Recently, drug testing methods have increasingly included hair follicle analysis. Numerous employers and judicial bodies now prefer hair testing over urine testing. Hair follicle tests are utilized by organizations enforcing zero-tolerance policies, legal entities, and probation cases. A key advantage is a longer detection timeframe, up to 90 days, collected securely and resistant to tampering, while urine tests remain best for recent drug use detection within 5 days.

Recognized as a strong instrument, hair testing is used to spot drug and alcohol consumption. Hair captures biomarkers in its fibers, offering a prolonged record of substance use. When taken near the scalp, it can indicate drug and alcohol use for up to about three months. Hair collection is straightforward, challenging to alter, and can be shipped without difficulty.
A 1.5-inch sample of roughly 200 hair strands (comparable to the size of a #2 pencil) closest to the scalp offers 100mg of hair, which is perfect for testing. For EtG, enhancements, and/or tests above 10 panels, 150mg of hair is advised. Using a jeweler's scale is suggested for specimen weighing. If head hair can't be obtained, an equivalent body hair sample may be used. By "head hair," we mean scalp hair, while "body hair" includes all other types (facial, axillary, etc.).
Process Overview
Laboratory processing of a drug test result involves four chief steps: Accessioning, Screening, Extraction, and Confirmation.
In Accessioning, a sample is initially integrated into the lab’s system. This step ensures proper sealing and shipping of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes any extra data entry absent in an electronic chain of custody setup.
Screening offers a preliminary rapid test for drug abuse. As a cost-efficient method to exclude drug use in most samples, any positive results from Screening must be confirmed to be legally defensible. Samples that show a positive indication in Screening require follow-up confirmation.
For samples presumed positive during Screening, additional hair is extracted from the initial sample to prepare for Extraction. At this stage, drugs are retrieved from hair in concentrations lower than other methods (e.g., urine or oral fluid), making hair drug screening the toughest to execute.
Confirmation of positive screenings is done using GC/MS, GC/MS/MS or LC/MS/MS. Presumptive positive samples undergo washing prior to confirmation as needed. Every step from Accessioning to Confirmation is reviewed under the CAP (College of American Pathologists) Hair designation with ISO / IEC 17025 accreditation.
