Hair analysis is now recognized as an effective means for identifying drug and alcohol consumption. Hair offers an extended history of alcohol and drugs by embedding biomarkers in the strands of growing hair. When taken near the scalp, hair can deliver up to approximately a 3-month timeframe for detecting alcohol and drugs. Hair collection is straightforward, somewhat resistant to tampering, and simple to transport.
A 1.5-inch section of around 200 hair strands (about the diameter of a #2 pencil) nearest to the scalp can yield 100mg of hair, the perfect amount for both preliminary and confirmatory testing. For EtG, additional tests, or panels exceeding 10 tests, 150mg of hair is suggested. Using a jeweler’s scale to weigh the hair sample is advised. In cases where scalp hair is unavailable, the same volume of body hair can be used. Reference to head hair pertains exclusively to scalp hair, while body hair includes other types (facial, axillary, etc.).
Process Overview
The drug testing protocol in a laboratory is comprised of four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial stage of integrating a sample into a lab's system. It involves confirming that the sample was correctly sealed and transported, generating a random LAN (Laboratory Accessioning Number), and filling in any data that isn't provided by electronic custody systems.
Screening serves as an initial, rapid assessment for drug misuse. Although Screening is an economical approach to exclude drug use in most cases, any positive screening finding must be validated for court acceptance. Samples with potential positive results in Screening require a supplementary confirmation.
Should a sample show a potential positive result in the Screening phase, additional hair is retrieved from the original sample and readied for Extraction. During this phase, drugs are removed from hair at a much lower concentration compared to other methods (e.g., urine or oral fluid), which is why hair drug analysis is considered the most challenging technique to execute.
Confirmation of any positive screening outcome is carried out using GC/MS, GC/MS/MS or LC/MS/MS methodologies. All samples with potential positives are cleansed prior to confirmation when required. The complete laboratory procedure from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 standards accreditation.
