Hair testing is increasingly viewed as a robust method for identifying drug and alcohol consumption. Hair stores a long-term record of drug and alcohol intake by embedding biomarkers in its fibers as it grows. When clipped near the scalp, hair can provide a detection window of up to about three months for alcohol and other substances. Hair collection is straightforward, hard to tamper with, and can be easily transported.
A 1.5-inch section consisting of about 200 hair strands (approximately the thickness of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal amount for analysis and confirmation. For EtG, additional testing, and tests exceeding 10 panels, a specimen of 150mg is advised. Using a jeweler’s scale to weigh the specimen is suggested. If scalp hair is unavailable, a proportional amount of body hair may be used. References to head hair indicate scalp hair exclusively, while body hair encompasses all other types (such as facial or axillary hair).
Process Overview
The drug test result process in the lab consists of four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial setup of a sample within the laboratory's framework. This process ensures the sample was correctly sealed and shipped, assigns it a LAN (Laboratory Accessioning Number), and completes any additional information required but not supplied by an electronic custody chain.
During Screening, an initial, rapid test for drugs is administered. While Screening is a cost-efficient means to eliminate most drug usage concerns, any positive screen must be validated to be used in court. Samples that are initially positive during Screening need a secondary confirmation.
If a sample tests presumptively positive during the Screening phase, further hair is extracted from the original specimen for the Extraction phase. In this phase, drugs are removed from hair at lower concentrations compared to other methods (such as urine or oral fluid testing), making hair drug screening the most challenging methodology to execute.
Positive screening results are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. Any samples showing presumptive positivity are washed as necessary ahead of confirmation. The whole laboratory procedure from Accessioning through to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Limitations:
Note: While commonly named "hair follicle tests", the analysis is conducted on the hair strand and not the follicle situated beneath the scalp.
