Hair examinations have emerged as an effective mechanism for uncovering drug and alcohol consumption. Hair retains a prolonged historical record of alcohol and drugs by embedding biomarkers within the strands of hair as it grows. When collected near the scalp, hair can deliver a detection period of up to roughly three months for alcohol and various drugs. Hair is straightforward to collect, fairly hard to tamper with, and convenient to transport.
A hair sample of 1.5 inches containing roughly 200 strands (similar in thickness to a #2 pencil) located nearest to the scalp offers 100mg of hair, which is optimal for both preliminary and confirmatory testing. For EtG, additional tests, and/or panels exceeding 10, a sample of 150mg is suggested. We advise using a jeweler's scale to weigh the sample. If scalp hair is not an option, a similar quantity of body hair might be used. Head hair specifically refers to scalp hair. In contrast, body hair encompasses other hair varieties (such as facial or axillary).
Process Overview
The procedure for processing drug test outcomes in the lab includes four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning incorporates the initial integration of a sample into the laboratory’s framework. This step involves confirming that the sample was appropriately sealed and dispatched, assigning a unique LAN (Laboratory Accessioning Number), and executing any supplementary data entry that might be missing without an electronic chain of custody.
Screening serves as an initial rapid assessment for the presence of drugs of abuse. Though Screening offers a cost-efficient method to exclude drug usage in most samples, any positive findings necessitate validation to be admissible legally. Any samples flagged as presumptively positive during Screening must undergo a subsequent confirmation stage.
Should a sample get marked as presumptively positive during the Screening phase, additional hair is extracted from the original sample for the Extraction phase. During this phase, drugs are extracted from hair at a significantly lower concentration relative to alternative methodologies (e.g., urine or oral fluids), highlighting the complexity involved in hair drug testing.
Confirmation of any initial positive result is accomplished using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples identified as presumptively positive undergo a pre-confirmation wash if required. The entire lab procedure, from Accessioning through Confirmation, is subject to inspection under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 accreditation.
