Hair Follicle Drug Testing - Gunder, IA

What it is, How it works

Hair analysis has emerged as an effective method for assessing drug and alcohol consumption. Hair holds a prolonged history of substance use by capturing biomarkers within the fibers of the hair shaft as it grows. A sample taken near the scalp can offer an approximate 3-month window for detecting alcohol and other drugs. Hair collection is straightforward, relatively challenging to tamper with, and convenient for transportation.

A 1.5-inch segment consisting of around 200 hair strands (roughly matching the diameter of a #2 pencil) near the scalp yields 100mg of hair, which is ideal for screening and confirmation processes. For analyses involving EtG, additional tests, or panels exceeding 10, 150mg of the sample is advisable. It's recommended to weigh the sample using a jeweler’s scale. If scalp hair is insufficient, a similar quantity of body hair may be gathered. When discussing head hair, it specifically pertains to scalp hair alone. Body hair encompasses all other types (such as facial, axillary, etc.).

Process Overview

The procedure for lab analysis of a drug test result encompasses four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial entry of a sample into a laboratory's records. This step verifies the sample’s proper sealing and delivery, assigns a random LAN (Laboratory Accessioning Number), and completes any extra data entry not covered by an electronic chain of custody.

Screening conducts a preliminary evaluation for drugs of abuse. While it is an economical approach for excluding drug consumption in most samples, a beneficial screen must be confirmed for court admissibility. Samples showing presumptive positives in Screening necessitate additional confirmation.

If a sample shows a presumptive positive in Screening, extra hair is retrieved from the primary specimen for Extraction. During this phase, drugs are drawn out from hair at much lower concentrations than other methods (e.g., urine or oral fluid), underscoring why hair drug screening is notably intricate.

Confirmation of any positive screen result is completed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleansed before confirmation as warranted. The review of the entire lab process from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair specifications and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests reveal drug use for as long as 90 days, unlike urine tests which have a shorter detection span.
• Challenging to falsify: Cheating on a hair drug test is significantly difficult, leading to more reliable outcomes.
• Offers historical insight: It can exhibit a trend of drug use over a longer duration, beyond just recent use.

Limitations:

• Incapable of identifying recent use: Drug traces typically appear in hair after approximately 5-7 days.
• Expense: Hair drug tests are typically pricier than other drug testing methods.
• Result variability: Elements like hair color and individual hair growth variations can influence drug metabolite concentrations in the hair.

Note: Commonly labeled as "hair follicle tests", the analysis actually examines the hair strand, not 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.
