The use of hair testing has gained recognition as a robust method for identifying drug and alcohol consumption. Hair delivers a comprehensive timeline of drug and alcohol intake by embedding biomarkers within the fibers of the hair as it grows. Collecting hair samples near the scalp can offer an approximate detection window of up to 3 months for drugs and alcohol. The collection process for hair is straightforward, it is relatively hard to tamper with, and it is convenient to send.
A sample measuring 1.5 inches, consisting of about 200 hair strands (roughly similar in width to a #2 pencil) nearest to the scalp, provides 100mg of hair, which is considered the optimal amount for both screening and confirmation tests. For EtG, additional analyses, and/or evaluations beyond 10 panels, it is advised to use 150mg of the sample. We suggest using a jeweler’s scale to determine the specimen's weight. If scalp hair cannot be collected, an equivalent quantity of body hair may be used. When mentioning head hair, it specifically refers to scalp hair. Body hair encompasses other types, such as facial and axillary hair.
Process Overview
The laboratory processing involved in deriving drug test results comprises four core steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample undergoes initial processing into a laboratory system. This step ensures the sample was suitably sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and concludes any additional information entry absent from an electronic chain of custody framework.
Screening acts as a preliminary swift assessment for the presence of drugs. While Screening is an economical approach to exclude drug use in most cases, a positive outcome from Screening requires confirmation for court acceptability. Any samples that show a preliminary positive result during Screening necessitate a secondary validation.
In instances where a sample is tentatively positive in the Screening phase, additional hair is extracted from the initial collection and readied for Extraction. During this phase, drugs are extracted from hair at significantly lower concentrations than other methods (such as urine or oral fluid), which is why hair drug screening stands as a considerably challenging practice.
Confirmation for any positive Screening results is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as appropriate. The entire laboratory procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair classification and adheres to ISO / IEC 17025 standards.
