Recently, drug testing strategies have increasingly relied on hair follicle analysis. Various employers, judicial systems, and substance abuse counselors prefer hair tests over traditional urine methods. Employers with strict no-drug-use rules, legal entities, and parolees often select hair follicle testing. The key advantage is its extended detection time—up to 90 days—collected via an observed process, and almost impossible to tamper with, though urine tests remain the gold standard for recent drug use within 5 days.

The use of hair testing has emerged as an effective method for identifying drug and alcohol consumption. Hair captures a long-term record of alcohol and drugs by retaining biomarkers within the hair fiber strands. When cut near the scalp, hair can offer an approximate 3-month detection period for substances. Collecting hair is easy, challenging to tamper with, and straightforward to transport.
A 1.5-inch sample of roughly 200 hair strands (about the thickness of a #2 pencil) next to the scalp will provide 100mg of hair, the optimal sample for analysis. For tests like EtG, add-ons, or more than 10 panels, a 150mg sample is preferred. It's advised to measure the hair sample using a jeweler’s scale. If no scalp hair is available, an equivalent amount of body hair can be used. When discussing head hair, we mean scalp hair exclusively, whereas body hair encompasses other types (e.g., facial, axillary).
Process Overview
The key steps in processing a drug test result in a laboratory are Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial handling of a sample in a lab's system. This process includes confirming the sample was properly sealed and sent, assigning a unique LAN (Laboratory Accessioning Number), and completing extra data entry if an electronic chain of custody system lacks it.
During Screening, there is an initial assessment for drugs of abuse. Screening is a cost-efficient way to identify the absence of drug use in most samples, but a positive screen must be validated to be acceptable in legal settings. Samples that indicate positive in Screening need a follow-up confirmation.
Should a sample test positive in the Screening phase, additional hair is taken from the original sample and prepared for Extraction. In this step, drugs are extracted from hair at much lower concentrations than other methods (e.g., urine or oral fluid), making hair drug screening the most challenging method to execute.
Confirmation of a positive screening result utilizes GC/MS, GC/MS/MS, or LC/MS/MS methods. Presumptive positive samples are washed as necessary before confirmation. The entire lab process from Accessioning to Confirmation is inspected under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Note: Even though often termed as "hair follicle tests", the analysis targets the hair strand, not the follicle beneath the scalp.
