Hair analysis is viewed as an effective method for identifying drug and alcohol consumption. It offers a comprehensive history of alcohol and drug use by capturing biomarkers within the strands of growing hair. When sourced close to the scalp, hair samples can demonstrate up to a 3-month detection timeline for alcohol and drugs. Hair is effortless to obtain, challenging to tamper with, and convenient to transport.
A sample measuring 1.5 inches from around 200 hair strands (approximating the thickness of a #2 pencil) near the scalp will yield 100mg of hair, the optimal quantity for screening and validation. For EtG, additional analyses, and/or tests exceeding 10 panels, a 150mg sample is advisable. It’s recommended to measure the sample using a jeweler’s scale. If scalp hair is not present, an equivalent amount of body hair may be used. When mentioning head hair, it specifically refers to scalp hair. Body hair encompasses all other varieties (facial, axillary, etc.).
Process Overview
The four critical stages in processing a laboratory drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary processing of a specimen into a lab’s system, ensuring that the specimen was sealed and shipped accurately, assigning a random LAN (Laboratory Accessioning Number), and fulfilling any supplementary data entry not covered by an electronic chain of custody system.
Screening is a preliminary expedited check for drugs of abuse. While Screening is a cost-efficient approach to exclude drug usage on most samples, a positive outcome requires validation for court admissibility. Samples that show a presumptive positive in Screening need subsequent confirmation.
If a sample exhibits a presumptive positive in the Screening phase, additional hair is extracted from the original sample for Extraction. During this phase, drugs are isolated from hair at a substantially lower concentration than in other methodologies (e.g., urine or oral fluid), underscoring why hair drug testing is the most intricate methodology to execute.
Confirmation of any positive screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo washing prior to confirmation as necessitated. The complete laboratory process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
