Hair analysis has gained recognition as a robust approach for identifying drug and alcohol consumption. Hair maintains a record of substances over the long term due to biomarker retention within its strands. Acquired near the scalp, hair can reveal drug and alcohol use for up to a three-month period. The collection process is straightforward, tampering is challenging, and transportation is hassle-free.
A 1.5-inch segment of approximately 200 hair strands (comparable to a #2 pencil’s width) closest to the scalp yields 100mg, the optimal quantity for testing. For EtG, enhancements, or tests exceeding 10 panels, a 150mg sample is advised. Utilize a jeweler’s scale for accurate measurement. If scalp hair is not accessible, a similar quantity of body hair may be used. Reference to head hair pertains solely to scalp hair, while body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory process of a drug test result involves four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step, integrating a sample into the lab’s system. This involves ensuring the sample was sealed and transported properly, assigning a unique LAN (Laboratory Accessioning Number), and completing any extra data entry omitted by an electronic chain of custody.
Screening is a preliminary assessment for drugs of abuse. Though economical, positive screening results must be confirmed to be legally valid. Any samples indicating a positive result in Screening undergo secondary confirmation.
Presumptive positives in Screening lead to additional hair being extracted and readied for Extraction. Here, drugs are removed from hair at lower concentrations than in other methods (e.g., urine or saliva), making hair testing the most technical method.
Confirmation of a positive screening outcome uses GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples are washed pre-confirmation as necessary. The entire process, from Accessioning to Confirmation, is rigorously checked under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
