Hair tests are recognized as an effective method for identifying drug and alcohol consumption. Hair captures biomarkers within the fibers of the growing hair strand, offering a comprehensive history of alcohol and other drugs. When collected near the scalp, hair can provide a detection period for alcohol and other drugs of up to approximately 3 months. Hair is easy to gather, challenging to tamper with, and simple to transport.
A sample of 1.5 inches, approximately 200 strands of hair (about the size of a #2 pencil) nearest to the scalp, will yield 100mg of hair, the optimal amount for screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, a 150mg specimen is advised. The specimen should be weighed using a jeweler’s scale. If scalp hair isn't available, an equivalent volume of body hair can be used. When discussing head hair, we specifically refer to scalp hair. Body hair includes all other types (facial, axillary, etc.).
Process Overview
The four primary steps in the lab processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the preliminary processing of a sample into a lab’s system. This includes ensuring the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry not supplied by an electronic chain of custody system.
Screening consists of an initial swift evaluation for drugs of abuse. While Screening offers a cost-effective way to dismiss drug usage in most samples, a positive screen must be validated to be admissible in court. Any samples that are preliminarily positive in Screening necessitate further confirmation.
If a sample tests as presumptively positive during the Screening step, additional hair is extracted from the initial specimen for preparation in Extraction. During this phase, drugs are retrieved from hair at a much lower concentration than other methods (such as urine or oral fluid), making hair drug screening the most complex methodology to conduct.
Confirmation of any positive screening result is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as required. The comprehensive lab procedure from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and adherence to ISO / IEC 17025 standards.

Note: While often termed "hair follicle tests", the test itself examines the hair strand, not the hair follicle under the scalp
