Hair Follicle Drug Testing - Kenvir, KY

What it is, How it works

Utilizing hair testing has become recognized as an efficient method for identifying substance and alcohol use. Hair offers an extended retrospective of alcohol and drug consumption by embedding biomarkers within the growing hair's fibers. When sampled near the scalp, hair can provide a detection time frame of up to around 3 months for alcohol and narcotics. Hair collection is straightforward, relatively hard to tamper with, and simple to transport.

A 1.5-inch hair specimen, comprising approximately 200 strands (similar in thickness to a #2 pencil), nearest to the scalp, yields 100mg, which is the optimal quantity for evaluation and validation. For EtG outputs, supplementary assessments, and/or analyses exceeding 10 panels, a sample size of 150mg is advisable. We suggest using a jeweler’s scale for weighing the sample. If head hair is not accessible, a proportionate amount of body hair may be substituted. In our context, head hair pertains solely to scalp hair. Body hair encompasses all other types (facial, underarm, etc.).

Process Overview

The key phases in processing a drug test report in the laboratory comprise Accessioning, Screening, Extraction, and Confirmation.

Accessioning is concerned with the preliminary processing of a sample within a laboratory setup. It includes ensuring the sample was properly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any further data input that an electronic chain of custody system does not cover.

Screening embodies an initial swift assessment for drugs of abuse. While serving as a cost-effective strategy to preclude drug usage on most samples, a positive screening outcome must be validated for court admissibility. Samples that are initially positive during Screening necessitate a subsequent confirmation.

For samples initially positive during the Screening stage, additional hair is retrieved from the initial sample for the Extraction process. At this stage, drug extraction from hair occurs at a significantly lower concentration compared to other methods (e.g., urine or oral fluid), hence making hair drug analysis the most demanding technique.

Positive screening results are confirmed via GC/MS, GC/MS/MS, or LC/MS/MS methods. All presumptive positive samples undergo washing before confirmation, as required. The entire process from Accessioning to Confirmation is reviewed under the CAP (College of American Pathologists) Hair designation along with the accreditation of ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use extending up to 90 days, unlike urine tests which offer a shorter detection period.
• Hard to manipulate results: Cheating on a hair drug test is highly challenging, thereby providing more reliable results.
• Delivers historical insight: These tests offer a trajectory of substance use over time, beyond just recent consumption.

Limitations:

• Does not identify recent usage: It takes about 5-7 days before drugs become evident in hair.
• Expense: Hair drug assessments usually cost more compared to alternative testing methods.
• Result variability: Factors like hair color and individual hair growth differences can impact drug metabolite levels in hair.

Note: Although commonly called "hair follicle tests", the test analyzes the hair strand rather than the hair follicle under 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.
