Hair analysis has emerged as a robust method for identifying drug and alcohol consumption. Hair retains a historical record of alcohol and other substances by capturing biomarkers within the fibers of its growing strands. When sourced close to the scalp, hair can offer an approximate 3-month detection period for alcohol and drugs. It is easy to gather, fairly resistant to tampering, and straightforward to transport.
A 1.5-inch segment of about 200 hair strands (roughly the thickness of a #2 pencil) nearest to the scalp will yield 100mg of hair, the optimal amount for both testing and confirmation. For EtG additions and/or analyses exceeding 10 panels, a 150mg sample is ideal. We suggest using a jeweler’s scale for specimen weighing. If scalp hair is unavailable, a comparable quantity of body hair can be used. When discussing head hair, we exclusively mean scalp hair, while body hair refers to all other types (such as facial, axillary, etc.).
Process Overview
The principal steps in laboratory processing of drug test outcomes are Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary integration of a sample into a lab’s system. This process verifies the sample’s proper sealing and shipment, allocates a random LAN (Laboratory Accessioning Number), and completes any extra data entry not covered by an electronic chain of custody regimen.
Screening offers an initial, swift assessment for drugs of abuse. Although it’s a cost-efficient approach for negating drug use in most samples, a positive Screening result must be confirmed for legal admissibility. Samples testing presumptively positive in Screening need a secondary confirmation.
If a sample tests presumptively positive during Screening, additional hair is extracted from the initial sample and prepared for Extraction. Here, drugs are extracted from hair at lower concentrations compared to other approaches (such as urine or oral specimens), highlighting the complexity of hair drug analysis.
Confirmation of any positive screening outcome is performed through GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples are washed if necessary. The entire lab process, from Accessioning to Confirmation, is inspected under the CAP (College of American Pathologists) Hair specification and ISO / IEC 17025 standard accreditation.
