Hair analysis has emerged as an effective means for identifying drug and alcohol consumption. Hair captures a historical record of substances by embedding biomarkers within the hair shaft as it grows. When sourced closely from the scalp, hair offers an up to 3-month detection range for both alcohol and other drugs. The collection of hair samples is straightforward, relatively tamper-resistant, and convenient to transport.
A sample of 1.5 inches, approximately 200 hair strands (akin to a #2 pencil in volume), near the scalp, results in 100mg of hair, the optimal quantity for both screening and validation. For EtG, add-ons, or tests beyond 10 panels, a specimen of 150mg is advised. A jeweler’s scale can be used to ensure accurate specimen weight. If head hair is not available, an equivalent portion of body hair is acceptable. The term head hair refers exclusively to scalp hair. Body hair encompasses all other varieties (facial, axillary, etc.).
Process Overview
The primary four phases in laboratory processing of a drug testing result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial sample integration into a laboratory's framework, which involves checking the seal and shipment of the sample, assigning a unique LAN (Laboratory Accessioning Number), and completing any remaining data input absent from an electronic chain of custody system.
Screening is a preliminary evaluation for abusive substances. Although Screening is an economical method to determine drug usage in most samples, a positive screen necessitates confirmation to be legally valid. Samples indicating a presumptive positive in Screening must undergo further confirmation.
For samples showing a presumptive positive during Screening, additional hair is extracted for the Extraction stage. At this phase, drugs are isolated from hair at concentrations lower than those in other methods (e.g., urine or oral fluid), illustrating the complexity of hair drug screening.
Confirmation of any positive screening outcome is executed through GC/MS, GC/MS/MS, or LC/MS/MS. Samples with presumptive positives undergo washing prior to confirmation as necessary. The complete laboratory procedure from Accessioning to Confirmation is audited following both the CAP (College of American Pathologists) Hair category and the ISO / IEC 17025 accreditations.

Limitations:
Note: Despite being termed "hair follicle tests," the procedure actually analyzes the hair shaft, not the follicle beneath the scalp
