Utilizing hair testing is regarded as an effective resource for uncovering drug and alcohol consumption. Hair offers a prolonged record of substance use by capturing biomarkers within the strands of growing hair. When gathered near the scalp, hair can reveal substance usage up to about a 3-month timeframe for alcohol and drugs. Collecting hair is straightforward, relatively hard to tamper with, and simple to transport.
A 1.5-inch segment consisting of roughly 200 strands of hair (comparable to the thickness of a #2 pencil) closest to the scalp can provide 100mg of hair, which is the optimal amount for both screening and confirmation. For EtG, add-ons, or panels exceeding 10, a 150mg sample is advised. We suggest weighing the hair using a jeweler’s scale. If scalp hair is unobtainable, a similar quantity of body hair may be used. When discussing head hair, this refers specifically to scalp hair. Body hair encompasses all other hair varieties (facial, axillary, etc.).
Process Overview
The four key phases in lab processing of a drug test result comprise Accessioning, Screening, Extraction, and Confirmation.
Accessioning comprises the initial analysis of a specimen into a lab’s system. This step ensures the sample is sealed and dispatched correctly, assigns a random LAN (Laboratory Accessioning Number), and completes any missing data entry not included by an electronic chain of custody system.
Screening involves a preliminary brisk examination for abusive drugs. While Screening is a financially viable method to eliminate drug usage for most samples, a positive screen must be corroborated for legal acceptability. Samples that are initially positive in Screening necessitate further confirmation.
If Screening suggests a sample is positive, additional hair is extracted from the original sample for Extraction. During this phase, drugs are sourced from hair at a significantly lower concentration than other techniques like urine or oral fluid, making hair drug screening a challenging methodology.
Confirmation of any positive screening outcome is performed via GC/MS, GC/MS/MS, or LC/MS/MS. Every presumptive positive sample undergoes washing before confirmation as required. The comprehensive laboratory procedure from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair classification and accreditation to ISO / IEC 17025 standards.
