Hair examinations have gained recognition as a vital resource for identifying drug and alcohol consumption. Hair captures a prolonged record of alcohol and narcotics by embedding biomarkers within the strands of hair as they grow. When gathered close to the scalp, it can yield a detection range extending up to about 3 months for identifying alcohol and other substances. Collecting hair is straightforward, relatively challenging to tamper with, and convenient for shipping.
A sample measuring 1.5 inches, comprising roughly 200 hair strands (comparable to the diameter of a #2 pencil), gathered closest to the scalp will yield 100mg of hair, ideal for analysis and verification. For EtG, additional tests, and/or analyses beyond 10 panels, a 150mg sample is advised. We suggest using a jeweler’s scale to measure the specimen. If scalp hair is not available, a similar amount of body hair can be obtained. Mention of head hair specifically indicates scalp hair. Body hair suggests all other hair types (facial, axillary, etc.).
Process Overview
The process in a laboratory for analyzing a drug test result comprises four key phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the introductory handling of a sample within a laboratory's framework. It involves confirming the proper sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and finalizing any surplus data input not facilitated by an electronic chain of custody system.
Screening is an initial swift evaluation for detecting drugs of abuse. While Screening serves as an economical method to eliminate drug usage for the majority of samples, a positive result requires validation to be accepted in legal proceedings. Samples preliminarily positive in Screening necessitate further confirmation.
If a sample tests presumptively positive during the Screening phase, additional hair is extracted from the initial sample and groomed for Extraction. At this stage, drugs are isolated from hair at a substantially lower concentration compared to other methodologies (e.g., urine or oral fluid), rendering hair drug examination the most challenging methodology to execute.
Verification of any positive screening result is executed via GC/MS, GC/MS/MS, or LC/MS/MS. Any samples preliminarily positive are cleansed before confirmation if needed. The comprehensive laboratory procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair standard and the accreditation to ISO / IEC 17025 criteria.
