Hair analysis is recognized as an effective method for identifying substance and alcohol consumption. Hair captures a prolonged timeline of drug and alcohol use by encasing biomarkers within the strands as hair grows. When sampled near the scalp, it can offer up to a three-month window for detecting drugs and alcohol. Hair collection is straightforward, relatively hard to tamper with, and simple to transport.
A sample of 1.5 inches consisting of around 200 hair strands (similar in size to a #2 pencil) from the scalp provides 100mg of hair, which is ideal for both screening and confirmation. For EtG evaluations, additional tests, or panels exceeding 10, a 150mg amount of the sample is advised. It is recommended to measure the sample on a jeweler’s scale. If scalp hair cannot be obtained, a comparable quantity of body hair is an alternative. Head hair exclusively refers to scalp hair, while body hair includes other types of hair (facial, axillary, etc.).
Process Overview
The drug testing process in a lab follows four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning covers the initial phase of incorporating a sample into the lab’s system. This step involves ensuring the sample is properly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and entering any extra data not available electronically via the chain of custody system.
Screening provides an initial, swift analysis for drugs. While it is a cost-efficient method to eliminate drug presence in most samples, a positive screening result must be verified to be legally valid. Samples showing a presumptive positive in Screening demand further confirmation.
Should a sample show presumptive positivity at the Screening stage, additional hair is extracted from the initial sample for the Extraction phase. Here, drugs are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening notably complex.
For any positive Screening outcomes, Confirmation is carried out using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples marked presumptive positive undergo a wash before Confirmation as necessary. The complete lab procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO/IEC 17025 standards.
