Hair Follicle Drug Testing - Quinhagak, AK

What it is, How it works

Hair analysis has emerged as an effective approach for identifying substance and alcohol consumption. It captures a comprehensive timeline of alcohol and drug usage by embedding molecular indicators within the strands of hair. When samples are taken from near the scalp, hair analysis offers a detection range of up to roughly three months. Collection is straightforward, it's relatively challenging to tamper with, and transportation is hassle-free.

An ideal test sample involves gathering 1.5 inches of approximately 200 hairs (roughly the thickness of a #2 pencil) nearest to the scalp, amounting to 100mg — the preferred sample for initial testing and verification. For extended panels beyond 10 or including EtG, a collection of 150mg is advisable. It is suggested to weigh this on a jeweler’s scale. Should scalp hair be inaccessible, comparable quantities of body hair can be utilized. By "head hair," we mean scalp-specific hair. "Body hair" encompasses all other hair varieties (like facial or axillary).

Process Overview

The sequence of procedures in testing comprises Accessioning, Initial Examination, Extraction, and Verification.

Accessioning pertains to the sample's primary handling in a lab's system. It involves ensuring proper sealing and transportation, assigning a random LAN (Laboratory Accessioning Number), and filling in any missing information not recorded by an electronic custody chain system.

The Initial Examination is a preliminary assessment for drug presence. Although economical for excluding potential drug use for most samples, a positive indication requires official confirmation to serve in judicial matters. Any samples showing presumptive positive results must undergo secondary verification.

Any presumptively positive indication in Screening necessitates additional hair from the initial specimen for the Extraction phase. This involves separating drugs from hair at significantly lower concentrations compared to other methods (e.g., urine or saliva), making this kind of screening particularly demanding.

Verification of any positive indication in the Initial Examination is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples showing presumptive positive results are cleansed before verification as needed. The complete lab workflow, from Accessioning to Verification, adheres to CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 requirements.

Advantages of hair drug testing:

• Extended detection period: Unlike urine tests, hair tests can uncover drug use spanning up to three months.
• Hard to manipulate: The accuracy of hair tests is higher due to the difficulty of tampering.
• Insights into usage patterns: They offer insights into long-term usage instead of just recent activity.

Limitations:

• Delayed detection: Drugs typically take 5-7 days to become traceable in hair.
• Expense: Hair tests usually incur higher costs than other testing types.
• Inconsistency in outcomes: Elements such as hair pigmentation and growth differences can impact drug concentration levels.

Note: Although termed "hair follicle tests", the actual analysis targets the hair strand, avoiding 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.
