Hair analysis is recognized as an effective method for detecting substance use, both drugs and alcohol. Hair retains a record of alcohol and drug consumption over time by embedding biomarkers within its fibers. When gathered near the scalp, hair can reveal substance use within an estimated 3-month timeframe. Collecting hair is straightforward, tough to tamper with, and convenient for transport.
A sample measuring 1.5 inches, consisting of approximately 200 hair strands (equivalent to a #2 pencil's diameter), taken from the scalp, provides 100mg of hair—ideal for tests. For EtG, additional tests, or panels beyond 10, a 150mg sample is advised. We suggest using a jeweler’s scale to measure the specimen. Should scalp hair be unavailable, a similar quantity of body hair is an alternative. When we mention head hair, it pertains exclusively to scalp hair, whereas body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The drug testing process entails four key phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning denotes the preliminary processing of a sample into a lab’s system, covering the verification of proper sealing and shipping, assigning a Laboratory Accessioning Number (LAN), and filling in any missing data that an electronic custody system doesn’t provide.
Screening is a preliminary check for substance abuse. While cost-efficient for excluding drug use in most cases, a positive screen must be verified for legal acceptance. Samples indicating potential positivity in Screening necessitate an additional confirmation step.
In instances of presumptive positivity in Screening, additional hair is extracted from the initial sample for the Extraction phase. Here, drugs are extracted from hair at significantly lower concentrations than other techniques (e.g., urine, saliva), underscoring the complexity of performing hair drug screening.
A positive Screening outcome undergoes Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleansed before Confirmation as necessary. The complete laboratory procedure, from Accessioning to Confirmation, adheres to the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.

Limitations:
Note: Often termed "hair follicle tests," it is the hair shaft, not the scalp-embedded follicle, that’s analyzed.
