Hair analysis is increasingly recognized as an effective means for identifying drug and alcohol consumption. Hair acts as a repository for long-term substance history by embedding biomarkers within the strands. When cut close to the scalp, it can reveal alcohol and drug use over a span of up to roughly three months. Collecting hair is straightforward, challenging to tamper with, and convenient to send.
An ideal sample for evaluating and confirming drug use is a 1.5-inch segment consisting of around 200 hairs (approximately the thickness of a #2 pencil) from the scalp, yielding 100mg. For EtG assessments, additional tests, or those exceeding ten panels, 150mg is advisable. It's best to weigh the sample on a jeweler’s scale. If scalp hair isn't available, a similar amount of body hair can be used. By "head hair", we mean only scalp hair. "Body hair" includes all other types (facial, axillary, etc.).
Process Overview
The primary phases in processing a drug test result in the lab include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first step of incorporating a sample into the lab's system. This step ensures the sample is properly sealed and shipped, assigns a unique LAN (Laboratory Accessioning Number), and completes any necessary data entry not included in an electronic chain of custody.
Screening is an initial, quick assessment for substances of abuse. While it's a cost-effective method to eliminate negative samples, a positive Screening result must be confirmed for legal admissibility. Any samples testing positive in Screening necessitate a secondary confirmation.
When a sample tests positive during Screening, more hair is taken from the collected specimen for Extraction. In this phase, drugs are derived from the hair at a significantly lower concentration than in other procedures (e.g., urine or oral fluid), which is why hair drug screening is particularly challenging to conduct.
Positive Screening results are confirmed using GC/MS, GC/MS/MS or LC/MS/MS methodologies. Presumptive positive samples are washed if needed before confirmation. The entire procedure from Accessioning to Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.
