Hair Follicle Drug Testing - Fort Dick, CA

What it is, How it works

Hair analysis is now recognized as an effective technique for identifying drug and alcohol consumption. By locking away biomarkers in the strands as hair matures, it provides an extensive record of substances and alcohol use. When sampled near the scalp, it offers a detection period extending up to roughly 90 days for substances and alcohol. The collection of hair is straightforward, challenging to tamper with, and uncomplicated to transport.

Gathering a 1.5-inch lock of approximately 200 hairs (similar in size to a #2 pencil) nearest the scalp results in 100mg of hair, ideal for initial screening and validation. For EtG assessments, additional tests, and those exceeding 10 panels, 150mg is advised. It's recommended to measure the sample using a jeweler’s scale. In the absence of head hair, a comparable quantity of body hair may suffice. By head hair, we specifically mean scalp hair, while body hair applies to all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of drug test results involves four critical stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning addresses the initial treatment of a sample within a lab’s framework. This encompasses ensuring the sample's proper sealing and delivery, allocating a unique LAN (Laboratory Accessioning Number), and finishing any supplementary data input absent from an electronic custody chain.

Screening entails a preliminary swift scanning for substance abuse. While a cost-saving method to negate substance use in most samples, any positive indication in Screening must undergo corroboration to stand up in court. Presumptively positive samples in Screening indeed need further confirmation.

For samples flagged as presumptively positive in Screening, additional hair is extracted from the original sample for Extraction preparation. In this phase, substances are isolated from hair at concentrations substantially lower than other methods (e.g., urine or oral fluids), which explains why hair drug analysis is considered the most intricate methodology to execute.

Any positive indication from the screening is confirmed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples undergo washing if necessary before confirmation. The full laboratory sequence from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Prolonged detection span: Hair drug analyses can reveal drug usage up to 90 days, whereas urine analyses offer a shorter detection period.
• Cheating is hardly possible: Cheating a hair drug analysis is extremely challenging, thus providing more reliable results.
• Historical insights: It offers a comprehensive drug use pattern, not merely a snapshot of recent usage.

Limitations:

• Unable to identify recent usage: A span of about 5-7 days is required for drugs to appear in hair tests.
• Expense: Hair drug analyses typically cost more compared to other drug testing alternatives.
• Result variability: Elements such as hair color and individual growth rates can influence drug metabolite concentrations in hair.

Note: Although often called "hair follicle tests," assessments target the hair strand, 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.

In conclusion, the special issue of Drug Testing and Analysis, featuring manuscripts from the SoHT–GTFI meeting in Verona 2022, reflects the remarkable advancements achieved in this field.
