Hair analysis has emerged as an effective instrument for identifying drug and alcohol consumption. Hair captures a prolonged trace of alcohol and drugs by embedding biomarkers within the fibers of the hair as it develops. When taken from near the scalp, hair can offer a detection timeframe of up to roughly 90 days for alcohol and drugs. Hair is straightforward to collect, relatively hard to tamper with, and simple to transport.
A hair sample of 1.5 inches consisting of approximately 200 strands (roughly the thickness of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal amount for evaluation and validation. For EtG, additional tests, and/or panels beyond 10, a 150mg sample is advisable. It is suggested to weigh the sample via a jeweler’s scale. In case scalp hair is not obtainable, a comparable amount of body hair may be gathered. By head hair, we refer exclusively to scalp hair; body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The process of laboratory examination of a drug test includes Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the preliminary handling of a sample in a laboratory’s database. This comprises confirming the sample's sealed condition, proper shipping, assigning a unique LAN (Laboratory Accessioning Number), and completing any supplemental data entry absent from an electronic chain of custody system.
Screening consists of an initial rapid assessment for drugs of abuse. Although Screening is an economical means to exclude drug usage from most samples, any positive result necessitates verification to be legally valid. Samples yielding presumptive positive results during Screening necessitate further confirmation.
When a sample shows presumptive positivity during Screening, additional hair is extracted from the original sample for Extraction. In this phase, drugs are isolated from hair at much lower concentrations than other approaches (e.g., urine or oral fluid), making hair drug screening the most challenging methodology to execute.
Each positive screening outcome is verified via GC/MS, GC/MS/MS, or LC/MS/MS. Presumed positive samples undergo a washing process before confirmation if required. The entire laboratory flow from Accessioning to Confirmation undergoes assessment against the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 accreditation standards.
