Hair Follicle Drug Testing - Fisher, MN

What it is, How it works

Hair analysis is increasingly recognized as a crucial method for identifying drug and alcohol consumption. Hair captures long-term evidence of alcohol and drug usage by embedding biomarkers in the strands of growing hair. A sample taken near the scalp can reveal drug and alcohol presence for up to roughly a three-month period. Collecting hair is straightforward, challenging to tamper with, and convenient to transport.

A 1.5-inch segment of about 200 hair strands (approximately the thickness of a #2 pencil) taken near the scalp yields 100mg of hair, the optimal quantity for screening and verification. For EtG, additional tests, and/or those exceeding 10 panels, 150mg of the specimen is advised. It’s recommended to measure the specimen using a jeweler’s scale. Should scalp hair be unavailable, an equivalent volume of body hair can be utilized. References to head hair pertain solely to scalp hair. Body hair covers all remaining hair types (facial, axillary, etc.).

Process Overview

The primary stages in processing a laboratory drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary handling of a sample within a lab’s framework. This process encompasses confirming proper sealing and shipment of the sample, allotting a random LAN (Laboratory Accessioning Number), and completing any extra data input not available through an electronic chain of custody system.

Screening features an initial rapid assessment for drugs of abuse. While Screening serves as a cost-efficient strategy to exclude drug use in most cases, a confirmed screen is necessary for legal admissibility. Samples testing presumptive positive in Screening necessitate a follow-up confirmation.

Upon a presumptive positive result at the Screening phase, additional hair is retrieved from the initial specimen for Extraction. Here, drugs are extracted from hair at lower concentrations compared to other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.

Confirmation of any positive screen outcome employs GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive undergo washing prior to confirmation as required. From Accessioning to Confirmation, the laboratory process is scrutinized under the CAP (College of American Pathologists) Hair designation and accreditation to ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extensive detection period: Hair drug tests reveal drug usage for up to 90 days, unlike urine tests with a shorter detection span.
• Resistance to deception: It is exceedingly difficult to manipulate a hair drug test, ensuring the accuracy of results.
• Historical data provision: It offers a pattern of drug use over time instead of just recent consumption.

Limitations:

• Incapable of detecting recent use: Drugs become noticeable in hair after about 5-7 days.
• Expense: Hair drug tests are typically pricier compared to other methods.
• Result variation: Elements like hair color and individual hair growth differences can impact drug metabolite concentration in the hair.

Note: Although often termed as "hair follicle tests", the examination actually evaluates the hair strand, not the hair 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.
