Hair Follicle Drug Testing - Lindseyville, KY

What it is, How it works

Hair assessments have emerged as a robust means for identifying drug and alcohol consumption. Hair strands offer an extensive timeline of substance use by embedding biomarkers within the hair fibers as they grow. When taken near the scalp, hair can reveal drug and alcohol presence over a roughly 3-month span. The collection of hair is straightforward, challenging to tamper with, and convenient to transport.

A 1.5-inch batch involving about 200 hair strands (approximately the width of a #2 pencil) from the scalp provides 100mg of hair, which is the optimal volume for analysis and validation. For EtG examinations, add-ons, or tests exceeding 10 panels, a 150mg sample is advisable. We suggest measuring the sample using a jeweler's scale. If hair from the scalp is unavailable, a comparable quantity of body hair can be taken. When we mention head hair, we are specifically talking about scalp hair. Body hair pertains to other hair types (face, underarm, etc.).

Process Overview

The four primary phases in laboratory processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning covers the initial handling of a sample within a laboratory's framework. This step entails checking the proper sealing and transport of the sample, assigning a LAN (Laboratory Accessioning Number) randomly, and performing any additional data entry not available through an electronic chain of custody system.

Screening offers a preliminary rapid assessment for drugs. While Screening is affordable for excluding drug use in most samples, a positive result necessitates confirmation to be admissible in legal contexts. Any samples that are presumptively positive in Screening need further confirmation.

If a sample returns a presumptively positive result in the Screening phase, additional hair is drawn from the original sample and subjected to Extraction. In this phase, drugs are extracted from hair at much lower concentrations compared to other techniques (e.g., urine or saliva), which makes hair drug testing particularly challenging.

Confirmation of any positive screening result is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed prior to confirmation as required. The entire lab procedure from Accessioning to Confirmation is critically evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection window: Hair drug testing can identify drug use for up to 90 days, unlike urine tests which offer a shorter detection timeline.
• Hard to manipulate: Hair drug testing is difficult to cheat, ensuring more precise results.
• Offers historical insight: It provides a chronological pattern of drug usage over time, rather than just recent use.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair after roughly 5-7 days.
• Expense: Hair drug testing tends to be pricier than other drug testing methods.
• Result variability: Elements such as hair color and individual hair growth differences may influence drug metabolite levels in the hair.

Note: Although commonly called "hair follicle tests", the analysis evaluates the strand 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.
