Hair analysis is recognized as an effective method for uncovering alcohol and drug consumption. By holding onto biomarkers within the strands, hair presents an extended timeline for drug and alcohol usage history. When strands are taken near the scalp, they offer up to a three-month timeframe for detection. Additionally, hair is straightforward to gather, somewhat resistant to tampering, and convenient for transport.
A small portion of hair, measuring 1.5 inches and comprising roughly 200 strands (approximately the circumference of a #2 pencil), is needed near the scalp to acquire 100mg of hair, which is ideal for both screening and confirmation purposes. For EtG, supplementary tests, or assessments above 10 panels, it's advised to gather 150mg of the specimen. It's suggested to use a jeweler's scale for weighing. Should scalp hair not be an option, a comparable quantity of body hair can be used. When discussing head hair, we mean scalp hair specifically. Body hair includes all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result comprises four major stages: Accessioning, Screening, Extraction, and Confirmation.
In Accessioning, the sample undergoes preliminary handling to integrate it into the laboratory's system. This step confirms correct sealing and shipping, assigns a random LAN (Laboratory Accessioning Number), and completes any additional data entry absent in an electronic chain of custody system.
Screening provides an initial rapid check for substance abuse. Though it’s a cost-effective method to exclude drug usage in most cases, a positive screening requires confirmation for court acceptance. Any sample yielding a presumptively positive result during Screening demands a secondary confirmation.
When Screening indicates a presumptive positive, additional hair from the original specimen is set aside for Extraction. In this stage, the drugs are extracted from hair at notably lower concentrations than in other techniques (e.g., urine or oral fluid), which makes hair drug screening particularly challenging to execute.
Confirmation of any positive screening result is conducted via GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples are washed prior to confirmation as needed. The entire laboratory process from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
