Hair Follicle Drug Testing - Bishop, CA

What it is, How it works

Hair testing is widely regarded as a robust method for detecting the use of alcohol and drugs. By capturing biomarkers within the fibers as hair grows, it provides a long-term record of alcohol and drug use. Hair samples collected close to the scalp can offer detection windows of up to three months for alcohol and drugs. This method is easy to perform, difficult to adulterate, and simple to transport.

Taking a 1.5-inch sample containing around 200 strands nearest to the scalp yields 100mg of hair, which is ideal for both screening and confirmation. For tests like EtG and those exceeding 10 panels, 150mg is advised. Utilizing a jeweler’s scale for specimen measurement is suggested. If scalp hair is unavailable, an equivalent amount of body hair can be used. When mentioning head hair, it specifically denotes scalp hair. Body hair includes all other types (such as facial and axillary hair).

Process Overview

The laboratory process for a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step where a sample is processed into the laboratory’s system. This ensures the sample is sealed and shipped correctly, assigns a random LAN (Laboratory Accessioning Number), and completes any necessary additional data entry that an electronic chain of custody system might not cover.

In Screening, an initial rapid check for drugs of abuse is performed. While it is a cost-effective method to eliminate drug use in most samples, a positive screen requires confirmation to be court-admissible. Samples with presumptive positive results in Screening need secondary confirmation.

For presumptive positives in the Screening phase, additional hair is taken from the original sample and prepared for Extraction. Here, drugs are identified at lower concentrations in hair compared to other methods like urine or oral fluid, highlighting the complexity of hair drug screening.

Confirmation for any positive screening result is achieved via GC/MS, GC/MS/MS, or LC/MS/MS. Needed presumptive positive samples are washed before confirmation. The entire laboratory procedure, from Accessioning to Confirmation, is scrutinized according to CAP (College of American Pathologists) Hair designation and the ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use up to 90 days, unlike urine tests with shorter detection spans.
• Hard to manipulate: Cheating a hair drug test is challenging, ensuring higher accuracy.
• Historical patterns: It reveals drug use patterns over time, not just recent consumption.

Limitations:

• Inability to detect recent usage: Drugs become detectable in hair approximately 5-7 days after use.
• Expense: Hair drug tests tend to be costlier compared to other drug testing methods.
• Result variability: Variables such as hair color and individual growth rates can impact drug metabolite concentrations in hair.

Note: The term "hair follicle tests" is often used, but the test actually examines 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.
