Utilizing hair testing is increasingly acknowledged as an effective means for detecting substance and alcohol consumption. Hair captures a detailed history of alcohol and other drug use by embedding biomarkers within the hair shaft as it grows. When sampled near the scalp, hair offers roughly a three-month retrospective window for identifying alcohol and drug consumption. The collection process for hair is straightforward, moderately challenging to tamper with, and convenient to send.
An ideal specimen involves a 1.5-inch segment of around 200 hair strands (comparable in diameter to a #2 pencil) closest to the scalp, providing 100mg needed for proper screening and confirmation. For EtG, additional tests, and those exceeding 10 panels, a sample of 150mg is optimal. The specimen should be weighed using a jeweler's scale. In the absence of scalp hair, an equivalent volume of body hair is acceptable. Here, "head hair" specifically denotes scalp hair, while "body hair" encompasses all other hair types (such as facial and axillary).
Process Overview
The key phases in laboratory processing of drug test results include Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample enters the lab’s workflow, ensuring it was properly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any pending data input not covered by an electronic chain of custody system.
Screening involves a preliminary assessment for substances of abuse. While an economical method to exclude drug use in most samples, a positive outcome must be verified to be court-worthy. Samples that indicate a preliminary positive in Screening necessitate a follow-up confirmation.
When a sample demonstrates a presumptive positive during Screening, additional hair is sourced from the original specimen for Extraction. Here, substances are extracted at significantly lower concentrations than in alternatives like urine or oral fluid testing, underscoring the complexity of hair drug screening.
Confirmation of any promising screening outcomes is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation if needed. The complete lab procedure from Accessioning to Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair classification and accreditation per ISO / IEC 17025 criteria.
