Hair testing is recognized as a robust method for detecting drug and alcohol consumption. Hair strands encapsulate biomarkers as they grow, offering an extended timeline for monitoring alcohol and drugs. When taken from near the scalp, hair can reveal a drug usage history of up to three months. It's straightforward to gather, hard to tamper with, and convenient to send for analysis.
A 1.5-inch strand collection from near the scalp, approximately 200 individual hairs (roughly like a #2 pencil), yields 100mg, which is best for screening and confirmation. For those requiring EtG, add-ons, and beyond 10-panel tests, it's advisable to use 150mg of the sample. We suggest using a jeweler's scale for measurement. In the absence of scalp hair, body hair can be used as an alternative. "Head hair" refers solely to scalp hair, whereas "Body hair" encompasses other types (e.g., facial, axillary).
Process Overview
The core stages in laboratory processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the preliminary integration of a specimen into a lab's process. This step validates the correct sealing and dispatch of the sample, the assignment of a random LAN (Laboratory Accessioning Number), and finalizes any supplementary data input absent in the electronic chain of custody.
Screening is an initial swift evaluation for substances of abuse. Although a cost-efficient means to dismiss drug presence in most cases, a screen returning positive requires confirmation for legal acceptability. Any presumptive positives identified in Screening must undergo secondary confirmation.
For samples with presumptive positives from Screening, additional hair is extracted from the original sample for use in Extraction. Drugs are drawn from hair at a significantly reduced concentration compared to other methods (such as urine or saliva fluid), rendering hair drug screening the most challenging method.
Confirming a positive screening outcome involves using GC/MS, GC/MS/MS, or LC/MS/MS. Samples with presumptive positives are cleaned before confirmation as necessary. The entire process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.
