Hair Follicle Drug Testing - Phoenixville, PA

What it is, How it works

Hair tests have emerged as an effective method in detecting substance use. Hair offers an extended timeline of alcohol and drug use by embedding biomarkers within the fibers as the hair grows. If collected near the scalp, it can reveal information for about a 3-month period for both alcohol and other substances. Collection of hair is straightforward, somewhat resistant to tampering, and convenient for transportation.

A sample measuring 1.5 inches with roughly 200 hair strands (similar in size to a #2 pencil) near the scalp provides about 100mg of hair, which is the optimal amount for analysis and validation. For EtG, additional options, and tests exceeding 10 panels, 150mg of the sample is advised. We suggest using a jeweler’s scale for weighing the sample. In the absence of scalp hair, an equivalent volume of body hair can be used. When we mention head hair, it pertains strictly to scalp hair. Body hair encompasses all other hair types (facial, armpits, etc.).

Procedure Summary

The key stages in the lab procedure of drug test processing include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary step of integrating a sample into a lab’s system. This step involves ensuring the sample’s seal and shipment integrity, allocating a unique LAN (Laboratory Accessioning Number), and completing any remaining information not covered by an electronic chain of custody system.

Screening is a preliminary assay for detecting drugs of potential abuse. While Screening is an economical approach for ruling out drug consumption in many samples, any positive initial test results must be verified before they are permissible in legal settings. Samples with a presumptive positive result in Screening need a follow-up confirmation.

If a sample shows a presumptive positive result during the Screening phase, additional hair is taken from the initial specimen for further Extraction. At this stage, drugs are extracted from hair at much lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening particularly challenging to execute.

Positive results from Screening undergo Confirmation using GC/MS, GC/MS/MS or LC/MS/MS. Any samples showing presumptive positives are cleaned before Confirmation as necessary. The complete lab process from Accessioning to Confirmation is evaluated under both CAP (College of American Pathologists) Hair standards and the accreditation to ISO / IEC 17025 standards.

Benefits of hair drug testing:

• Extended detection duration: Hair drug tests can confirm drug usage for up to 90 days, in contrast to urine tests, which offer shorter detection times.
• Resistance to manipulation: Cheating a hair drug test is challenging, thus enhancing the reliability of the results.
• Tracks historic usage: It provides a timeline of drug use over several months, as opposed to just recent consumption.

Downsides:

• Cannot detect recent consumption: Drugs only become visible in hair after approximately 5-7 days.
• Expense: Hair drug tests tend to be costlier than other drug testing approaches.
• Result variability: Variables such as hair color and unique characteristics in hair growth can influence the drug metabolite levels in hair.

Note: Frequently called "hair follicle tests", the analysis actually focuses on 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.

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.
