The use of hair follicle drug tests has grown significantly in recent years. Many businesses, judicial systems, and Substance Abuse counselors are turning to hair testing instead of conventional urine samples. Employers with strict no-drug use policies, courts, and probation services prefer hair follicle tests. The significant advantage lies in its detection period, extending up to 90 days, with a witnessed collection process, making it nearly tamper-proof. However, for identifying drug use within the previous 5 days, the urine test remains the best choice.

Hair testing has gained recognition as an effective mechanism for identifying drug and alcohol consumption. This method captures a comprehensive timeline of alcohol and other drugs by embedding biomarkers in the fibers of the hair shaft as it grows. When obtained near the scalp, hair samples can offer a detection range of up to about 3 months for substances like alcohol and drugs. Collecting hair is straightforward, relatively tamper-proof, and easy to transport.
A 1.5-inch segment comprising roughly 200 hair strands (approximately the diameter of a #2 pencil) closest to the scalp yields 100mg, which is considered the optimal quantity for testing and confirmation. For EtG, add-on tests, and/or panels exceeding 10, a 150mg sample is preferable. Using a jeweler’s scale, we suggest validating the specimen's weight. If head hair is inaccessible, an equivalent volume of body hair can be used. "Head hair" specifically pertains to scalp hair, while "body hair" encompasses all other variants (such as facial and axillary hair).
Process Overview
The drug test outcome in the lab is processed through four key phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial stage where a sample enters a lab's system. This step includes confirming that the sample was adequately sealed and sent, allocating a unique LAN (Laboratory Accessioning Number), and performing any extra data input absent from an electronic chain of custody framework.
Screening serves as an initial, rapid evaluation for drug presence. Although Screening is a cost-effective method to dismiss drug usage in most cases, any positive findings require confirmation for legal admissibility. Samples that are initially deemed positive in Screening necessitate further validation.
In instances where Screening indicates a presumptive positive, extra hair is extracted from the original specimen for Extraction preparation. At this phase, drugs are isolated from hair at much lower concentrations than other methods (e.g., urine or oral fluid), explaining the complexity of hair drug screenings.
To confirm any positive Screenings, methods such as GC/MS, GC/MS/MS, or LC/MS/MS are used. Presumptive positive samples are cleansed before verification as needed. The entire lab procedure, from Accessioning to Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.
