Hair analysis has emerged as an effective instrument for identifying drug and alcohol consumption. Hair acts as a timeline for alcohol and other substance use by capturing biomarkers within the strands. When sourced near the scalp, it can reveal substance use for up to roughly 90 days. Hair collection is straightforward, somewhat resistant to tampering, and convenient for transport.
A 1.5-inch segment of about 200 hair strands (comparable to the thickness of a #2 pencil) near the scalp yields 100mg, the optimal quantity for analysis. For comprehensive panels over 10 tests, including EtG add-ons, 150mg is suggested. It's advisable to measure the specimen with a jeweler's scale. If scalp hair is unavailable, an equivalent quantity of body hair can be used. "Head hair" refers to scalp hair exclusively, while "body hair" encompasses all other types (e.g., facial, axillary).
Process Overview
The laboratory processing of a drug test result includes four primary steps: Accessioning, Screening, Extraction, and Confirmation.
In Accessioning, samples are first introduced into a lab's system, ensuring they've been properly sealed and transported. A random LAN (Laboratory Accessioning Number) is assigned, with any additional data input completed if not already provided by an electronic custody chain system.
Screening performs a preliminary evaluation for substances of abuse. While cost-efficient for ruling out drug use in most samples, any positive findings must be confirmed for legal admissibility. Samples testing presumptively positive require further validation.
For presumptive positives during Screening, additional hair from the original sample undergoes preparation for Extraction. Drugs are extracted from hair at a substantially lower concentration than other bodily samples (e.g., urine, oral fluid), underscoring the complexity of hair drug testing.
Positive Screening results are verified using GC/MS, GC/MS/MS or LC/MS/MS. Presumptive positive samples are cleansed preliminarily as needed. The complete lab procedure, from Accessioning through Confirmation, complies with CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 standards.
