Hair analysis is recognized as an effective means for identifying substance and alcohol consumption. Hair strands encapsulate biomarkers within their fibers, offering a prolonged overview of alcohol and drug usage. Hair samples obtained near the scalp can reveal a detection span of up to three months for alcohol and drugs. The collection of hair is straightforward, challenging to tamper with, and simple to send.
A 1.5-inch segment composed of approximately 200 hair strands (comparable in size to a #2 pencil) gathered close to the scalp yields 100mg of hair, the optimal sample for both screening and verification. For EtG, additional screenings, and/or tests exceeding 10 panels, 150mg of the sample is advised. Utilizing a jeweler’s scale to measure the specimen is recommended. Should scalp hair be inaccessible, a similar quantity of body hair can be taken. When discussing head hair, it pertains exclusively to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
Conducting a drug test result in a lab involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.
The Accessioning phase is the initial step of integrating a sample into the laboratory's framework. It checks whether the sample was appropriately sealed and transported, assigns a unique LAN (Laboratory Accessioning Number), and resolves any additional data entry not captured by an electronic chain of custody system.
Screening is a preliminary rapid assessment for substance abuse. Though Screening is budget-friendly for dismissing drug use in most samples, any positive findings need confirmation for court validity. Samples testing presumptively positive in Screening require subsequent verification.
For presumptive positive results in Screening, extra hair is extracted from the original specimen and processed in the Extraction stage. Here, substances are extracted from hair at a significantly lower concentration compared to other methods (e.g., urine or oral fluid), underscoring the complexity of hair drug analysis.
Positive results from Screening are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo necessary washing prior to confirmation. This entire laboratory procedure from Accessioning to Confirmation adheres to both CAP (College of American Pathologists) Hair specifications and ISO / IEC 17025 accreditation standards.
