Hair Follicle Drug Testing - Bremen, IN

What it is, How it works

Hair analysis is regarded as an effective method for detecting drug and alcohol consumption. Hair strands capture historical data of alcohol and drugs by encasing biomarkers within the hair's structure as it grows. When taken near the scalp, hair can reveal a detection window of up to 3 months for alcohol and substances. Hair sampling is straightforward, relatively tamper-resistant, and easily transportable.

A length of 1.5 inches of approximately 200 hair strands (around the width of a #2 pencil) from the scalp yields 100mg of hair, which is the optimal sample for both screening and confirmation purposes. For comprehensive EtG, extra tests, and/or analyses exceeding 10 panels, a sample of 150mg is suggested. It is advisable to weigh the specimen using a jeweler’s scale. In the absence of scalp hair, a comparable quantity of body hair may be utilized. "Head hair" specifically denotes scalp hair. "Body hair" encompasses all other hair varieties (facial, axillary, etc.).

Process Overview

The four principal stages in laboratory drug test processing are Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the initial sample processing within a laboratory’s infrastructure. This process checks if the sample is properly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any supplementary data input not covered by an electronic chain of custody system.

Screening is an initial rapid assessment for drugs of abuse. While Screening efficiently eliminates drug use in most samples, a positive result must be confirmed for legal admissibility. Samples showing presumptive positivity during Screening must undergo secondary confirmation.

In cases of presumptive positivity during Screening, more hair is drawn from the initial sample for Extraction. At this stage, drugs are removed from the hair at lower concentrations compared to other techniques (e.g., urine or oral fluid), making hair drug testing one of the most challenging methodologies to execute.

Positive Screening results are verified through GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with presumptive positivity undergo washing before confirmation as required. The entire laboratory sequence from Accessioning to Confirmation is scrutinized under the guidelines of the CAP (College of American Pathologists) Hair designation and aligns with ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug assessments can trace chemical use for as long as 90 days, unlike urine tests with shorter periods.
• High reliability: Cheating on a hair drug test is extremely difficult, ensuring more accurate results.
• Tracks historical use: Provides insights into a pattern of substance use over time, not just immediate usage.

Limitations:

• Inability to detect recent intake: A timespan of around 5-7 days is needed before drugs are traceable in hair.
• Expense: Hair drug analyses are typically more costly than alternative testing approaches.
• Result variability: Aspects like hair color and individual hair growth differences may influence drug metabolite levels in hair.

Note: Although often termed as "hair follicle tests", the procedure examines the hair strand itself and not the follicle beneath the skin

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.
