction. At this stage, drugs are extracted at much lower concentrations from hair, compared to other methods (e.g., urine or saliva), making it the most complex methodology to execute.
GC/MS, GC/MS/MS, or LC/MS/MS techniques are used to confirm positive screening outcomes. Presumptive positive samples undergo washing before confirmation if needed. The entire testing procedure from Accessioning to Confirmation is reviewed under the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.
