Hair evaluation has emerged as an impactful means for identifying drug and alcohol consumption. Hair captures long-term histories of alcohol and drug use by confining biomarkers within the strands of growing hair. When taken near the scalp, hair can offer up to roughly a three-month window for spotting alcohol and drug consumption. Hair is straightforward to collect, relatively hard to tamper with, and simple to transport.
A 1.5-inch segment from around 200 strands of hair (roughly matching a #2 pencil's width) nearest to the scalp will yield 100mg of hair, optimal for screening and validation. For EtG, additional substances, and/or evaluations exceeding 10 panels, a 150mg sample is advised. We suggest measuring the sample on a jeweler's scale. If scalp hair is not present, a similar amount of body hair can be gathered. When mentioning head hair, we specifically mean scalp hair alone. Body hair denotes all other hair types (facial, axillary, etc.).
Process Overview
The primary steps in the laboratory workflow of generating a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the foundational handling of a sample into a lab’s infrastructure. This includes ensuring the sample was correctly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent from an electronic chain of custody system.
Screening functions as the preliminary swift assessment for drugs of misuse. Although Screening is an economical means to exclude drug use in most samples, a positive screen must be substantiated for acceptance in legal contexts. Samples indicated as presumptively positive in Screening necessitate subsequent confirmation.
Should a sample be tentatively positive in the Screening phase, additional hair is drawn from the original specimen and readied for Extraction. Here, drugs are extracted from hair at significantly lower concentrations compared to other techniques (e.g., urine or oral fluid), which renders hair drug screening the most challenging technique to execute.
Verification of any positive screening outcome is executed through GC/MS, GC/MS/MS or LC/MS/MS. All samples indicated as presumptively positive undergo washing before confirmation as required. The full laboratory sequence from Accessioning to Confirmation is assessed under the CAP (College of American Pathologists) Hair designation and certified to ISO / IEC 17025 standards.
