Hair analysis is now regarded as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged record of drugs and alcohol by embedding biomarkers within the hair fibers as it grows. Collected near the scalp, hair offers up to a 90-day window for detecting alcohol and drugs. It's straightforward to gather, hard to tamper with, and convenient to transport.
A sample of 1.5 inches with approximately 200 hair strands (roughly the diameter of a #2 pencil) closest to the scalp provides 100mg, the optimal quantity for both screening and further analysis. For EtG, additional tests, and/or those exceeding 10 panels, 150mg is advisable. We suggest using a jeweler's scale for accurate measurement. If scalp hair is not available, a corresponding quantity of body hair may be used. References to head hair pertain solely to scalp hair. Body hair includes all other hair types (facial, axillary, etc.).
Process Overview
The laboratory steps for processing a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves entering a sample into a lab’s records. This process ensures the sample was sealed and sent correctly, assigns a unique LAN (Laboratory Accessioning Number), and completes any extra data inputs missing in a digital chain of custody system.
Screening entails an initial quick assessment for substance abuse. Though Screening is an economical approach to dismiss drug use in most specimens, any positive screen result must be validated for legal admissibility. Any samples flagged as presumptively positive during Screening require further Confirmation.
Should a sample show a presumptive positive during Screening, additional hair is derived from the initial sample for the Extraction phase. During this, substances are extracted from hair at much lower concentrations than in other methods (e.g., urine or saliva); thus, hair drug analysis remains a complex challenge.
The Confirmation process for any positive Screen results employs GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples deemed presumptively positive undergo necessary washing before Confirmation. From Accessioning to Confirmation, the entire lab procedure adheres to CAP (College of American Pathologists) Hair guidelines and ISO/IEC 17025 accreditation standards.

Limitations:
Note: Though often termed "hair follicle tests," the analysis examines the hair strand, not the follicle beneath the scalp.
