Hair Follicle Drug Testing - Manchester, WI

What it is, How it works

Hair testing is recognized as a potent method for revealing drug and alcohol consumption. Hair encapsulates a prolonged history of substances by embedding biomarkers in the growing strand's fibers. When hair near the scalp is collected, it can offer a detection timeframe up to roughly 3 months for alcohol and other substances. Hair is easy to collect, relatively hard to tamper with, and simple to transport.

A sample measuring 1.5 inches with approximately 200 hair strands (similar to the thickness of a #2 pencil) closest to the scalp provides 100mg of hair, which is ideal for screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, it is advised to collect 150mg of the sample. Utilizing a jeweler’s scale to weigh the specimen is suggested. If scalp hair is absent, an equivalent amount of body hair is acceptable. When referring to head hair, we are specifically indicating scalp hair. Body hair encompasses all other hair categories (facial, axillary, etc.).

Process Overview

The core steps in laboratory processing of a drug test outcome encompass Accessioning, Screening, Extraction, and Confirmation.

Accessioning starts with initial sample processing in a lab's system. This phase involves ensuring the sample was properly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any outstanding data entry absent in an electronic chain of custody system.

Screening consists of a swift preliminary examination for drugs of abuse. Screening offers a cost-efficient method to exclude drug use in most samples, however, a positive screen must be corroborated to be permissible in legal proceedings. Presumptive positive results in Screening necessitate secondary confirmation.

In the event of a presumptive positive result during Screening, additional hair is extracted from the original sample and readied for Extraction. During this phase, drugs are extracted from hair at concentrations significantly lower than other methodologies (such as urine or oral fluid), making hair drug testing the most intricate methodology to execute.

Confirmation of any positive screen results is conducted through GC/MS, GC/MS/MS or LC/MS/MS. Before confirmation, all presumptive positive samples are washed as required. The complete laboratory process from Accessioning through to Confirmation is examined under both CAP (College of American Pathologists) Hair designation and conforms with the accreditation to ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests, which offer shorter detection periods.
• Challenging to falsify: Hair drug tests are very difficult to manipulate, enhancing result accuracy.
• Offers historical insight: They provide details on drug use patterns over time, not merely recent consumption.

Limitations:

• Incapable of identifying recent use: It generally takes 5-7 days for drugs to appear in hair samples.
• Expense: Hair drug tests tend to be more costly than alternative drug testing methods.
• Result variations: Elements like hair color and personal hair growth differences can impact the concentration of drug metabolites in hair.

Note: Despite frequently being named "hair follicle tests", this test evaluates the hair strand and not the hair follicle under 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.
