Hair Follicle Drug Testing - Oak City, NC

What it is, How it works

Hair analysis has gained recognition as an effective means to detect substance and alcohol consumption. It offers a prolonged record of alcohol and drug use by encasing biomarkers in the strands of growing hair. When collected near the scalp, hair can offer a detection timeframe of up to about three months for substances and alcohol. It is straightforward to gather, relatively tough to tamper with, and convenient to transport.

A 1.5-inch sample consisting of approximately 200 hair strands (comparable to the size of a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal sample for both screening and verification. For EtG, additional assessments, and/or tests exceeding 10 panels, a specimen of 150mg is advisable. Utilizing a jeweler’s scale to measure the sample is suggested. In the absence of scalp hair, a comparable quantity of body hair can be collected. When mentioning head hair, we specifically refer to scalp hair. Body hair encompasses all other forms (facial, axillary, etc.).

Process Overview

The key stages in laboratory processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial incorporation of a sample into a laboratory’s framework. This process verifies that the sample was securely sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and completes any further data entries absent from an electronic chain of custody system.

Screening includes a preliminary rapid assessment for substance abuse. Although Screening is an economical method to exclude drug use on the majority of samples, a positive result requires confirmation for court acceptability. Any samples that test presumptively positive in Screening necessitate additional confirmation.

Should a sample be presumptively positive at the Screening phase, additional hair is extracted from the initial sample and prepped for Extraction. During this stage, substances are extracted from hair at significantly lower concentrations than in other methodologies (e.g., urine or oral fluid), making hair drug screening the most challenging methodology to conduct.

Confirmation for any positive screening outcome is undertaken through GC/MS, GC/MS/MS, or LC/MS/MS. All samples testing presumptively positive are cleansed prior to confirmation as needed. The complete laboratory procedure from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for a duration of up to 90 days, in contrast to urine tests which offer a briefer detection timeframe.
• Challenging to deceive: Manipulating a hair drug test is exceedingly difficult, ensuring more precise outcomes.
• Offers historical data: It presents a pattern of substance use over an interval, not merely recent consumption.

Limitations:

• Inability to sense recent consumption: Approximately 5-7 days are necessary for substances to become detectable in hair.
• Expense: Generally, hair drug tests cost more than other testing techniques.
• Result variability: Elements like hair color and individual discrepancies in hair growth can influence the concentration of drug metabolites in hair.

Note: While typically termed as "hair follicle tests", the procedure analyzes the hair strand itself, 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. 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.
