Hair Follicle Drug Testing - Grantsboro, NC

What it is, How it works

Hair analysis is increasingly recognized as an effective mechanism for identifying drug and alcohol consumption. Hair captures a prolonged record of alcohol and drug usage by embedding biomarkers within the fibers as the strand develops. Collected from near the scalp, hair provides about a 90-day detection span for alcohol and drugs. Additionally, hair collection is straightforward, challenging to tamper with, and easy to transport.

A 1.5-inch length comprising roughly 200 hair strands (comparable to the width of a #2 pencil) from the scalp yields 100mg of hair, which is the optimal amount for both screening and verification. For EtG, additional testing, or panels exceeding 10, a 150mg sample is advisable. It's recommended to measure the specimen's weight using a jeweler's scale. If scalp hair isn't accessible, an equivalent volume of body hair can be gathered. In our context, head hair refers exclusively to scalp hair. Body hair includes all other types (e.g., facial, axillary).

Process Overview

There are four primary phases in lab processing of a drug test result: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the first stage of integrating a sample into the lab environment. This step entails checking that the sample is properly sealed and transported, allocating a distinct LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry not facilitated by an electronic chain of custody system.

Screening conducts an initial rapid assessment for substances of abuse. While Screening offers a cost-efficient strategy to exclude drug use among most samples, a positive outcome requires confirmation for legal admissibility. All samples flagged as presumptively positive during Screening demand a follow-up verification.

If a sample is flagged during Screening, additional hair is extracted from the original sample and readied for Extraction. This involves retrieving drugs at lower concentrations than other methods (such as urine or oral fluids), contributing to hair drug testing being the most challenging methodology.

GC/MS, GC/MS/MS, or LC/MS/MS technologies validate any positive results. Before confirmation, all samples marked as presumptively positive undergo washing if necessary. The holistic process from Accessioning to Confirmation is evaluated following the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug tests identify drug use over a span of up to 90 days, compared to urine tests' shorter timeframes.
• Challenging to falsify: Hair drug tests are difficult to cheat, enhancing result accuracy.
• Offers historical insights: These tests provide a timeline of drug usage, beyond just recent use.

Limitations:

• Cannot identify recent consumption: Drugs require approximately 5-7 days to manifest in hair.
• Expense: Hair drug tests tend to be more costly than alternative testing techniques.
• Variability in results: Factors like hair color and individual hair growth differences can impact drug metabolite concentration in hair.

Note: Although often labeled as "hair follicle tests", the analysis focuses on 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. 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.
