Hair analysis has gained recognition as an effective means for identifying drug and alcohol consumption. Hair captures a prolonged history of alcohol and drug use by locking in biomarkers within the strands as they grow. When gathered from the scalp area, hair can present up to nearly a three-month detection timeline for alcohol and drugs. Collecting hair is straightforward, relatively tamper-proof, and convenient to transport.
A 1.5-inch section composed of roughly 200 strands of hair (comparable in size to a #2 pencil) closest to the scalp will yield 100mg of hair, the optimal amount for screening and confirming. For EtG, additional tests, and/or panels exceeding 10, it is suggested to use 150mg of hair. It is advisable to measure the hair on a jeweler’s scale. Should scalp hair be unavailable, a similar quantity of body hair can be used. When mentioning head hair, it refers exclusively to scalp hair. Body hair encompasses all other types (such as facial and axillary hair).
Process Overview
The laboratory analysis of a drug test result consists of four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into a lab’s processes. This step verifies that the sample was sealed and dispatched correctly, allocates a random LAN (Laboratory Accessioning Number), and completes any extra data entry missing from an electronic chain of custody system.
Screening provides a preliminary assessment for drugs of abuse. Though Screening presents a cost-efficient method to dismiss drug use in most samples, a positive result in screening must be validated to hold in a legal setting. Samples that test positive during Screening require further confirmation.
If the Screening phase renders a presumptive positive result, additional hair is extracted from the original sample and readied for Extraction. In this phase, drugs are isolated from the hair at concentrations significantly lower than those in other testing methods (such as urine or oral fluid); hence, hair drug testing presents a heightened challenge.
The Confirmation of any positive Screening outcome employs techniques like GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples undergo washing as needed. The entire lab workflow, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair criteria and the accreditation under ISO / IEC 17025 standards.

Note: Though colloquially termed as “hair follicle testsâ€, the analysis focuses on the hair strand itself and does not examine the follicle beneath the scalp.
