Hair Follicle Drug Testing - Boyd, MN

What it is, How it works

Hair analysis has emerged as an effective means for identifying substance consumption. Hair captures a lengthy record of drugs and alcohol by embedding markers within the fibers of the hair as it grows. When collected close to the scalp, hair offers an alcohol and drug detection span of up to roughly three months. Hair is straightforward to collect, moderately resistant to tampering, and conveniently transportable.

A 1.5-inch hair sample consisting of about 200 strands (comparable to the width of a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal quantity for screening and verification. For EtG, supplementary tests, and tests exceeding 10 panels, 150mg of the sample is advised. We suggest measuring the sample weight with a jeweler’s scale. In the absence of scalp hair, a similar amount of body hair can be collected. By head hair, we refer specifically to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The laboratory analysis of a drug test encompasses Accessioning, Screening, Extraction, and Confirmation as the primary phases.

Accessioning pertains to the initial incorporation of a specimen into a laboratory’s framework. This involves checking the secure sealing and proper shipment of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any further data entry absent from an electronic chain of custody setup.

Screening executes a preliminary rapid test for substance abuse. While Screening serves as a cost-efficient method to dismiss substance usage for most samples, a positive screen requires confirmation for court admissibility. Samples with a presumptive positive result in Screening necessitate a follow-up confirmation.

If a sample shows a presumptive positive in the Screening phase, additional hair is extracted from the initial sample and readied for Extraction. During this phase, drugs are extracted from hair at concentrations more diluted than in other methods (such as urine or oral fluid), rendering hair drug screening a challenging method to execute.

Confirmation for any positive screening outcome is conducted via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results undergo cleaning before confirmation as necessary. The comprehensive lab procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 certification standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug evaluations can reveal substance use for up to 90 days, unlike urine evaluations, which have a shorter detection period.
• Low likelihood of deception: Neglecting the tampering of a hair drug test results in more precise outcomes.
• Offers historical insight: It can indicate drug usage trends over time, not only recent consumption.

Limitations:

• Incapable of recent usage detection: It requires about 5-7 days for drugs to appear in hair.
• Expense: Overall, hair drug evaluations cost more than other drug testing models.
• Result variability: The concentration of drug metabolites can be influenced by factors such as hair color and personal hair growth differences.

Note: Despite often being labeled "hair follicle tests," the assessment analyzes the hair shaft, 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. 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.
