Hair examination is now considered a highly effective means for identifying drug and alcohol consumption. Hair offers an extended timeline of alcohol and drug usage as it captures biomarkers within the growing strand's fibers. When obtained near the scalp, it can offer an approximate 3-month period detection window for substances. Hair collection is straightforward, relatively tamper-resistant, and convenient for transport.
A 1.5-inch segment containing around 200 hair strands (comparable in size to a #2 pencil) nearest to the scalp will yield 100mg, optimal for analysis and verification. For EtG, additions, and/or examinations exceeding 10 panels, a 150mg sample is advisable. A jeweler’s scale is suggested for specimen weighing. If scalp hair is unavailable, a similar volume of body hair may be utilized. Scalp hair specifically references head hair, whereas body hair pertains to all other hair varieties (e.g., facial, axillary).
Process Overview
There are four primary phases in the lab processing of a drug test outcome: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the preliminary input of a specimen into the lab’s system, which includes verifying that the sample was secured and sent correctly, allocating a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent from an electronic chain of custody system.
Screening consists of an initial rapid evaluation for drug abuse. Screening is an economical method to exclude drug usage in most cases; however, a positive result requires validation to be court-admissible. Samples with presumptive positive results in Screening necessitate additional confirmation tests.
If a specimen is indicative of positivity during the Screening phase, supplementary hair is extracted from the original sample for Extraction. In this phase, drugs are isolated from the hair at much lower concentrations than other methods (such as urine or oral fluids), making hair drug screening the most challenging methodology.
Confirmation of any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive specimens are washed prior to confirmation, if necessary. The entire lab procedure from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair classification and the ISO/IEC 17025 accreditation standards.
