Hair examinations have emerged as a significant method for identifying drug and alcohol consumption. Hair documents an extended history of substance use by capturing indicators within the fibers of the developing hair strand. When collected near the scalp, hair can reveal drug and alcohol use for nearly a three-month period. Hair is straightforward to collect, challenging to tamper with, and simple to transport.
A 1.5-inch section of roughly 200 hairs (approximate size of a #2 pencil) nearest the scalp yields 100mg, which is the optimal sample size for analysis and confirmation. For EtG, additional tests, and/or panels beyond ten, 150mg of the specimen is advised. We suggest measuring the specimen with a jeweler’s scale. Should scalp hair be unavailable, a comparable amount of body hair may be obtained. Head hair specifically refers to scalp hair exclusively. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The drug test laboratory processing involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary step of integrating a sample into a laboratory’s framework. This phase entails ensuring the sample was sealed and dispatched correctly, assigning a random LAN (Laboratory Accessioning Number), and inputting any further information absent from an electronic chain of custody record.
Screening is a preliminary swift evaluation for drugs of abuse. Although Screening is an economical approach to rule out drug use in the bulk of samples, a positive screen must be validated for courtroom acceptability. All presumptively positive samples during Screening necessitate a follow-up confirmation.
When a sample tests presumptively positive during Screening, more hair is acquired from the initial specimen and readied for Extraction. This step involves extracting drugs from hair at significantly reduced concentrations than other methods (e.g., urine or oral fluid), which is why hair drug screening is considered the most challenging method to execute.
Confirmation of any positive Screening result is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are deemed presumptively positive are cleansed before confirmation as needed. The whole laboratory process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and accredited to ISO / IEC 17025 standards.
