In recent times, drug testing often incorporates a hair follicle test. Many businesses, judicial systems, and Substance Abuse professionals favor hair drug tests over standard urine assessments. Employers with strict drug policies, courts, and individuals on probation utilize hair follicle tests. The key advantage is a significantly longer drug use detection window of up to 90 days, observed during collection, and nearly impossible to manipulate. Nevertheless, urine tests remain precise for recently used substances within 5 days.

Hair analysis is now recognized as an effective method for identifying drug and alcohol consumption. Hair retains a historical record of alcohol and drug use by incorporating biomarkers into the strands as they grow. Close-to-scalp samples can reveal drug and alcohol use over a period of up to roughly 90 days. It's straightforward to collect hair, less prone to tampering, and convenient to transport.
A sample that is 1.5 inches in length with about 200 strands (similar in size to a #2 pencil) when taken from the scalp yields 100mg of hair, which is ideal for testing and confirmation. For EtG, additional tests, or those with over 10 panels, a recommended 150mg of hair should be collected. It's advised to weigh the specimen using a jeweler’s scale. If scalp hair isn't accessible, an equivalent amount of body hair can be used. The term head hair refers specifically to scalp hair, while body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test encompasses four crucial steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial stage where a sample is systematically processed into the lab's framework. This step ensures the sample was correctly sealed and dispatched, assigns a unique LAN (Laboratory Accessioning Number), and completes any required data input not fulfilled by an electronic chain of custody system.
Screening performs a preliminary assessment for substances of abuse. Although this is a cost-efficient method for eliminating drug use in most samples, a positive result must be affirmatively confirmed to be court-admissible. Samples that test positive presumptively during Screening necessitate a follow-up confirmation.
Should a sample indicate a presumptive positive in Screening, further hair is extracted from the original sample and processed for Extraction. During this phase, drugs are extracted from the hair at far lower concentrations compared to other methods (e.g., urine or oral fluid), underscoring the complexity of hair drug screening.
An affirmative Screening result requires Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. Samples testing positive presumptively undergo washing as needed before Confirmation. The entire procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.
