Recently, hair follicle drug testing has been increasingly adopted in drug testing procedures. Numerous employers, courts, and Substance Abuse professionals are opting for a hair drug test over a typical urine test. Hair follicle tests serve those with strict drug-use policies, individuals on probation, and in legal proceedings. These tests offer a significant benefit with up to a 90-day detection window, using an observed collection that's challenging to tamper with. However, for detecting recent drug use within the past 5 days, urine tests remain more precise.

Hair testing has emerged as an effective method for detecting drug and alcohol consumption. Hair strands capture biomarkers that reveal drug and alcohol usage over extended periods. When collected close to the scalp, hair can offer nearly a 3-month window for detecting alcohol and other drugs. This method of collection is straightforward, challenging to tamper with, and simple to transport.
A 1.5-inch sample containing roughly 200 hair strands (similar in size to a #2 pencil) taken from the scalp gives 100mg of hair, which is ideal for both screening and confirmation purposes. For tests like EtG, add-ons, or those exceeding 10 panels, a specimen of 150mg is advised. We suggest using a jeweler’s scale for precise weighing. If scalp hair is inaccessible, a similar quantity of body hair can be used. "Head hair" refers only to scalp hair, and "body hair" covers all other types (e.g., facial, axillary).
Process Overview
The lab processing of a drug test result involves four crucial stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into a laboratory's workflow. This step verifies the proper sealing and shipment of the sample, assigns a random Laboratory Accessioning Number (LAN), and completes any extra data entry not included in an electronic chain of custody system.
Screening serves as a preliminary assessment for drugs of abuse. While cost-effective for eliminating drug use in most samples, a positive screening outcome requires confirmation to be valid in legal proceedings. Any samples deemed presumptively positive during Screening require further confirmation.
For samples deemed presumptively positive at the screening stage, additional hair is extracted from the original sample for Extraction. This involves extracting drugs at lower concentrations compared to methods like urine or oral fluid testing, making hair drug screening one of the most intricate methodologies.
Confirmation of positive screening results is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation as necessary. A complete review of the laboratory process from Accessioning to Confirmation is carried out under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO/IEC 17025 standards.
