The use of hair testing has emerged as an effective method for detecting drug and alcohol consumption. Hair traps biomarkers within the fibers of its growing strand, offering a comprehensive history of substances used, including alcohol, over an extended period. Gathering hair near the scalp provides a detection timeframe that can reach up to roughly three months for alcohol and other drugs. The collection of hair samples is straightforward, challenging to tamper with, and convenient to mail.
A sample measuring 1.5 inches, comprising around 200 hair strands (equivalent to the thickness of a #2 pencil) from the scalp area, will yield approximately 100mg—ideal for both screening and confirmation processes. For EtG tests, additional analyses, or tests exceeding ten panels, a sample size of 150mg is advisable. Utilizing a jeweler’s scale for weighing the hair sample is suggested. Should scalp hair be unavailable, collecting an equivalent volume of body hair is permissible. Head hair solely refers to scalp hair, whereas body hair encompasses all other types (such as facial, axillary, etc.).
Process Overview
The principal stages in the laboratory procedure for processing a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample is initially processed into a laboratory’s database. This step involves ensuring the sample's proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and executing any additional data entry absent from an electronic chain of custody system.
Screening is a preliminary assessment for drugs of abuse. Though Screening is an economical approach to eliminate drug usage in the majority of instances, a positive screen must be validated to qualify for legal proceedings. Any samples yielding a presumptive positive during Screening necessitate further confirmation.
In cases where a sample shows presumptive positivity at the Screening phase, additional hair is taken from the original sample for Extraction. Here, even a lower concentration of drugs is extracted from hair compared to other methods (like urine or oral fluid), underscoring the complexity of hair drug screening processes.
GC/MS, GC/MS/MS, or LC/MS/MS methods confirm any positive results from Screening. All samples identified as presumptively positive are cleansed before confirmation if necessary. The entire lab procedure, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair category and accreditation compliance with ISO / IEC 17025 standards.
