Hair analysis has emerged as a formidable instrument in identifying substance use, including drugs and alcohol. Hair captures a prolonged history of substance exposure by embedding biomarkers within the strands as they develop. When hair samples are obtained near the scalp, they can offer a detection period extending up to roughly 3 months for alcohol and drugs. The collection of hair is straightforward, relatively resistant to tampering, and convenient to transport.
A 1.5-inch hair sample, consisting of approximately 200 strands (analogous to the size of a #2 pencil) situated nearest the scalp, yields 100mg of hair, which is the optimal quantity for both preliminary screening and subsequent confirmation. For EtG, additional analyses, and tests beyond 10 panels, a specimen of 150mg is advocated. We advise using a jeweler’s scale to ensure precise specimen weighing. If scalp hair cannot be obtained, a similar volume of body hair might be utilized. When discussing head hair, we specifically mean scalp hair. Conversely, body hair encompasses all other hair categories (such as facial or axillary hair).
Process Overview
The laboratory procedure for processing a drug test result encompasses four key phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning signifies the preliminary phase where a sample is integrated into the laboratory's framework. Tasks in this phase include ensuring that the sample was correctly sealed and dispatched, generating a random LAN (Laboratory Accessioning Number), and finalizing any extra data entry that is not covered by an electronic chain of custody system.
Screening refers to the initial overview check for substance misuse. Although Screening is an affordable method to exclude drug use for most specimens, a positive result necessitates confirmation to be legally valid. Specimens with a presumptive positive Screening outcome necessitate a subsequent confirmation.
For samples flagged as presumptive positives in the Screening phase, additional hair is extracted from the initial batch and prepped for Extraction. In this process, substances are isolated from hair at a much less concentrated level compared to other techniques (e.g., urine or saliva), which makes hair drug testing the most complex method to conduct.
GC/MS, GC/MS/MS, or LC/MS/MS techniques are used to confirm any positive screening outcomes. Prior to confirmation, all presumptive positive samples undergo a washing step as necessary. The comprehensive laboratory process, from Accessioning through to Confirmation, is scrutinized according to both the CAP (College of American Pathologists) Hair designation and the certification under ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
