Hair Follicle Drug Testing - Sturgeon, MO

What it is, How it works

Hair analysis has gained recognition as an effective method for detecting substance use. Hair retains a chronological record of alcohol and drug exposure by incorporating biomarkers within the hair shaft's strands. When harvested near the scalp, hair offers an approximate 3-month timeframe for detecting alcohol and various drugs. It is straightforward to gather, relatively resistant to tampering, and simple to transport.

A 1.5-inch segment containing approximately 200 hair strands (comparable to a #2 pencil's size) nearest the scalp provides 100mg of hair, the preferred sample for both screening and validation. For EtG, add-ons, and panels beyond 10 tests, a sample weighing 150mg is advised. To ensure precision, the specimen should be weighed with a jeweler’s scale. In the absence of scalp hair, a comparable quantity of body hair may be utilized. ‘Head hair’ refers specifically to scalp hair, while ‘body hair’ includes all other hair categories (such as facial or axillary hair).

Process Overview

The laboratory processing of drug tests involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary processing stage of integrating a sample into a laboratory's framework. This stage involves confirming proper sealing and shipping of the sample, assigning a random Laboratory Accessioning Number (LAN), and inputting any supplementary data not already included by an electronic chain of custody system.

The Screening phase provides an initial rapid assessment for illegal drug presence. Although it is a cost-efficient method to exclude drug use in most samples, a positive screening necessitates further confirmation for legal proceedings. Samples that test positively during Screening require additional verification.

Should a sample test presumptively positive during Screening, additional hair from the original specimen is extracted for the Extraction stage. This phase isolates drugs from hair at significantly lower concentrations than other testing methods like urine or oral fluid, highlighting why hair drug screening is considered the most challenging method to execute.

Any positive findings from Screening are verified through techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are thoroughly cleansed before confirmation, as required. The entire process, from Accessioning to Confirmation, undergoes review in adherence to both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug tests offer detection of substance use for as long as 90 days, whereas urine tests have shorter detection periods.
• Increased accuracy: The difficulty in deceiving a hair drug test enhances result accuracy.
• History of substance use: This method reveals patterns of drug usage over time, not strictly recent consumption.

Limitations:

• Lack of recent use detection: It necessitates roughly 5-7 days for drugs to appear in hair.
• Expense: Hair drug tests tend to be pricier than alternative testing methods.
• Result variability: Aspects such as hair color and individual hair growth differences may influence the levels of drug metabolites in hair.

Note: Commonly termed "hair follicle tests", the test examines the hair shaft 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. 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. The pitfalls encountered when the exogenous/endogenous nature of a substance is questioned were presented and discussed. The special issue presents also manuscripts that delve into the ethical implications of drug testing in drug facilitated sexual assaults.

Clinical Applications of hair testing are witnessed by the insight on environmental tobacco smoke exposure, assessed by hair analysis in a population of students and the study of in utero-exposure to drugs of abuse through neonatal hair analysis. Exposure to drugs was also important in cases of child abuse/neglect, when the clinical purpose of hair testing merge with its forensic applications.

The legal framework surrounding hair testing and the achievement of guidelines to ensure fairness, accuracy, and confidentiality in drug testing practices have also been discussed,and the SoHT consensus on general hair testing and testing for drugs of abuse was presented at the meeting and published as a Letter to the Editor.
