Hair analysis is recognized as an effective means for identifying drug and alcohol consumption. Hair captures a long-term timeline of alcohol and drug use by embedding biomarkers within the fibers of the growing hair shaft. When sourced near the scalp, hair can reveal a detection period of up to three months for alcohol and other substances. The collection of hair is straightforward, relatively resistant to tampering, and simple to transport.
A sample of 200 hair strands, measuring 1.5 inches and roughly the width of a #2 pencil, close to the scalp yields 100mg of hair, which is ideal for both screening and confirmation procedures. For EtG tests and/or tests exceeding 10 panels, a sample of 150mg is suggested. It's advisable to weigh the specimen using a jeweler’s scale. Should scalp hair be inaccessible, an equivalent quantity of body hair is an acceptable substitute. "Head hair" specifically refers to scalp hair, while "body hair" encompasses other hair types like facial or axillary hair.
Process Overview
The laboratory processing of a drug test result includes four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the initial stage where samples are logged into the laboratory system. This step ensures the sample was sealed and shipped correctly, assigns a random LAN (Laboratory Accessioning Number), and completes any supplemental data entry absent from an electronic chain of custody system.
Screening serves as an initial quick test for drug abuse. It’s a cost-efficient method to rule out drug usage in most samples; however, a positive screen must be confirmed for legal admissibility. Samples testing presumptively positive in Screening necessitate a follow-up confirmation.
Presumptive positives from the Screening stage lead to additional hair being extracted from the initial sample for the Extraction phase. In this phase, drugs are isolated from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluids), contributing to the complexity of hair drug analysis.
Confirmation of a positive screen is achieved using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Samples deemed presumptively positive are washed prior to confirmation if required. The entire Accessioning to Confirmation laboratory process is scrutinized under the CAP (College of American Pathologists) Hair designation and adheres to ISO / IEC 17025 accreditation standards.
