Hair analysis is now recognized as an effective method for identifying drug and alcohol consumption. It offers a comprehensive record of substance use, capturing markers within the strands of hair as they grow. Hair samples taken close to the scalp can provide a look back period of up to three months for drug and alcohol usage. This method is easy to collect, hard to tamper with, and convenient for shipping.
A sample measuring approximately 1.5 inches and containing around 200 strands (similar in size to a #2 pencil) near the scalp can yield 100mg of hair, which is optimal for both screening and confirmation processes. For EtG testing, add-ons, or tests exceeding 10-panel, it’s advised to have 150mg of the specimen. Using a jeweler's scale is recommended to measure the sample. If scalp hair is not viable, a comparable amount of body hair can be provided. When referencing head hair, it pertains solely to scalp hair, while body hair encompasses all other types of hair (facial, axillary, etc.).
Process Overview
Four principal phases mark the laboratory evaluation of a drug test: Accessioning, Screening, Extraction, and Confirmation.
In the Accessioning phase, the sample is initially integrated into the lab’s system. The process includes ensuring the sample's integrity by verifying proper sealing and shipping, assigning an arbitrary LAN (Laboratory Accessioning Number), and recording any additional data absent from electronic custody systems.
Screening serves as a preliminary assessment to detect drug presence. Though this method efficiently eliminates drug use in most cases, a positive outcome necessitates further verification for legal acceptability. Samples showing potential positive results during Screening require subsequent Confirmation.
Should a sample indicate likely positive findings during Screening, additional strands are extracted from the initial sample for further preparation in the Extraction phase. Here, drugs are isolated from the hair at concentrations far lower than those in other testing methods (e.g., urine or oral fluids), underscoring the complexity of performing hair drug analysis.
Confirmation of positive screening results is executed using techniques like GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples undergo necessary cleaning. The overarching laboratory procedure, spanning from Accessioning to Confirmation, undergoes scrutiny under both the CAP (College of American Pathologists) Hair criteria and compliance with ISO/IEC 17025 standards.
