Hair analysis is increasingly recognized as an effective method for identifying substance and alcohol consumption. Hair captures a comprehensive historical record of alcohol and drug exposure by embedding indicators within the fiber of the hair shaft as it grows. When collected adjacent to the scalp, this method can offer a detection period of up to about 90 days for alcohol and other substances. Hair samples are easy to obtain, not easily tampered with, and simple to transport.
Taking a 1.5-inch hair sample of around 200 strands (comparable to the thickness of a #2 pencil) nearest to the scalp provides 100mg of hair, which is the optimal amount for both screening and verification. For EtG tests, add-ons, or tests beyond 10 panels, it is suggested to use 150mg of the sample. It is advisable to weigh the sample using a jeweler’s scale. If scalp hair cannot be used, a similar quantity of body hair is a suitable alternative. When mentioning head hair, it refers exclusively to scalp hair. Body hair includes all other types (like facial, axillary, etc.).
Process Overview
The four key stages in laboratory processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample is initially processed into the laboratory’s records. This step confirms that the sample was appropriately sealed and sent, assigns a unique LAN (Laboratory Accessioning Number), and completes any data entry not covered by an electronic chain of custody.
Screening involves a preliminary evaluation for drugs of abuse. Although Screening is a cost-efficient approach to exclude drug use in most samples, a positive screen must be verified for legal admissibility. Any samples that test presumptively positive in Screening require secondary verification.
If a sample tests presumptively positive during the Screening phase, additional hair is extracted from the original specimen for the Extraction process. In this phase, drugs are removed from the hair at a significantly reduced concentration than in other testing methods (such as urine or oral fluid), making hair drug testing the most complex methodology to execute.
Verification of any positive findings from the Screening is conducted through GC/MS, GC/MS/MS, or LC/MS/MS. All samples that show presumptive positive results are cleaned before confirmation as necessary. The complete laboratory process from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Note: Despite being often called "hair follicle tests", the examination itself focuses on analyzing the hair strand, not the follicle beneath the scalp.
