Hair Follicle Drug Testing - Blackhorse, MD

What it is, How it works

Hair analysis has become recognized as an influential technique for identifying substance and alcohol intake. Hair encapsulates a comprehensive record of alcohol and drug consumption by preserving biomarkers within the strands of growing hair. When obtained near the scalp, hair can reveal up to a 90-day detection period for substances. Hair is uncomplicated to gather, moderately challenging to tamper with, and straightforward to transport.

A 1.5-inch portion of roughly 200 hair strands (approximately the width of a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal sample for both screening and confirmation. For EtG additions and/or tests exceeding 10 panels, a 150mg specimen is advisable. Using a jeweler’s scale to weigh the specimen is recommended. In the absence of scalp hair, an equivalent amount of body hair may be used. When mentioning head hair, we mean scalp hair exclusively. Body hair encompasses all other hair types (such as facial and axillary).

Process Summary

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

Accessioning is the preliminary process of logging a sample into a lab's system. This step includes confirming that the sample was sealed and transported correctly, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry not covered by an e-chain of custody system.

Screening consists of an initial, rapid assessment for drugs of abuse. While Screening is a cost-effective method to eliminate drug use in most samples, a positive result needs confirmation for legal admissibility. Samples presumptively positive in Screening require subsequent confirmation.

If a sample tests positive in the Screening phase, additional hair is extracted from the initial specimen for the Extraction stage. Here, drugs are isolated from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), thereby making hair drug screening a challenging methodology.

Confirmation for any positive Screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo a cleansing before confirmation as needed. The complete laboratory sequence from Accessioning to Confirmation is audited according to both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Benefits of hair drug analysis:

• Extended detection period: Hair drug analyses can identify substance use for up to 90 days, unlike urine analyses which have a briefer detection period.
• Challenging to falsify: Hair drug analysis is hard to deceive, enhancing result accuracy.
• Delivers historical data: It reveals a consumption pattern over time, not merely recent use.

Constraints:

• Incapable of detecting recent consumption: A period of approximately 5-7 days is required for drugs to manifest in hair.
• Expense: Hair drug analyses generally incur higher costs than other drug testing methods.
• Result variability: Elements like hair color and individual hair growth differences can alter the concentration of drug metabolites in hair.

Note: Commonly misnamed as "hair follicle analyses", the analysis targets the hair strand rather than 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.
