Hair Follicle Drug Testing - Mcgrady, NC

What it is, How it works

Hair analysis is recognized as an effective method for detecting alcohol and drug consumption. By integrating biomarkers within the strands, hair reveals a comprehensive history of substance use. When sampled near the scalp, hair offers a detection timeline extending up to three months for substances. The collection process is straightforward, with minimal risk of tampering, and facilitates easy transportation.

A 1.5-inch segment containing around 200 hair strands (resembling a #2 pencil's thickness) near the scalp provides 100mg, which suffices for both screening and confirmation tests. For EtG, additional tests, or any screening over 10 panels, a specimen weighing 150mg is advisable. Utilizing a jeweler's scale to weigh the sample is suggested. Should scalp hair be absent, a comparable volume of body hair is viable. Note that head hair refers solely to scalp strands, whereas body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The laboratory procedures for processing drug test results encompass four essential phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning starts with integrating a sample into a laboratory's records. This phase includes ensuring the sample's seal and proper shipping, issuing a random LAN (Laboratory Accessioning Number), and finalizing any outstanding data input absent from an electronic chain of custody system.

Screening conducts an initial, rapid assessment for common drugs of abuse. Although cost-effective for most samples, a positive screen requires substantiation before being legally permissible. Samples yielding a tentative positive in Screening necessitate subsequent confirmation.

Samples indicated as positive during Screening prompt additional hair collection from the initial sample for Extraction. During this phase, drugs are extracted at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), underscoring hair drug screening's complexity.

Positive screening outcomes mandate confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all samples testing positive provisionally are cleansed as needed. The progression from Accessioning to Confirmation is audited against both the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditations.

Advantages of hair drug testing:

• Extended detection span: Hair drug testing reveals up to 90 days of drug use, unlike urine tests which have a more limited window.
• Enhanced accuracy: The difficulty in manipulating hair test results contributes to their reliability.
• Chronological usage pattern: Offers insights into drug consumption over time, beyond immediate use.

Limitations:

• No detection of recent usage: Drug presence in hair becomes apparent only after 5-7 days.
• Higher costs: Typically, hair drug tests are pricier than alternative testing approaches.
• Result variability: Attributes like hair color and growth rate variation can influence drug metabolite levels in hair.

Note: Commonly termed "hair follicle tests", this test scrutinizes 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.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis. The impact of hair treatments on the oxidation/decomposition of drugs in hair was also explored, as the long-term fate of drugs incorporated in the keratin matrix.
