Hair testing is recognized as an effective means of detecting drug and alcohol consumption. The fibers of growing hair strands entrap biomarkers, providing a historical overview of alcohol and drug use. When hair is collected close to the scalp, it allows for a detection period of up to around 3 months for alcohol and other substances. The collection of hair is straightforward, challenging to tamper with, and easy to transport.
A sample of 1.5 inches, consisting of approximately 200 hair strands (similar in size to a #2 pencil) close to the scalp, will yield 100mg of hair, the perfect amount for initial screening and confirmation procedures. For EtG tests, additional panels, and/or tests involving more than 10 panels, it's advised to collect 150mg of the specimen. It's advisable to weigh the specimen with a jeweler’s scale. If head hair is unavailable, a comparable amount of body hair may be used. When the term head hair is used, it refers specifically to scalp hair, while body hair encompasses other types such as facial and axillary hair.
Process Overview
The laboratory processing of a drug test result encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial incorporation of a sample into laboratory records. The process includes checking that the sample was correctly sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and completing necessary data entry not covered by an electronic chain of custody system.
Screening conducts a quick preliminary test for drugs of abuse. Although Screening is an economical method to eliminate drug presence in most samples, any positive screen requires confirmation to be legally valid. Any samples showing presumptive positive results in Screening must undergo a secondary confirmation.
Should a sample yield a presumptive positive result in the Screening phase, more hair is obtained from the original specimen and prepared for Extraction. During Extraction, drugs are isolated from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug testing a challenging methodology to execute.
Positive screening results are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS methods. Necessary washing is performed on presumptive positive samples before confirmation. The entire laboratory procedure from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair guidelines and adheres to ISO / IEC 17025 accreditation standards.

Note: Despite often being called "hair follicle tests," these tests analyze the hair strand, not the follicle itself under the scalp.
