The analysis of hair has emerged as an effective method for uncovering drug and alcohol consumption. Hair contains a lengthy record of alcohol and drug intake by embedding biomarkers within the fibers of the developing hair strand. When taken close to the scalp, hair offers an approximate detection span of 3 months for alcohol and drugs. The process of collecting hair is straightforward, relatively resistant to tampering, and convenient for shipping.
A segment of 1.5 inches consisting of roughly 200 hair strands (approximately the width of a #2 pencil) nearest to the scalp provides 100mg of hair, which is the optimal amount for testing and confirmation. For EtG, supplements, and/or assessments beyond 10 panels, a 150mg specimen is advised. Utilizing a jeweler's scale to weigh the sample is suggested. If scalp hair is not accessible, a similar volume of body hair can be gathered. "Head hair" refers singularly to scalp hair. "Body hair" encompasses all other hair types, such as facial and axillary hair.
Process Overview
The laboratory's drug test analysis encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary integration of a sample into a lab's system. It involves ensuring the sample was correctly sealed and delivered, assigning a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data not provided by an electronic chain of custody mechanism.
Screening is a preliminary rapid examination to identify drugs. Though a cost-efficient method to generally rule out drug presence, a positive screen requires confirmation to be court-admissible. Any samples that show a presumptive positive in screening need further confirmation.
Should a sample exhibit a presumptive positive in the Screening phase, additional hair from the primary sample is used for Extraction. Here, drugs are extracted from hair at concentrations much lower than in other methods (e.g., urine or oral fluid), explaining the complexity of hair drug screening.
The validation of any positive screening outcomes is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo washing before confirmation if necessary. Throughout, the entire lab procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Note: Although commonly termed as "hair follicle tests", the examination involves the hair strand, not the follicle beneath the scalp.
