The utilization of hair analysis is now acknowledged as an effective means to identify alcohol and drug consumption. Hair retains a prolonged history of substance use by capturing biomarkers within the fibers of the hair as it grows. When taken near the scalp, hair can offer around a 3-month detection period for alcohol and substances. It's effortless to gather, relatively challenging to tamper with, and simple to transport.
A 1.5-inch section, approximately the thickness of a #2 pencil, consisting of about 200 hair strands near the scalp, will yield 100mg, which is the optimal sample size for testing and validation. For EtG, additional tests, and/or assessments exceeding 10 panels, 150mg is suggested. Using a jeweler's scale for weighing the sample is advisable. If scalp hair isn't obtainable, a comparable quantity of body hair can be used. When we speak of head hair, it refers solely to scalp hair. Body hair comprises all other types including facial and axillary hair.
Process Overview
The process of laboratory testing for drug-related outcomes entails four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning begins with the initial intake of a sample into a laboratory’s system. This encompasses ensuring the sample was sealed and transported accurately, generating a random LAN (Laboratory Accessioning Number), and finalizing any data input not included by an electronic chain of custody system.
Screening involves a preliminary rapid assessment for drug abuse substances. Although Screening is a cost-effective strategy to dismiss drug presence in most samples, a positive finding from screening mandates confirmation to be legally valid. Any samples with a presumptive positive result in Screening necessitate an additional confirmation step.
Should a specimen show a presumptive positive outcome during Screening, further hair is taken from the initial sample and prepped for the Extraction phase. At this juncture, drugs are isolated from hair at a substantially lower concentration than other techniques like urine or oral fluid testing, making hair analysis the most challenging to execute.
Confirmation of any positive screening outcome is carried out using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with presumptive positive findings are cleansed prior to confirmation if required. The full laboratory process, from Accessioning all the way through Confirmation, undergoes review under the CAP (College of American Pathologists) Hair designation and adheres to ISO/IEC 17025 accreditation.

Limitations:
Note: Despite being colloquially known as "hair follicle tests", the analysis targets the hair strand rather than the follicle situated beneath the scalp.
