Hair testing has become recognized as an effective method for detecting drug and alcohol consumption. Hair strands store a long-term record of such use by capturing biomarkers within the fibers of the hair as it grows. When the sample is gathered near the scalp, it can offer up to around a 3-month period of detection for the presence of alcohol and drugs. The process of collecting hair is straightforward, relatively resistant to tampering, and simple to transport.
A sample of 1.5 inches, comprising roughly 200 hair strands (similar to the thickness of a #2 pencil) taken nearest to the scalp, yields 100mg of hair, which is optimal for both screening and confirmation. For EtG tests, additional screenings, and tests exceeding 10 panels, a specimen of 150mg is advisable. It is suggested to measure the hair on a jeweler’s scale. In situations where scalp hair cannot be acquired, an equivalent amount of body hair may be utilized. By 'head hair', we specifically mean scalp hair; 'body hair' refers to all other types (such as facial or axillary hair).
Process Overview
The primary steps in the laboratory analysis of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial sample handling within the lab's system. This step ensures the sample was properly sealed and sent, assigns a random LAN (Laboratory Accessioning Number), and completes any necessary data entry not covered by an electronic chain of custody system.
Screening is the initial rapid assessment for drug presence. While it is an economical approach to exclude drug use in most samples, a positive screen must be substantiated to hold up in legal contexts. Samples testing positive in Screening require secondary confirmation.
If a sample indicates a positive result in the Screening phase, additional hair from the initial sample is prepared for Extraction. During this phase, drugs are pulled from hair at a much lower concentration compared to other methods (like urine or oral fluid), making hair drug testing one of the most challenging methods to conduct.
Confirmation of positive screening results is carried out using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with preliminary positive results undergo washing before confirmation as necessary. The comprehensive lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and adherence to ISO / IEC 17025 standards.
Advantages of hair drug testing:

Note: Commonly termed as "hair follicle tests", the testing actually involves the hair strand and not the scalp-embedded follicle.
