Hair analysis is increasingly recognized as an effective method for identifying drug and alcohol consumption. It offers an extended timeline of substance use by embedding biomarkers in the hair's growing strands. When hair is sampled near the scalp, it can indicate substance use over a period of up to three months. Collecting hair is straightforward, it's relatively hard to tamper with, and transportation is uncomplicated.
A 1.5-inch section consisting of roughly 200 hair strands (approximately the thickness of a #2 pencil) from closest to the scalp yields 100mg of hair, which is the optimal sample mass for testing and validation. For EtG, additional tests, and/or more extensive screenings beyond 10 panels, a 150mg sample is advisable. We suggest verifying the specimen's mass using a jeweler’s scale. If scalp hair cannot be sourced, a comparable amount of body hair is acceptable. The term "head hair" exclusively pertains to scalp hair, while "body hair" encompasses all other hair varieties (facial, axillary, etc.).
Process Overview
The four primary phases in laboratory drug test processing are Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is initially processed into a laboratory's records. This includes checking the sample’s seal and shipping integrity, assigning a randomised LAN (Laboratory Accessioning Number), and completing any further data entry unavailable via an electronic chain of custody system.
Screening initiates a preliminary check for drugs of abuse. While Screening is an economical means of negating drug use in most samples, a positive screen must be verified to be court-admissible. Samples that are initially positive in Screening require a secondary verification.
If a Screening stage sample is initially positive, additional hair is extracted from the original specimen to prepare for Extraction. Here, the drugs are isolated from hair at a much lower concentration than other techniques (e.g., urine or oral fluid), which makes hair drug testing a rather challenging methodology to implement.
Verification of any positive Screening outcome is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are presumptive positives undergo washing before confirmation as necessary. The full laboratory protocol from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair standards and accreditation to ISO / IEC 17025 criteria.
