Hair evaluations are recognized as an effective method for detecting the use of drugs and alcohol. Hair encapsulates an extended timeline of consumption by ensnaring biomarkers in the fibers of the hair strand as it grows. To achieve up to about a 3-month detection timeframe for alcohol and other substances, hair should be collected directly adjacent to the scalp. Hair collection is straightforward, challenging to tamper with, and convenient to transport.
Obtaining a 1.5-inch segment of around 200 hair strands (comparable to a #2 pencil's thickness) nearest to the scalp yields 100mg of hair, which is the optimal sample size for analysis and verification. For EtG, additional panels, or tests exceeding 10 panels, a 150mg sample is suggested. Use a jeweler’s scale for accuracy when weighing the sample. If scalp hair cannot be sourced, a comparable volume of body hair can be used. When discussing head hair, we mean specifically scalp hair. Body hair encompasses all other hair variations (such as facial and axillary hair).
Process Overview
The laboratory processing of a drug test result consists of four principal stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial introduction of a sample into the laboratory system. This step includes verifying the sample's proper sealing and shipment, assigning a unique LAN (Laboratory Accessioning Number), and completing any requisite data entry not supplied by an electronic chain of custody system.
Screening carries out a preliminary rapid examination for illicit substances. Although Screening is an economical approach to exclude drug use for most samples, it requires confirmation to be accepted in legal proceedings. Samples that yield a presumptive positive in Screening necessitate a follow-up confirmation.
A presumptive positive result discovered during the Screening phase prompts further hair extraction from the original sample for the Extraction process. In this phase, drugs are isolated from hair at a notably lower concentration than other methods (like urine or oral fluid), making hair drug screening the most demanding method to execute.
Any positive result from screening goes through Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples are washed as necessary. The full laboratory process, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.
