Hair analysis is now recognized as an effective means for identifying the consumption of drugs and alcohol. It captures a comprehensive timeline of substance use by embedding biomarkers within the strands of growing hair. When clipped near the scalp, hair can showcase a detection period of up to roughly 90 days for drugs and alcohol. It's easy to collect, hard to tamper with, and convenient to transport.
A section measuring 1.5 inches consisting of roughly 200 hair strands (comparable to the thickness of a #2 pencil) close to the scalp yields 100mg, optimal for screening and verification. For EtG, additional tests, and/or panels exceeding 10, a 150mg sample is advised. We advocate using a jeweler’s scale for accuracy. Should scalp hair be unavailable, a comparable quantity of body hair may be used. References to head hair pertain strictly to scalp hair, while body hair encompasses all other types (facial, underarm, etc.).
Process Overview
The drug testing laboratory process comprises four essential steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning introduces a sample into a lab's framework. This step confirms the sample was correctly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and finalizes any outstanding data entry absent from an electronic chain of custody system.
Screening involves a preliminary swift assessment for drug abuse. It is an economical method to dismiss drug usage in most samples; however, a positive screening must be corroborated before being court-admissible. Samples suspected to be positive require additional confirmation.
Should a sample be suspected of being positive in the Screening phase, additional hair is taken from the original specimen for the Extraction process. Here, drugs are separated from hair at much reduced concentrations than other tests (such as urine or oral fluid), explaining the complexity of hair drug screening.
Verification of any presumed positive screening result occurs via GC/MS, GC/MS/MS, or LC/MS/MS. All samples suspected to be positive are cleansed before confirmation as necessary. Every step from Accessioning to Confirmation is assessed under the CAP (College of American Pathologists) Hair designation and adheres to ISO/IEC 17025 accreditation standards.
