Hair Follicle Drug Testing - Kolin, MT

What it is, How it works

Hair analysis has become recognized as an effective technique for identifying drug and alcohol consumption. Hair offers a prolonged record of substances by capturing biomarkers in the fibers of the growing hair strand. When taken near the scalp, hair can offer up to about a 3-month detection period for alcohol and other substances. Hair collection is straightforward, relatively resistant to tampering, and simple to transport.

A section of 1.5 inches comprising roughly 200 strands of hair (approximately the width of a #2 pencil) nearest the scalp will provide 100mg of hair, which is the ideal portion for initial screening and confirmation. For EtG, additional assessments, and/or analyses beyond 10 panels, a sample of 150mg is advised. Utilizing a jeweler's scale is recommended for weighing the specimen. If scalp hair is unavailable, an equivalent portion of body hair can be obtained. The term 'head hair' specifically refers to scalp hair. 'Body hair' encompasses all other hair types (such as facial or axillary).

Process Summary

The laboratory processing for a drug test outcome includes four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial processing of a sample within a lab's framework. This step ensures that the sample was securely sealed and shipped, allocates a random LAN (Laboratory Accessioning Number), and finalizes any additional data input not supplied by an electronic chain of custody system.

Screening involves a preliminary rapid assessment for drugs of abuse. Although Screening is a cost-efficient method to eliminate drug usage in most samples, a positive screen must be substantiated for legal admissibility. Samples that show presumptive positives in Screening require a secondary confirmation.

If a sample receives a presumptive positive during the Screening phase, more hair is extracted from the original specimen for preparation in the Extraction step. During this phase, drugs are extracted at a lower concentration compared to other methods (e.g., urine or oral fluid), making hair drug screening the most challenging methodology to perform.

Confirmation for any positive screening result is performed via GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptive positive samples are cleaned prior to confirmation as necessary. The entire laboratory procedure from Accessioning through Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and the accreditation of ISO / IEC 17025 standards.

Benefits of hair drug testing:

• Extended detection timeframe: Hair drug tests can identify drug use up to 90 days, in contrast to urine tests which have a reduced detection period.
• Challenges in tampering: Hair drug testing is notably difficult to circumvent, ensuring more reliable results.
• Historical insights: It offers a consistent pattern of drug use over time instead of just current consumption.

Constraints:

• Cannot identify recent consumption: Drugs become detectable in hair roughly 5-7 days post-use.
• Expense: Hair drug tests are typically pricier compared to other drug testing techniques.
• Result variability: Variables like hair color and personal differences in hair growth may influence drug metabolite concentration in hair.

Note: Although commonly termed "hair follicle tests", the examination 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.
