Recognized as a robust method for identifying drug and alcohol consumption, hair testing uses advancing hair strands to capture biomarkers, offering an extended overview of substance usage. Collection near the scalp allows hair to reveal up to a three-month detection period for alcohol and other drugs. Its collection is straightforward, alterations are challenging, and it is easily shippable.
A sample measuring 1.5 inches and consisting of roughly 200 hair strands (comparable to the width of a #2 pencil) nearest to the scalp delivers 100mg, the optimal amount for both screening and verification. For tests such as EtG, additions, or those surpassing 10 panels, 150mg is advisable. It's recommended to assess the sample weight using a jeweler’s scale. In the absence of scalp hair, a corresponding quantity of body hair can be gathered. "Head hair" strictly signifies scalp hair, while "body hair" encompasses all other varieties (such as facial, axillary, etc.).
Process Overview
The laboratory examination of a drug test sample encompasses four key phases: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a specimen undergoes initial handling in a lab’s system. This process includes confirming that it was sealed and dispatched correctly, generating a random Laboratory Accessioning Number (LAN), and completing any additional data input absent in an electronic record of custody system.
Screening consists of a preliminary assessment for illicit substances. While Screening is a cost-efficient approach to exclude drug usage for most specimens, any positive result necessitates confirmation to hold in legal situations. Samples showing a preliminary positive result in Screening undergo further confirmation.
In instances of a presumptively positive Screening, additional hair is extracted from the primary sample for Extraction. In this phase, substances are retrieved from hair at significantly reduced concentration levels than with other approaches (such as urine or oral fluid), highlighting the challenges of executing hair drug screening.
Confirming any positive Screening result involves GC/MS, GC/MS/MS, or LC/MS/MS techniques. Every sample with a presumptive positive result is cleansed ahead of confirmation as required. The entire progression from Accessioning to Confirmation is scrutinized in accordance with the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
