Hair testing is now recognized as a potent method for identifying drug and alcohol consumption. Hair offers an extended timeline of substance use by capturing biomarkers within its developing strands. When taken near the scalp, hair can reveal drug and alcohol use for up to about three months. Collecting hair is straightforward, difficult to tamper with, and simple to transport.
A 1.5-inch section of approximately 200 hair strands (similar to a #2 pencil's width) nearest to the scalp provides 100mg, which is the optimal amount for tests. For EtG, additional analyses, and/or panels exceeding ten, 150mg of hair is advised. We suggest using a jeweler’s scale for precision. If scalp hair isn't accessible, a similar quantity of body hair can be used. By "head hair," we mean only scalp hair. "Body hair" encompasses all other hair forms (beard, underarm, etc.).
Process Overview
The laboratory drug test procedure comprises four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary step of integrating a sample into a lab's system. This step includes confirming proper sealing and shipping, assigning a LAN (Laboratory Accessioning Number), and completing any missing data entry not provided by an electronic chain of custody.
Screening performs an initial assessment for drug traces. While cost-efficient to eliminate drug use in most instances, a positive result in Screening must be confirmed for legal admission. Any samples testing positive at this stage require further verification.
If a sample tests positive during Screening, additional hair from the initial batch is readied for Extraction. Here, drugs are isolated from hair at lower concentrations than those in other testing methods (e.g., urine or saliva), which makes hair drug testing the most challenging methodology.
Confirmation of any positive screening results is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Before Confirmation, all presumptive positives undergo a wash as necessary. Every step from Accessioning to Confirmation is vetted under both the CAP (College of American Pathologists) Hair guidelines and accreditation to ISO / IEC 17025 standards.

Limitations:
Note: Commonly dubbed "hair follicle tests", these tests actually examine the hair strand, not the follicle beneath the scalp.
