Recently, drug testing methods increasingly incorporate hair follicle tests. These tests are being chosen by employers, courts, and Substance Abuse experts over traditional urine tests. Courts, employers with strict no-drug policies, and probationers favor hair tests due to their longer detection span — often up to 90 days — and the difficulty in tampering with samples. However, urine tests remain the go-to for detecting recent drug use within five days.

Hair screening has gained recognition as an effective means for identifying alcohol and drug consumption. Hair encapsulates a comprehensive timeline of substance use by sequestering biomarkers within the strands as they grow. When taken near the scalp, a hair sample can reveal drug and alcohol use over a timeframe of roughly 90 days. Collection of hair is straightforward, tampering with the sample is relatively challenging, and it can be transported with ease.
A 1.5-inch sample consisting of approximately 200 hair strands (comparable to the thickness of a #2 pencil) close to the scalp provides 100mg of hair, which is ideal for testing and validation. For tests involving EtG or exceeding 10 panels, a 150mg sample is suggested. It's advisable to measure the sample using a jeweler’s scale. In the absence of scalp hair, a similar quantity of body hair is acceptable. By head hair, we mean scalp hair alone. Body hair encompasses other varieties (facial, axillary, etc.).
Process Overview
The quartet of essential steps in lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the initial phase where a sample enters a lab’s database. This step involves ensuring the sample’s seal and shipment are intact, allocating a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data input absent in an electronic chain of custody framework.
Screening is a preliminary evaluation for detecting substance abuse. Although Screening can economically excluding drug consumption in most cases, a positive finding mandates validation for legal proceedings. Samples testing positive during Screening necessitate additional corroboration.
In cases where Screening indicates a presumptive positive, additional hair is extracted from the original sample to undergo Extraction. Drug concentrations are isolated from hair via this phase, which operates at minimal concentration levels compared to other approaches (like urine or saliva), making hair drug assessment the most challenging to execute.
Confirmation of positive screening results is performed using GC/MS, GC/MS/MS, or LC/MS/MS methods. Prior to confirmation, all presumptive positive samples are cleansed as required. The comprehensive lab procedure from Accessioning to Confirmation is regulated under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
