The use of hair testing has emerged as a significant method for detecting substance use. Hair serves as a long-standing record of substance intake by embedding biomarkers within the strands during hair growth. When taken close to the scalp, it can reveal substance use over about a 90-day period. Hair collection is straightforward, challenging to tamper with, and simple to transport.
A sample measuring 1.5 inches, consisting of roughly 200 hair strands (around the thickness of a #2 pencil) from near the scalp, will yield 100mg of hair, considered the optimal quantity for analysis and verification. For EtG, additional tests, and analyses exceeding 10 panels, a specimen of 150mg is advised. It is suggested to weigh the specimen using a jeweler’s scale. If head hair is not available, the same quantity of body hair can be collected. Reference to head hair implies scalp hair exclusively. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The key steps in the lab processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial integration of a sample into a laboratory’s system. This process involves checking the integrity of the sample's seal and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any missing information not supplied by an electronic chain of custody system.
Screening provides a quick preliminary check for substances of abuse. Although Screening is an economical measure for negating substance use in most cases, any positive screen needs confirmation for legal proceedings. Samples testing presumptively positive during Screening require further validation.
If a sample tests presumptively positive at the Screening phase, additional hair from the initial batch is utilized for Extraction. Here, substances are extracted at lower concentrations compared to other methods (such as urine or oral fluid tests), which is why hair drug screening is considered complex.
The Confirmation phase for any positive Screening result is carried out using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumed positive samples undergo washing before confirmation as needed. The complete process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair criteria and accreditation to ISO / IEC 17025 standards.
