Hair analysis is now recognized as an efficient method for identifying alcohol and drug consumption. Hair captures a prolonged record of substance intake by embedding biomarkers within the strands as they develop. When taken near the scalp, hair can reveal alcohol and drug use up to nearly a 90-day timeframe. Collecting hair is straightforward, challenging to tamper with, and easy to transport.
A sample of 1.5 inches consisting of roughly 200 hair strands (approximately the thickness of a #2 pencil) nearest to the scalp will yield 100mg of hair, the optimal measurement for both screening and confirmation. For EtG, additional tests, or panels beyond 10, securing 150mg of the sample is advisable. It's recommended to weigh the hair using a jeweler's scale. If scalp hair isn't available, a similar quantity of body hair can be collected. The term head hair specifically refers to scalp hair. Body hair encompasses all other types (face, armpits, etc.).
Process Overview
The four critical steps in processing a drug test result in the lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning initiates the sample's integration into the lab's system. This stage includes checking the sample's seal and shipping integrity, assigning a random LAN (Laboratory Accessioning Number), and completing any remaining data not included by an electronic chain of custody.
Screening offers a rapid initial assessment for drug abuse. While it's an economical method to exclude drug usage for the majority, any positive findings in Screening must be validated for court acceptability. Samples that are presumptively positive in Screening require secondary confirmation.
If Screening yields a presumptive positive, additional hair is drawn from the original sample for Extraction. In Extraction, drugs are isolated from hair at significantly lower concentrations than other methods (such as urine or saliva), making hair drug screening the most challenging to perform.
Confirmation of positive screen results is executed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples are washed before confirmation if necessary. The entire lab procedure from Accessioning to Confirmation is assessed under the CAP (College of American Pathologists) Hair designation and is accredited to ISO / IEC 17025 standards.
