Hair testing is increasingly recognized as an effective mechanism for identifying drug and alcohol use. Hair captures a chronological history of substance use by encasing biomarkers within the hair shaft as it grows. When gathered from the scalp, hair can reveal alcohol and drug usage for up to roughly three months. It is straightforward to collect, challenging to tamper with, and simple to transport.
A section measuring 1.5 inches and consisting of about 200 hair strands (comparable to the diameter of a #2 pencil) near the scalp equates to 100mg, which is the optimal size for both screening and confirmatory purposes. For EtG, additional screenings, and tests exceeding 10 panels, it's advisable to use 150mg of hair. Measuring the hair weight with a jeweler’s scale is suggested. In cases where scalp hair isn't available, a comparable volume of body hair can be obtained. When discussing head hair, we exclusively mean scalp hair, whereas body hair includes all other types of hair (e.g., facial, axillary).
Process Overview
There are four key stages in laboratory analysis of drug test outcomes: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase, where a sample is integrated into the lab's system. This involves checking that the sample is sealed and correctly shipped, assigning it a LAN (Laboratory Accessioning Number), and completing any necessary data input not covered by an electronic chain of custody.
Screening is the initial assessment for drugs of abuse. While being an economical way to exclude drug presence in most samples, a positive screening requires confirmation for court admissibility. Samples that test presumptively positive in screening need further confirmation.
Should a sample be presumptively positive in the Screening stage, additional hair is taken from the original specimen and readied for Extraction. During this phase, drugs are extracted from hair at a much lower concentration than utilizing other methods (such as urine or saliva), making hair drug screening the most intricate technique to conduct.
Confirmation of any positive screening entails using GC/MS, GC/MS/MS or LC/MS/MS. Presumptively positive samples are cleansed prior to confirmation if necessary. The entire process from Accessioning to Confirmation is scrutinized under both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
