Hair Follicle Drug Testing - Autryville, NC

What it is, How it works

Hair testing is recognized as a potent method for detecting drug and alcohol consumption. Hair captures a prolonged history of alcohol and drugs by encasing biomarkers within the fibers of the hair as it grows. When taken near the scalp, hair can offer a detection window of up to roughly 3 months for alcohol and drugs. Hair collection is straightforward, relatively hard to tamper with, and simple to transport.

A sample measuring 1.5 inches in length, consisting of around 200 hair strands (about the thickness of a #2 pencil) nearest the scalp, yields 100mg of hair, which is the optimal sample size for analysis and confirmation. For EtG, additional analyses, and/or testing beyond 10 panels, a sample of 150mg is suggested. It's advisable to weigh the sample using a jeweler’s scale. If scalp hair is not available, a similar amount of body hair can be collected. When mentioning head hair, it exclusively pertains to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result comprises four principal stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the first step, involving integrating a sample into a laboratory’s workflow. This procedure ensures the sample is correctly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and completes any remaining data entry absent in an electronic chain of custody system.

Screening conducts an initial rapid assessment for drugs of concern. While Screening effectively excludes drug use for most samples, a positive screen must be substantiated for court acceptance. Samples with presumptively positive Screening tests need further confirmation.

If a sample has a presumptively positive result during Screening, additional hair is extracted from the initial specimen and readied for Extraction. This phase involves extracting drugs from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug screening procedures.

Confirmation for any positive screening outcomes is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed before Confirmation as necessary. The entire laboratory sequence from Accessioning to Confirmation is conducted under both the CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair analysis can identify drug use for up to 90 days, contrasting with urine tests that offer a shorter window.
• Higher integrity: Cheating a hair drug test is extremely challenging, enhancing result accuracy.
• Historical insight: It supplies a timeline of drug use over time, beyond just recent activity.

Limitations:

• Cannot identify recent usage: Drugs become detectable in hair approximately 5-7 days post-use.
• Expense: Hair drug tests typically cost more than other testing methods.
• Variable outcomes: Factors like hair color and individual hair growth differences can impact drug metabolite levels in hair.

Note: Commonly known as "hair follicle tests", the analysis targets the hair shaft rather than the follicle under the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing offers distinct advantages over traditional urine tests in Autryville, NC. Key benefits include superior detection accuracy, with hair tests capturing a wider window of drug usage, up to 90 days.

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. In this special issue of Drug Testing and Analysis, we aim to showcase the remarkable manuscripts presented at this significant event, shedding light on the latest research and highlighting the future directions in this field.
