Hair Follicle Drug Testing - Staples, MN

What it is, How it works

Hair examinations have become recognized as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged record of alcohol and other substances by encasing biomarkers within the structure of the hair strand as it grows. When obtained near the scalp, hair can offer up to roughly a 3-month period for alcohol and drug detection. Hair is straightforward to gather, relatively challenging to alter, and convenient to transport.

A 1.5-inch section comprising approximately 200 hair strands (equivalent to a #2 pencil) nearest to the scalp delivers 100mg of hair, the optimum sample for inspection and validation. For EtG, supplements, and/or analyses exceeding 10 panels, 150mg of the hair sample is advisable. We suggest assessing the sample with a jeweler’s scale. If scalp hair is not accessible, a comparable quantity of body hair may be obtained. In discussions of head hair, we are exclusively referring to scalp hair. Body hair pertains to all other varieties (facial, axillary, etc.).

Process Overview

The four primary phases in the laboratory processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial handling of a sample into a laboratory’s framework. This includes confirming the sample was sealed and dispatched correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry not offered by an electronic chain of custody mechanism.

Screening involves an initial rapid inspection for drugs of abuse. While Screening is a cost-efficient method to dismiss drug consumption on the majority of samples, a positive screen must be authenticated to be valid in legal contexts. Any samples presumptively positive in Screening do necessitate further confirmation.

If a sample is presumptively positive in the Screening phase, additional hair is extracted from the initial specimen and prepared for Extraction. In this phase, drugs are derived from hair at a much lower concentration than in alternative methodologies (e.g., urine or oral fluid), making hair drug examination the most complex methodology to implement.

Confirmation of any positive screening result is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as necessary. The entire laboratory process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug assessments can recognize drug usage for up to 90 days, unlike urine evaluations which have a shorter detection period.
• Hard to manipulate: It is exceedingly challenging to deceive a hair drug test, ensuring more precise results.
• Shows past usage: It can display a pattern of drug consumption over a span, not merely recent use.

Limitations:

• Incapable of detecting recent consumption: It takes around 5-7 days for drugs to be traceable in hair.
• Expense: Hair drug evaluations are generally more costly than other drug testing techniques.
• Inconsistencies in outcomes: Elements such as hair color and individual differences in hair growth can influence drug metabolite concentration in the hair.

Note: While commonly called "hair follicle tests", the examination itself analyzes the hair strand and 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. 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.
