Recently, hair follicle drug testing has increasingly become a favored method for drug screening. Employers, courts, and substance abuse professionals often opt for a hair drug test over the traditional urine test. Organizations and entities with stringent zero-tolerance policies, as well as those monitoring probation, rely heavily on hair follicle tests. Their main advantage lies in the extended detection period, covering up to 90 days and being nearly impossible to manipulate, provided the test is conducted under supervision. However, urine tests remain more reliable for detecting very recent drug use, specifically within the past 5 days.

Hair testing has emerged as a robust method for identifying drug and alcohol consumption. Hair offers an extended record of alcohol and drug use by embedding biomarkers within the strands as they grow. If obtained near the scalp, hair provides a detection period of up to roughly three months for alcohol and drugs. Hair collection is straightforward, relatively tamper-resistant, and easy to transport.
A 1.5-inch segment of roughly 200 hair strands (comparable to the diameter of a #2 pencil) closest to the scalp yields 100mg of hair, which is the preferred sample size for both screening and confirmation. For EtG, additional tests, and those exceeding 10 panels, a 150mg sample is suggested. It is advised to weigh the sample using a jeweler’s scale. If head hair is unavailable, a similar mass from body hair can be collected. When mentioning head hair, it refers exclusively to scalp hair. Body hair encompasses all other types, such as facial and axillary.
Process Overview
The laboratory analysis of a drug test result comprises four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into a lab's system, which involves checking that the sample was properly sealed and dispatched, assigning a Laboratory Accessioning Number (LAN), and finalizing any additional data entry not covered by an electronic chain of custody system.
Screening is an initial rapid assessment for drug substances. While it's a cost-efficient way to exclude drug usage for most samples, a positive screen must be verified to be court-admissible. Presumed positive samples from Screening require further confirmation.
If Screening results are presumptively positive, additional hair is taken from the initial sample for Extraction. At this phase, drugs are extracted from hair at much lower concentrations than other methods (e.g., urine or oral fluid), making hair drug testing the most challenging to execute.
Confirmation of a positive result is carried out using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positives are cleansed before confirmation as needed. The entire lab process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair category and ISO / IEC 17025 accreditation standards.
