Hair analysis is recognized as an effective means for detecting the intake of drugs and alcohol. Hair retains lasting evidence of these substances by embedding biomarkers within the fibers of the growing hair strand. With samples taken near the scalp, it can show a detection window of up to around 3 months for various substances. Hair collection is straightforward, hard to tamper with, and easy to transport.
A 1.5-inch snippet of roughly 200 hair strands (similar to the girth of a #2 pencil) nearest the scalp provides 100mg of hair, which is the preferred sample for assessments and confirmations. For EtG, extended tests, or panels exceeding 10, 150mg of hair is advisable. Using a jeweler’s scale to weigh the hair is suggested. In instances where scalp hair is unavailable, a comparable quantity of body hair may be utilized. By head hair, we mean scalp hair specifically. Body hair encompasses other hair forms (facial, axillary, etc.).
Process Overview
The drug testing result process in the lab includes four primary steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is initially processed into the lab’s system. This phase involves confirming the sample's sealed condition and correct shipping, generating a random LAN (Laboratory Accessioning Number), and fulfilling further data entry tasks absent in an electronic chain of custody system.
In Screening, a preliminary assessment for drug abuse is performed. Although Screening is a cost-efficient method to exclude drug consumption for the majority, any positive screen results must be verified to hold up in legal proceedings. Presumptive positive samples in Screening necessitate further confirmation.
Should a sample show a presumptive positive outcome during Screening, additional hair is extracted from the original sample and prepped for Extraction. Here, drugs are drawn from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), illustrating the challenging nature of hair testing methodology.
Positive screening results are confirmed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation if needed. The entire lab procedure from Accessioning to Confirmation is subject to oversight under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.

Note: Even though widely termed as "hair follicle tests", the assessment targets the hair strands and not the follicles beneath the scalp.
