Hair analysis has emerged as a formidable method for identifying drug and alcohol consumption. The hair captures long-term indicators of alcohol and other substances by embedding biomarkers within the strands of the hair as it grows. When harvested near the scalp, hair can offer up to a roughly 3-month timeframe for detecting alcohol and other drugs. Collecting hair is straightforward, relatively hard to tamper with, and convenient to transport.
A 1.5-inch portion of around 200 hairs (approximately the dimension of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal amount for examination and authentication. For EtG, additional tests, and/or those exceeding 10 panels, 150mg of the hair is advisable. We suggest measuring the sample using a jeweler’s scale. If scalp hair is not available, an equivalent quantity of body hair may be utilized. References to head hair strictly mean scalp hair. Body hair encompasses all other hair forms (facial, axillary, etc.).
Process Overview
The principal stages in processing a drug test in the laboratory are Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the preliminary integration of a specimen into a laboratory’s framework. This involves confirming the sample’s seal and proper shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry not furnished by a digital chain of custody mechanism.
Screening entails a preliminary brief examination for signs of drug misuse. While Screening is economical for dismissing drug usage in most samples, a positive screen requires confirmation for legal admissibility. Samples presumptively positive in Screening need subsequent confirmation.
Should a sample be presumptively positive during the Screening stage, additional hair is taken from the initial sample and set up for Extraction. In this step, drugs are separated from hair at a far lower concentration than other methods (e.g., urine or oral fluid), which is why hair drug analysis is the most intricate method to execute.
Confirmation of any positive screening outcome is executed through GC/MS, GC/MS/MS or LC/MS/MS. All samples considered presumptively positive are washed before confirmation as necessary. The entire lab process from Accessioning to Confirmation undergoes review under both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.
