Hair Follicle Drug Testing - Mahtomedi, MN

What it is, How it works

Hair analysis is regarded as a compelling method for identifying drug and alcohol consumption. As hair grows, biomarkers are captured within the hair strand fibers, offering a prolonged record of alcohol and drug use. Collected close to the scalp, hair can yield a detection window of roughly 3 months for substances. It's easy to collect, hard to tamper with, and straightforward to transport.

A 1.5-inch hair sample, consisting of around 200 strands (comparable to a #2 pencil) nearest the scalp, will produce 100mg, which is the optimal amount for both screening and verification. For EtG add-ons, and/or tests exceeding 10 panels, a sample size of 150mg is advised. We suggest utilizing a jeweler’s scale to weigh the sample. If scalp hair is not accessible, an equivalent quantity of body hair may be gathered. When mentioning head hair, we mean only scalp hair. Body hair encompasses all other types (such as facial and axillary hair).

Process Overview

The laboratory processing of a drug test incorporates four crucial stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary handling of a sample into a lab's system, ensuring the sample was appropriately sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry absent in the electronic custody documentation.

Screening functions as a preliminary assessment for drug presence. While it offers a cost-effective means to exclude drug use from most samples, any positive screen outcome must be affirmed to be valid in court. Samples testing positive in Screening need a further confirmation.

If a sample returns presumptive positive at the Screening phase, more hair is extracted from the initial sample for the Extraction process. Here, drugs are retrieved from the hair at significantly lower concentrations than with other methods (like urine or oral fluid), which makes hair drug screening the most challenging technique to execute.

Confirmation of positive screenings is achieved via GC/MS, GC/MS/MS, or LC/MS/MS methods. All samples presumed positive undergo washing before confirmation if required. The comprehensive laboratory process from Accessioning through to Confirmation adheres to both CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Hair drug testing advantages:

• Extended detection period: Hair tests can uncover drug consumption for up to 90 days, compared to the shorter detection windows of urine tests.
• High resistance to cheating: Hair drug tests are notably resistant to manipulation, enhancing the accuracy of results.
• Historical consumption insight: Hair tests can illustrate a timeline pattern of drug usage, not just recent consumption.

Limitations:

• Inability to detect recent use: Drugs typically become traceable in hair within 5-7 days.
• Pricing: Hair drug screenings generally carry higher costs than other methods.
• Result variability: Elements such as hair color and individual growth differences can influence the quantities of drug metabolites in hair.

Note: Although often described as "hair follicle tests", the test evaluates 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.
