Hair analysis is recognized as an effective method for identifying drug and alcohol consumption. Hair serves as a long-term record of alcohol and drug usage by encapsulating biomarkers within its growing strands. When collected proximal to the scalp, hair can yield a detection timeframe of up to about three months for alcohol and drugs. Hair sample collection is straightforward, relatively resistant to tampering, and convenient for shipping.
A 1.5-inch segment comprising roughly 200 hair strands (comparable to the size of a #2 pencil) situated nearest to the scalp will result in 100mg of hair, which is the optimal sample for screening and confirmation purposes. For EtG, additional panels, and/or tests exceeding 10 panels, a recommendation of 150mg for the specimen is suggested. We advise using a jeweler’s scale for precise measurement of the specimen. In cases where scalp hair is unattainable, a comparable quantity of body hair can be used. References to head hair denote only scalp hair, while body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The four key phases in laboratory analysis of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial integration of a sample into a laboratory's workflow. This process encompasses the verification that the sample was appropriately sealed and dispatched, the allocation of a randomized LAN (Laboratory Accessioning Number), and the conclusion of any incomplete data entry absent from an electronic chain of custody system.
Screening constitutes a preliminary rapid assessment for substance abuse. While Screening is a cost-efficient technique to dismiss drug usage for the majority of samples, a positive screen needs verification to be permissible in legal proceedings. Any samples presenting presumptive positivity during Screening necessitate secondary confirmation.
If a sample emerges as presumptive positive in the Screening phase, additional hair is extracted from the original specimen and readied for Extraction. During this stage, drug extraction from hair occurs at a notably lower concentration compared to other methodologies (e.g., urine or oral fluid), which accounts for the complexity of hair drug screening.
Confirmation of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples identified as presumptive positive undergo washing before confirmation as required. The entire laboratory procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Note: Although often termed as "hair follicle tests", the examination focuses on the hair strand rather than the follicle beneath the scalp.
