Hair Follicle Drug Testing - Houghton, MI

What it is, How it works

Hair analysis has emerged as a formidable method for detecting the consumption of drugs and alcohol. Hair records a prolonged history of alcohol and drug use by capturing biomarkers within the strands during growth. When taken near the scalp, hair offers a detection timeframe of roughly three months for alcohol and drugs. Hair is easy to gather, somewhat resistant to tampering, and convenient to transport.

A 1.5-inch section with around 200 hair strands (approximating the thickness of a #2 pencil) closest to the scalp yields 100mg of hair, the perfect amount for evaluation and validation. For EtG, add-ons, and/or examinations surpassing 10 panels, 150mg of the sample is advised. We suggest measuring the specimen with a jeweler’s scale. If scalp hair isn't available, a corresponding quantity of body hair can be collected. When mentioning head hair, we specifically mean scalp hair. Conversely, body hair applies to all other types (facial, axillary, etc.).

Process Overview

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

Accessioning signifies the initial integration of a sample into a lab’s system. This step involves ensuring the sample was properly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and fulfilling any extra data input not handled by an electronic custody chain system.

Screening provides an initial rapid assessment for substances of abuse. Although Screening offers a cost-efficient approach to exclude drug use for most samples, a positive screen requires validation for court acceptance. Any samples that test presumptively positive in Screening necessitate a subsequent confirmation.

If a sample tests presumptively positive in Screening, more hair is extracted from the original sample for Preparation. In this phase, substances are extracted from hair at markedly lower concentrations compared to other procedures (like urine or oral fluid), making hair drug examination the most challenging technique to undertake.

Validation of any positive screening outcome occurs through GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are cleansed prior to validation, as necessary. The entire lab process, from Accessioning to Confirmation, is reviewed under CAP (College of American Pathologists) Hair designation and accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can recognize drug use for up to 90 days, unlike urine tests that have a briefer detection timeframe.
• Challenging to cheat: Hair drug tests are difficult to trick, ensuring more precise results.
• Offers historical data: It reveals a drug use pattern over time, not just recent consumption.

Limitations:

• Inability to identify recent use: It requires about 5-7 days for drugs to be traceable in hair.
• Expense: Hair drug tests tend to be costlier than other testing options.
• Result discrepancies: Factors like hair color and personal hair growth variations can impact the drug metabolite concentration in hair.

Note: Although often termed "hair follicle tests," the examination targets the hair strand itself and not the hair follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

When comparing hair follicle testing in Houghton, MI, to traditional urine tests, the superior detection capabilities are evident. Hair tests offer greater accuracy and reliability, ensuring that even longer-term drug use is uncovered.

While urine tests capture recent drug intake, hair testing provides a comprehensive review, proving more robust against attempts to mask substance use.

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.
