Recently, hair follicle drug tests have increasingly become a part of drug testing procedures. Numerous employers, legal systems, and professionals dealing with Substance Abuse demand hair drug tests instead of the traditional urine tests. Employers with strict drug policies, judicial entities, and individuals on probation frequently utilize these tests. Hair follicle drug tests are favored for their ability to detect drug use over an extended timeframe—usually up to 90 days—with a monitored collection method that is nearly impossible to falsify. However, the urine test remains the most accurate option for determining drug use within the past 5 days.

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. By encapsulating biomarkers within the hair strand as it develops, hair provides an extensive history of alcohol and drugs. If taken near the scalp, hair can offer nearly a 3-month detection period for such substances. It is easy to gather, challenging to tamper with, and straightforward to transport.
A sample of 1.5 inches of approximately 200 hair strands (comparable to the width of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the preferred sample size for screening and verification. For EtG, additional tests, and/or panels exceeding 10, a 150mg sample is suggested. Using a jeweler’s scale to weigh the sample is advisable. If scalp hair is not available, the same quantity of body hair might be used. Our reference to head hair specifically indicates scalp hair. Body hair encompasses all other types of hair (facial, axillary, etc.).
Process Overview
The key stages in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first step in integrating a sample into a lab’s system. This step ensures the sample was correctly sealed and shipped, assigns a random Laboratory Accessioning Number (LAN), and handles any additional data input absent from the electronic chain of custody system.
Screening involves an initial scan for illicit drugs. Screening offers a cost-effective approach to ruling out drug usage in most samples, but a positive screen necessitates confirmation for court admissibility. Samples that are presumptively positive in Screening demand a secondary confirmation.
If a sample comes back presumptively positive in the Screening phase, more hair is taken from the original sample for Extraction. During Extraction, drugs are gleaned from hair at concentrations lower than other methodologies (e.g., urine or oral fluid), which makes hair drug analysis particularly challenging.
GC/MS, GC/MS/MS, or LC/MS/MS instrumentation is used to confirm any positive screening results. Prior to confirmation, all samples with presumptive positivity are washed as necessary. The complete lab procedure from Accessioning to Confirmation is evaluated per the CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 standards accreditation.
Advantages of hair drug testing:
Limitations:
Note: Although often termed as "hair follicle tests", the analysis focuses on the hair strand itself, not the follicle beneath the scalp.
