The use of hair follicle drug testing in recent years has been on the rise. Many workplaces, judicial systems, and Substance Abuse authorities are opting for hair tests over traditional urine ones. Hair tests are favored by employers with stringent drug policies, legal entities, and probation officers. The key advantage of hair tests is the extended detection period of about 90 days, with collection under supervision, thus making it hard to tamper. However, urine tests remain the preferred choice for detecting recent drug use within the first 5 days.

Hair analysis has emerged as a significant method for identifying drug and alcohol consumption. Hair strands can archive an extended history of substance use by encapsulating biomarkers within the fibers of hair as it grows. When obtained near the scalp, hair offers an approximate detection period of up to 90 days for alcohol and other drugs. Collection is straightforward, the likelihood of tampering is low, and shipping is efficient.
A sample of 1.5 inches consisting of roughly 200 hair strands (equivalent to the width of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal amount for testing and validation. For EtG, additional tests, and tests exceeding 10 panels, 150mg is advisable. Using a jeweler’s scale for measurement is suggested. If scalp hair is scarce, an equivalent quantity of body hair can be used. When discussing head hair, it exclusively refers to scalp hair. Conversely, body hair encompasses all other types such as facial and axillary hair.
Process Overview
In hair testing, the primary steps are Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial integration of the sample into the laboratory’s processing system. This step ensures the sample was properly sealed and transported, assigns a unique LAN (Laboratory Accessioning Number), and completes any outstanding data entry absent from electronic custody systems.
Screening entails an initial rapid assessment for substances of abuse. It is an economical approach to preliminarily eliminate drug use from most samples, but a positive screen needs verification to hold up in legal circumstances. Presumptively positive screens necessitate additional validation.
Should a sample prove presumptively positive during Screening, more hair from the original sample is gathered for Preparation and Extraction. Drugs are extracted from hair at lower concentrations than other methods (e.g., urine or oral fluid), which elevates the complexity of hair drug screening.
Positive screening results are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS procedures. Presumptive positives undergo a wash prior to Confirmation. The complete laboratory process from Accessioning to Confirmation adheres to both CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.
