Recognized as an effective method, hair testing plays a crucial role in identifying drug and alcohol consumption. It offers an extended perspective on drug and alcohol habits by capturing biomarkers within the strands of hair as they grow. With collection near the scalp, hair offers an estimated 3-month detection timeline for substances. Hair collection is straightforward, challenging to tamper with, and convenient for shipping.
Collecting a 1.5-inch segment of approximately 200 hair strands (around the thickness of a #2 pencil) from nearest the scalp yields 100mg of hair, which is ideal for analysis. For EtG, supplementary tests, and assessments surpassing 10 panels, a 150mg sample is preferred. Using a jeweler’s scale for specimen weighing is advisable. If scalp hair is inaccessible, collecting a similar quantity of body hair is an option. References to head hair imply scalp hair exclusively, while body hair encompasses other types (facial, axillary, etc.).
Process Overview
The procedure for processing a drug test in the laboratory encompasses four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning covers the preliminary handling of a specimen upon its entry into the lab system. This phase ensures the specimen was properly sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and addresses any supplemental data entry required by an electronic chain of custody system.
Screening consists of a preliminary assessment for substance abuse. Although cost-effective for ruling out drug usage in most cases, positive screenings require validation to be court-admissible. Samples that test positive in Screening necessitate a follow-up confirmation.
Should a sample test positive in the Screening stage, additional hair from the initial sample is readied for Extraction. This phase involves removing drugs from hair at a lower concentration than other methods (e.g., urine or oral fluid), underscoring the complexity of hair drug analysis.
Verification of positive screening outcomes is conducted using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples undergo necessary pre-confirmation washing. The complete laboratory operation, from Accessioning to Confirmation, adheres to the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 criteria.
Advantages of hair drug testing:
Limitations:
Note: Although often termed "hair follicle tests", the examination assesses the hair strand itself, not the follicle beneath the scalp.
