Hair Follicle Drug Testing - Crescent City North, CA

What it is, How it works

Hair testing is now regarded as a potent instrument for identifying drug and alcohol consumption. Hair acts as a long-term record for alcohol and other substances by encapsulating biomarkers within the growing strand's fibers. When samples are taken close to the scalp, they can provide an approximate 3-month detection window for alcohol and drugs. Hair collection is straightforward, somewhat resistant to tampering, and easy to transport.

A 1.5-inch segment of approximately 200 hair strands (around the size of a #2 pencil) nearest to the scalp yields 100mg of hair, ideal for both screening and confirmation. For EtG, additional tests, and/or over 10-panel screens, 150mg is recommended. We advise using a jeweler’s scale to weigh the specimen. If scalp hair is not available, an equivalent amount of body hair may be used. Referring to head hair pertains solely to scalp hair, while body hair encompasses all other types (such as facial and axillary).

Process Overview

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

Accessioning begins with integrating a sample into a lab's system. This process includes verifying the correct sealing and shipment of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry missing from an electronic chain of custody system.

Screening serves as an initial, rapid assessment for drug use. While cost-efficient for ruling out drug usage in most samples, any positive screen must be confirmed for legal acceptability. Samples indicating presumptive positivity in Screening require secondary confirmation.

If Screening shows presumptive positivity, additional hair is retrieved from the original specimen for Extraction. In this stage, the drugs are extracted from hair at significantly lower concentrations compared to other methods (such as urine or oral fluid), which makes hair drug screening the most complex methodology.

GC/MS, GC/MS/MS, or LC/MS/MS techniques conduct the Confirmation of any positive screening. Presumptive positive samples undergo washing before confirmation if necessary. The entire lab process from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 standard accreditation.

Advantages of hair drug testing:

• Extensive detection period: Hair drug tests can identify drug use for up to 90 days, whereas urine tests present a shorter detection span.
• Hard to manipulate: Cheating a hair drug test is incredibly challenging, thus heightening result accuracy.
• Offers a chronological record: It provides a timeline of drug usage rather than just recent activity.

Limitations:

• Cannot identify recent usage: Drugs take about 5-7 days to become detectable in hair.
• Expense: Hair drug testing generally incurs higher costs than other testing methods.
• Outcome variability: Certain factors, like hair color and individual growth variations, can alter drug metabolite levels in hair.

Note: Although commonly called "hair follicle tests", these tests analyze the hair strand and not the scalp's hair follicle.

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.
