Hair assessments have gained recognition as an effective means of identifying drug and alcohol consumption. Hair retains a prolonged record of alcohol and drug exposure by capturing biomarkers within the strands in growth. When taken from near the scalp, hair can reveal drug and alcohol use for around a three-month period. The process of hair collection is straightforward, challenging to tamper with, and simple to transport.
A sample of 1.5 inches, comprising approximately 200 hair strands (comparable in size to a #2 pencil) from closest to the scalp, provides 100mg of hair, which is perfect for analysis and confirmation. For EtG, specific add-ons, or tests exceeding 10 panels, a 150mg sample is preferred. Measuring the sample on a jeweler’s scale is advised. If scalp hair is unavailable, a comparable amount of body hair is acceptable. References to head hair indicate exclusively scalp hair, whereas body hair signifies all other types (e.g., facial, axillary).
Process Overview
The laboratory processing of drug test outcomes involves four major steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the introductory processing of a sample into a laboratory’s system, including the confirmation of proper sealing and shipping, the assignment of a unique LAN (Laboratory Accessioning Number), and the completion of any supplemental data input omitted by an electronic chain of custody system.
Screening pertains to an initial and rapid assessment for drug misuse. Though Screening is an economical approach to exclude drug use in most cases, a positive finding necessitates confirmation for legal acceptability. All samples flagged as presumptively positive during Screening require secondary validation.
When a sample turns presumptively positive in Screening, additional hair is extracted from the initial sample and readied for Extraction. This phase involves extracting drugs from hair at considerably lower concentrations than other methods (e.g., urine or oral fluid), highlighting why hair drug analysis is exceptionally challenging.
The Confirmation of any positive screening result is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Each presumptively positive sample undergoes cleaning before confirmation, as needed. The entire lab procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.

Note: While commonly labeled as "hair follicle tests", the examination targets the hair strand, not the follicle beneath the scalp.
