Hair assessment has gained relevance as a formidable instrument for identifying drug and alcohol consumption. By capturing biomarkers within the fibers of the developing hair strand, hair offers a chronological record of alcohol and drug use. When sampled near the scalp, hair can furnish a detection period extending up to roughly three months for drugs and alcohol. Collection is straightforward, tampering is somewhat challenging, and transport is efficient.
A sample measuring 1.5 inches, comprising approximately 200 hair strands (comparable to a #2 pencil's thickness) closest to the scalp yields 100mg, which is optimal for both screening and confirmation purposes. For tests such as EtG, add-ons, or panels exceeding 10, a recommended 150mg sample size is advised. Utilizing a jeweler’s scale for specimen weighing is suggested. Should scalp hair be inaccessible, an equivalent quantity of body hair is an acceptable alternative. Reference to head hair strictly pertains to scalp hair, while body hair encompasses other types (like facial, axillary, etc.).
Process Overview
The four pivotal stages in laboratory drug testing include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary phase, involving the integration of a sample into a lab's framework. This step includes confirming that the sample was appropriately sealed and dispatched, generating a unique LAN (Laboratory Accessioning Number), and finalizing any absent data entry not captured by an electronic chain of custody system.
Screening acts as an initial swift examination for drug misuse. As a cost-efficient method, Screening tends to exclude drug use for most samples, although positive results require validation for judicial admissibility. Any presumptively positive Screening samples necessitate subsequent confirmation.
Upon a presumptive positive Screening outcome, additional hair is extracted from the initial sample for Preparation during Extraction. This stage eliminates drugs from hair at comparatively lower concentrations than alternative techniques (such as urine or oral fluid), making hair drug analysis the most complex method to execute.
Verification of any affirmative Screening result utilizes GC/MS, GC/MS/MS, or LC/MS/MS methodologies. All samples deemed presumptively positive undergo requisite washing before Confirmation. The entire procedural sequence from Accessioning to Confirmation undergoes scrutiny according to CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation standards.
