Hair Follicle Drug Testing - Creswell, NC

What it is, How it works

Hair analysis has emerged as an effective approach for identifying drug and alcohol consumption. Hair offers a long-term record of alcohol and drug use by entrapping biomarkers within the strands' fibers. When collected near the scalp, hair can serve as evidence of alcohol and drug usage for an estimated three-month timeframe. Collecting hair is straightforward, somewhat resistant to adulteration, and easily transportable.

A sample consisting of 200 hair strands measuring 1.5 inches (approximately the thickness of a #2 pencil) nearest to the scalp provides 100mg, which is the suitable quantity for both screening and confirmation. For EtG, add-ons, and tests exceeding 10 panels, 150mg is advised. Using a jeweler’s scale is suggested for measuring the sample. In the absence of scalp hair, an equal quantity of body hair may suffice. "Head hair" is exclusively in reference to scalp hair. "Body hair" pertains to all other types (such as facial and axillary).

Process Overview

The four predominant phases in lab processing of drug test results include Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial integration of a specimen into a lab’s system. Activities include ensuring proper sealing and shipping of the sample, assigning a unique LAN (Laboratory Accessioning Number), and fulfilling any data entry needs absent from an electronic chain of custody approach.

Screening entails a preliminary assessment for drug abuse. While screening offers an economical method to eliminate drug consumption in most cases, a positive result necessitates confirmation to stand in legal proceedings. Samples initially testing positive undergo further confirmation.

Should a sample test presumptively positive during Screening, additional hair from the original collection is prepared for Extraction. In this phase, hair undergoes extraction for drugs at lower concentrations compared to other procedures (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.

Verification of any positive screening outcome utilizes GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive undergo necessary washing prior to confirmation. Comprehensive laboratory procedures from Accessioning to Confirmation adhere to both CAP (College of American Pathologists) Hair qualifications and ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug use for up to 90 days, as opposed to urine tests' shorter detection span.
• Resistance to tampering: Hair drug tests are challenging to deceive, resulting in more reliable outcomes.
• Historical consumption patterns: These tests reveal usage trends over time, not just recent consumption.

Limitations:

• Inability to detect recent consumption: A period of 5-7 days is necessary for drugs to be detectable in hair.
• Expense: Hair drug tests often incur higher costs compared to other testing methods.
• Result variances: Results may fluctuate based on hair color and individual hair growth differences affecting drug metabolite concentration.

Note: Referred to frequently as "hair follicle tests", the analysis targets the hair strand, not the sub-scalp hair follicle.

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. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.
