Hair Follicle Drug Testing - Castle Hayne, NC

What it is, How it works

Hair analysis is regarded as a robust method for identifying the usage of drugs and alcohol. By capturing biomarkers within the strands, hair offers an extended history of substance use. When acquired near the scalp, it can reveal substance usage over an estimated 90-day span. Hair is straightforward to gather, challenging to tamper with, and convenient to transport.

A sample measuring 1.5 inches comprising roughly 200 hair strands (approximating a #2 pencil in size) near the scalp yields 100mg of hair, which is the optimal quantity for evaluation. For EtG, special tests, and/or assessments exceeding 10 panels, 150mg is advised. Utilizing a jeweler’s scale for weighing is suggested. Should scalp hair be unavailable, an equivalent quantity of body hair can be used. Scalp hair refers solely to head hair, while body hair encompasses all other hair types (like facial or axillary).

Process Overview

The laboratory procedure for processing a drug test result involves Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the initial handling of a specimen within a laboratory’s framework. This step confirms the sample's proper sealing and shipment, allocates a random LAN (Laboratory Accessioning Number), and finalizes any needed data input absent in an electronic chain of custody form.

Screening offers a rapid preliminary evaluation for substance abuse. Although cost-efficient for eliminating drug use in most specimens, a positive result in Screening mandates further confirmation for legality in court. Samples with preliminary positive outcomes in Screening demand additional confirmation.

Positive indications in the Screening stage require further hair extraction from the specimen for processing in Extraction. Here, drugs are sourced at lower concentrations compared to other methods (like urine or oral fluids), illustrating why hair screening is a complex practice.

Verification of any positive Screening outcome is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicating potential positives are cleansed prior to confirmation if necessary. The entire laboratory operation from Accessioning to Confirmation is examined under CAP (College of American Pathologists) guidelines and accredited as per ISO / IEC 17025 norms.

Advantages of hair drug testing:

• Long detection window: Hair drug analysis identifies drug use up to 90 days, offering a wider time frame than urine tests.
• Difficulty to cheat: Manipulating a hair drug test is notably difficult, increasing result reliability.
• Provides historical data: A consistent use pattern can be identified, not just recent consumption.

Limitations:

• Cannot detect recent use: Detection of drugs in hair requires roughly 5-7 days post usage.
• Cost: Compared to other drug tests, hair examinations are generally pricier.
• Variations in results: Hair color and individual hair growth variances may alter drug metabolite levels.

Note: Despite being commonly called "hair follicle tests", the evaluation processes the hair strands, not the follicles 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.
