The preference for hair follicle drug testing over other methods has grown significantly in recent years. Employers, legal systems, and addiction specialists often select hair tests instead of traditional urine tests. Hair follicle testing is integral for organizations enforcing zero-tolerance policies on drug use and is also popular with judicial systems and probation services. The standout benefit of this testing method is its extensive detection window, typically up to 90 days. Hair tests are administered under observed conditions and are difficult to manipulate. However, urine tests remain the most precise for detecting recent usage within a 5-day period.

Hair testing is increasingly recognized as an effective method for detecting drug and alcohol consumption. Hair retains a long-term history of substance use due to biomarkers being embedded within the hair shaft. When hair is collected near the scalp, it provides a detection period of up to three months for alcohol and other substances. Hair sampling is straightforward, relatively tamper-proof, and easy to transport.
A 1.5-inch sample of approximately 200 hair strands, comparable in size to a #2 pencil, is sufficient for the ideal 100mg sample needed for testing and confirmation. For EtG, additional testing, or panels exceeding 10, a 150mg sample is advisable. We suggest using a jeweler's scale to measure the sample. If scalp hair is not available, a similar amount of body hair can be used instead. "Head hair" specifically refers to scalp hair, whereas "body hair" encompasses all other types (such as facial or underarm hair).
Process Overview
The drug testing laboratory process comprises four pivotal stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is introduced into the lab's system. This phase involves checking that the sample was securely sealed and properly sent, assigning it a unique LAN (Laboratory Accessioning Number), and entering any other necessary data absent from an electronic chain of custody system.
Screening is a preliminary evaluation for the presence of substances. Though cost-effective, a positive result from Screening must be confirmed to be valid in legal settings. Hence, any sample indicating a potential positive must undergo further Confirmation.
If the Screening phase suggests a positive result, more hair is extracted from the original batch for the Extraction stage. This phase involves extracting drugs from hair at a much lower concentration than other methods (e.g., urine or saliva), explaining why hair drug screening is the hardest to perform.
Any positively screened samples undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. If needed, samples are washed before confirmation as well. The lab process from Accessioning through Confirmation is scrutinized following both the CAP (College of American Pathologists) Hair criteria and the accreditation to ISO / IEC 17025 standards.
