Hair assays have emerged as a formidable instrument for spotting the consumption of substances and alcohol. With hair encapsulating biomarkers within the fibers of its growing strands, it offers an extended history of alcohol and drug use. If plucked from close to the scalp, hair can furnish an observation window of up to roughly 3 months for both alcohol and drugs. Its collection is straightforward, tampering is relatively challenging, and it offers convenient transport.
A 1.5-inch snippet of around 200 hair strands (comparable to the size of a #2 pencil) nearest to the scalp yields 100mg of hair—this is the perfect sample for both screening and validation. For tests like EtG, additional check-ups, and those beyond 10 panels, a 150mg specimen is recommended. We advocate for using a jeweler’s scale to weigh the sample. If scalp hair isn’t present, a similar quantity of body hair is a viable substitute. References to head hair specifically relate to scalp hair, while body hair includes other hair types (such as facial or axillary).
Process Overview
The quartet of principal phases in the lab handling of a drug test involves Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial integration of a sample into a lab’s database. This process checks if a sample was appropriately sealed and dispatched, allocates a random LAN (Laboratory Accessioning Number), and wraps up any additional non-digital data documentation.
Screening carries out a swift preliminary assessment for substances of abuse. While it's an economical means to exclude drug usages on most samples, a positive screening requires corroboration for judicial acceptability. Any samples tested preliminarily positive in Screening necessitate a secondary validation.
If the Screening reveals a presumptive positive result, further hair is sourced from the original sample for Extraction. In this phase, drugs are extracted from the hair at substantially diminished concentrations than other procedures (e.g., urine or oral fluid), reinforcing the challenge inherent in hair drug analysis.
Any positive findings in screening undergo verification through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptively positive samples necessitate a pre-confirmation wash. Every facet of the lab protocol, from Accessioning to Confirmation, is scrutinized per both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
