Hair analysis has emerged as an effective method for identifying the use of narcotics and alcohol. Hair captures a prolonged history of substance use by embedding biomarkers within the fibers of the developing hair strand. When garnered near the scalp, it can offer an approximate three-month timeframe for detecting alcohol and drugs. Hair sampling is straightforward, relatively resistant to tampering, and convenient to transport.
A 1.5-inch segment composed of roughly 200 hair strands (similar in size to a #2 pencil) closest to the scalp yields 100mg, ideal for both screening and confirmation testing. For EtG, add-ons, or tests exceeding 10 panels, a 150mg specimen is advisable. We suggest measuring the sample with a jeweler’s scale. In the absence of scalp hair, an equivalent amount of body hair can be utilized. "Head hair" refers specifically to scalp hair, whereas "body hair" encompasses all other types (such as facial or axillary hair).
Process Overview
The laboratory procedure for processing a drug test result comprises Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial integration of a sample into the laboratory's system. This stage ensures proper sealing and shipping of the sample, assigns a random LAN (Laboratory Accessioning Number), and fulfills any additional data entry not covered by an electronic chain of custody system.
Screening provides an initial rapid examination for substances of abuse. While it's cost-efficient for ruling out drug use in most cases, positive screening results must be verified to be valid in legal contexts. Samples deemed presumptive positive during Screening necessitate further confirmation.
Should a sample test positive during Screening, additional hair is extracted from the original sample for further analysis. During Extraction, substances are isolated from hair at lower concentrations compared to other techniques (such as urine or oral fluid), underscoring the complexity of hair drug screening.
Confirmation for any positive Screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positives undergo necessary washing. The entire process from Accessioning to Confirmation is reviewed in compliance with CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.
