Hair analysis is recognized as a valuable means for identifying drug and alcohol consumption. By capturing biomarkers within the fibers of developing hair strands, hair provides an extensive timeline of substance use. A sample collected near the scalp can yield up to a 3-month observation window for detecting alcohol and other drugs. Hair is straightforward to gather, hard to tamper with, and convenient for transport.
A hair sample of 1.5 inches, consisting of about 200 strands (equivalent to the thickness of a #2 pencil), nearest to the scalp provides 100mg of hair, which is perfect for both screening and confirmation. For EtG, additional analyses, and/or for tests exceeding 10 panels, a sample of 150mg is advised. It's best to assess the sample's weight utilizing a jeweler’s scale. In cases where scalp hair isn't available, an equivalent portion of body hair might be used. When mentioning head hair, we specifically mean scalp hair, whereas body hair encompasses all other varieties (such as facial, axillary, etc.).
Process Overview
The drug test result process in laboratories is structured into four main phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning signifies the preliminary phase of incorporating a sample into the laboratory's framework. This process includes confirming that the specimen was correctly sealed and transported, generating a random LAN (Laboratory Accessioning Number), and filling in any extra data entry lacking from an electronic chain of custody process.
Screening denotes a swift preliminary assessment for substances of misuse. Screening is an economical approach to exclude drug usage for most samples, yet any positive screen must be verified for legal admissibility. Samples showing potential positives in Screening necessitate a follow-up confirmation.
Should a sample render a presumptive positive during the Screening phase, additional hair is sourced from the original specimen for Extraction preparation. In this phase, substances are extracted from hair at significantly lower concentrations than with other techniques (e.g., urine or saliva), emphasizing hair drug screening's complexity.
To confirm any positive screening outcomes, methods such as GC/MS, GC/MS/MS, or LC/MS/MS are employed. Presumptively positive samples are cleansed before confirmation if needed. The full lab procedure, from Accessioning to Confirmation, undergoes review in line with both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
