Hair Follicle Drug Testing - Pleasant Green, MO

What it is, How it works

Hair analysis has emerged as a significant means for identifying substance use. Hair captures a long-term record of alcohol and drugs by encapsulating biomarkers in its strands. When sourced near the scalp, hair offers up to a three-month detection timeframe for substances. It is uncomplicated to collect, hard to tamper with, and simple to send.

A sample of 1.5 inches consisting of roughly 200 strands (similar to the width of a #2 pencil) closest to the scalp provides 100mg, an ideal amount for testing efficacy. For EtG and extensive tests beyond 10 panels, 150mg is advised. It's recommended to use a jeweler’s scale for weighing. If scalp hair isn't an option, an equivalent amount of body hair can suffice. References to head hair denote only scalp hair, while body hair includes all other types (e.g., facial, axillary).

Process Overview

The laboratory procedure for drug test analysis entails four key phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning marks the initial integration of a sample into the lab’s system. This step ensures the sample's secure sealing and shipment, assigns a unique LAN (Laboratory Accessioning Number), and includes any data entry omitted by an electronic chain of custody.

Screening serves as a preliminary evaluation for abused substances. Though cost-effective for ruling out drug use in most cases, a positive result from Screening demands confirmation to hold up in legal settings. Samples yielding presumptive positives in Screening necessitate secondary verification.

Presumptive positives lead to additional hair extraction from the initial sample for the Extraction phase. Here, drugs are extracted at lower concentrations than with other methods (e.g., urine or oral fluid), highlighting the challenge of hair drug screening.

GC/MS, GC/MS/MS, or LC/MS/MS are employed to affirm any positive screen outcomes. Presumptive positives undergo washing before confirmation if required. The entire laboratory workflow from Accessioning through Confirmation is audited by both the CAP (College of American Pathologists) Hair designation and compliance with ISO/IEC 17025.

Advantages of hair drug testing:

• Extended detection period: Hair testing detects drugs for up to 90 days, surpassing the shorter window of urine tests.
• Difficult to manipulate: Hair drug tests are challenging to deceive, enhancing result reliability.
• Archives usage history: It reveals patterns of substance use over time, rather than just recent activity.

Limitations:

• Inability to detect recent consumption: Detection in hair takes roughly 5-7 days post-use.
• Expense: Hair drug tests typically incur higher costs than alternative testing methods.
• Result variability: Factors like color and personal hair growth differences can influence drug metabolite levels in hair.

Note: Commonly termed "hair follicle tests", these assessments examine the hair strand itself rather than 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.

Forensic Applications and Interpretation: One of the vital objectives of hair testing is its application in forensic investigations and legal proceedings. The SoHT meeting in Verona emphasized the significance of rigorous interpretation of analytical results and the need for standardized protocols. Manuscripts in this section present advancements in forensic toxicology, and have explored the challenges posed by emerging designer drugs and strategies to combat their proliferation.
