Hair Follicle Drug Testing - Ardencroft, DE

What it is, How it works

Regarded as a robust mechanism, hair testing is used to identify drug and alcohol consumption. Hair strands encapsulate a prolonged history of substance intake by embedding biomarkers within the growing hair's fibers. When obtained near the scalp, hair testing offers a detection timeline extending up to 3 months for alcohol and other substances. Hair collection is straightforward, moderately challenging to tamper with, and convenient for shipping.

To acquire an optimal sample for analysis and verification, gather a 1.5-inch segment containing roughly 200 strands of hair (approximately the girth of a #2 pencil) nearest to the scalp, which equates to 100mg. For EtG, additional tests, and executions beyond 10 panels, a 150mg sample is advisable. Utilizing a jeweler’s scale to ascertain the specimen's weight is recommended. If scalp hair cannot be collected, an equal quantity of body hair is permissible. The term "head hair" exclusively pertains to scalp hair. Conversely, "body hair" encompasses all other hair varieties (facial, axillary, etc.).

Process Overview

There are four primary phases in the laboratory processing of drug test results: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample is assimilated into the laboratory's framework. This process checks that the sample was properly sealed and transported, assigns a LAN (Laboratory Accessioning Number) randomly, and completes any pending data entry absent from the electronic chain of custody system.

Screening serves as an initial rapid assessment for substance abuse. While Screening is an economical method to eliminate drug use for most samples, a positive result demands further verification for legal validity. Samples testing presumptively positive in Screening necessitate a confirmatory evaluation.

Should a sample yield a presumptive positive at the Screening stage, additional hair is extracted from the initial sample for the Extraction process. This phase involves isolating drugs from hair at notably lower concentrations compared to other methods (e.g., urine or oral fluid), thus rendering hair drug screening exceptionally challenging to execute.

Subsequent to a positive Screening outcome, Confirmation is executed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Prior to Confirmation, all samples with presumptive positives are cleansed as necessary. The complete process, from Accessioning to Confirmation, is scrutinized according to both the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Prolonged detection period: Hair drug assessments discern substance use up to 90 days, unlike urine tests which offer a more limited detection period.
• Hard to manipulate: The complexity of deceiving a hair drug test enhances its result accuracy.
• Reveals past usage: It demonstrates a timeline of drug usage over a longer duration rather than merely recent consumption.

Limitations:

• Incapable of identifying recent use: Detection of drugs in hair requires approximately 5-7 days.
• Expense: Hair drug assessments are typically more costly compared to other testing techniques.
• Result variation: Elements like hair color and individual disparities in hair growth influence drug metabolite concentration in hair.

Note: Although frequently labeled as "hair follicle tests," this examination assesses the hair strand and not 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.
