Hair analysis is now recognized as an effective method for identifying drug and alcohol consumption. Hair offers an extended record of alcohol and drug use by embedding markers within the strands' structure. When taken from near the scalp, hair captures up to about a 3-month period for substance detection. It's easy to collect, challenging to tamper with, and simple to transport.
To obtain the optimal 100mg sample for testing and validation, a 1.5-inch section comprising approximately 200 hairs (similar to a #2 pencil's diameter) nearest to the scalp is required. For EtG, additional tests, and/or screenings beyond 10 panels, it's advisable to gather 150mg of the sample. It's recommended to measure the sample using a jeweler’s scale. If scalp hair cannot be obtained, a comparable amount of body hair is an alternative. When mentioning head hair, we refer exclusively to scalp hair. Body hair encompasses all other types (e.g., facial, axillary).
Process Overview
The laboratory workflow for determining a drug test result consists of four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the preliminary handling of a sample within a lab's framework. This phase assures that the sample was securely closed and shipped correctly, allocates an arbitrary LAN (Laboratory Accessioning Number), and finishes any additional data input not established by an electronic chain of custody record.
Screening represents an initial swift analysis for illicit drugs. Although Screening is a budget-friendly option to exclude drug presence in most samples, a positive outcome necessitates further verification to be valid in legal proceedings. Samples that test presumptive positive in Screening require additional confirmation.
If Screening results in a presumptive positive, more hair is detached from the primary sample and prepped for Extraction. At this stage, drugs are isolated from hair at concentrations far lower than those in alternate techniques (e.g., urine or oral fluid), making hair analysis a challenging procedure to execute.
To confirm a positive screening outcome, GC/MS, GC/MS/MS, or LC/MS/MS is employed. All presumptive positive samples undergo cleansing before confirmation as appropriate. Each step from Accessioning through Confirmation conforms to the College of American Pathologists (CAP) Hair criteria and ISO / IEC 17025 accreditation.
