Hair Follicle Drug Testing - Glenvar, VA

What it is, How it works

Hair analysis has emerged as a robust method for identifying drug and alcohol consumption. The hair captures long-term evidence of such substances by embedding markers within its fibers as it grows. When collected near the scalp, hair can reveal a detection period of up to around three months for drugs and alcohol. The collection of hair is straightforward, moderately resistant to tampering, and simple to transport.

A 1.5-inch segment comprising approximately 200 hair strands (comparable to the thickness of a #2 pencil) closest to the scalp will yield 100mg of hair, the optimal sample size for both screening and confirmation. For performing EtG testing, additional tests, or tests exceeding 10 panels, a specimen of 150mg is advisable. We suggest using a jeweler’s scale for accurate specimen measurement. If scalp hair is not accessible, a similar quantity of body hair can be utilized. When mentioning head hair, it specifically refers to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The lab processing for a drug test outcome comprises four major phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary step of integrating a sample into a laboratory's system. It ensures the sample's seal and shipment integrity, assigns a unique LAN (Laboratory Accessioning Number), and finishes any additional entries not covered by an electronic chain of custody system.

Screening entails an initial rapid assessment for drug abuse. Although Screening is economical for excluding drug use in most cases, a positive outcome mandates confirmation for legal acceptability. All samples that test positive in Screening necessitate further confirmation.

When a sample tests positive during Screening, additional hair is drawn from the original specimen and readied for Extraction. This phase involves extracting drugs from hair at significantly lower concentrations than in alternative methods (such as urine or oral fluid), underscoring the complexity of conducting hair drug screenings.

Positive Screening results undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples are cleansed as required. The complete lab procedure, from Accessioning through to Confirmation, is thoroughly reviewed under the CAP (College of American Pathologists) Hair designation and accreditation compliant with ISO/IEC 17025 standards.

Benefits of hair drug testing:

• Extended detection window: Hair drug tests can trace drug use for up to 90 days, unlike urine tests which have a briefer window.
• Challenging to falsify: Hair drug tests are very hard to deceive, thus making the outcomes more reliable.
• Delivers historical insights: It provides a timeline of drug use over time, not solely recent usage.

Drawbacks:

• Inability to detect recent usage: It usually takes 5-7 days for drugs to manifest in hair.
• Expense: Hair drug tests tend to be costlier compared to other drug testing methods.
• Result variability: Elements like hair color and personal differences in hair growth can alter drug metabolite concentration in hair.

Note: Although commonly called "hair follicle tests", the test itself examines the hair strand rather than the follicle beneath the scalp.

What's New In Hair Follicle Drug Testing according to the Hair Drug Testing Experts

With its multidisciplinary nature, hair testing brings together researchers, scientists, and experts from various domains to develop innovative techniques, explore new methodologies, and address emerging concerns, responding to the ever-evolving challenges of drug abuse, therapeutic drug monitoring, and environmental exposures to pollutants.

The joint meeting of the Society of Hair Testing (SoHT) and the Italian Group of Forensic Toxicologists (GTFI) was organized in Verona, June 8–10, 2022, and hosted by the Legal Medicine team of the Verona University Hospital, directed by Franco Tagliaro together with Federica Bortolotti and Rossella Gottardo.

It served as a prominent platform for knowledge exchange and collaboration, facilitating groundbreaking advancements in hair testing and analysis.
