Hair examination is esteemed as an effective technique for identifying drug and alcohol usage. Hair provides a comprehensive history of substances by capturing biomarkers within the strands. When obtained near the scalp, hair can offer approximately a 3-month surveillance period for substances. Hair is easy to gather, somewhat challenging to tamper with, and straightforward to transport.
A 1.5-inch sample of roughly 200 hairs (around the size of a #2 pencil) nearest to the scalp constitutes 100mg of hair, which is optimal for analysis and validation. For EtG, add-ons, or tests exceeding 10 panels, a 150mg sample is advised. It's advisable to weigh the sample on a jeweler’s scale. If scalp hair is missing, an equivalent amount of body hair may be collected. When mentioning head hair, it specifically refers to scalp hair. Body hair indicates all other hair varieties (facial, axillary, etc.).
Process Overview
The principal steps in laboratory handling of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary processing of a sample into the laboratory's system. This involves verifying that the sample was correctly sealed and dispatched, designating a random LAN (Laboratory Accessioning Number), and completing any data entry not supplied by an electronic chain of custody system.
Screening is a swift inspection for drugs of misuse. While Screening is a cost-efficient method to dismiss drug usage in most samples, a positive screen must be confirmed for court acceptability. Any samples indicating presumptive positivity in Screening require a secondary confirmation.
If a specimen shows presumptive positivity during Screening, more hair is extracted from the initial sample and prepared for Extraction. Drugs in this phase are extracted from hair at a lower concentration compared to other methods (e.g., urine or oral fluid), which makes hair drug screening a complex methodology.
Confirmation of any positive screen is conducted through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleaned before confirmation when necessary. The entire laboratory procedure from Accessioning to Confirmation is overseen under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Note: While commonly termed "hair follicle tests", the analysis focuses on the hair strand, not the follicle beneath the scalp.
