Hair examinations have emerged as an effective approach for the identification of alcohol and drug use. Hair captures a prolonged record of drugs and alcohol by encasing biomarkers within the strands of the growing hair. When taken near the scalp, hair can offer up to a 3-month detection period for drugs and alcohol. Hair collection is straightforward, relatively resistant to tampering, and easy to transport.
A sample size of 1.5 inches consisting of around 200 hairs (approximately the thickness of a #2 pencil) nearest to the scalp provides 100mg of hair, the optimal quantity for testing and verification. For tests exceeding 10 panels, EtG, or additional tests, a specimen weighing 150mg is advised. It is recommended to measure the sample with a jeweler’s scale. If there is no scalp hair, a similar quantity of body hair can be used. When mentioning head hair, it is specific to scalp hair. Body hair includes other types such as facial or axillary hair.
Process Overview
The laboratory processing of a drug test result is comprised of four main phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves entering a sample into a lab's system. This phase ensures the sample was correctly sealed and sent, assigns a unique LAN (Laboratory Accessioning Number), and records additional data not included in an electronic chain of custody.
Screening is a preliminary assessment for drugs of abuse. While a cost-efficient method for eliminating drug use in most samples, a positive result requires confirmation for legal acceptance. Samples identified as presumptively positive in Screening necessitate further confirmation.
If Screening suggests a sample is positive, additional hair is extracted from the initial specimen for Extraction. During this step, drugs are extracted from hair in much lower concentrations compared to methodologies like urine or oral fluids, making hair screening the most complex method to conduct.
GC/MS, GC/MS/MS, or LC/MS/MS methods are used for confirming any positive Screening result. Presumptive positive samples undergo washing before confirmation if necessary. The laboratory sequence from Accessioning to Confirmation is inspected under the CAP (College of American Pathologists) Hair designation along with ISO / IEC 17025 standards accreditation.

Note: Although often termed as "hair follicle tests", the test assesses the hair strand and not the follicle beneath the scalp.
