Hair Follicle Drug Testing - Oronoco, MN

What it is, How it works

Hair testing is regarded as an effective method for identifying drug and alcohol consumption. Hair offers a prolonged history of alcohol and drug exposure by capturing biomarkers within the strands of emerging hair. When obtained close to the scalp, hair can reveal up to a 3-month detection period for alcohol and drugs. Hair is straightforward to gather, relatively hard to tamper with, and uncomplicated to send.

A 1.5-inch segment containing around 200 hair strands (approximately the diameter of a #2 pencil) nearest the scalp will yield 100mg of hair, the optimal sample for evaluation and verification. For EtG, add-ons, and/or assessments beyond 10 panels, 150mg of the sample is suggested. It is advisable to measure the sample using a jeweler’s scale. If scalp hair cannot be collected, a matching quantity of body hair might be used. When mentioning head hair, we only imply scalp hair. Body hair involves all different hair types (facial, axillary, etc.).

Process Overview

The core stages involved in the lab processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the primary processing of a sample into a laboratory's system. This comprises verifying that the sample was sealed and dispatched correctly, assigning a distinctive LAN (Laboratory Accessioning Number), and fulfilling any added data input not supplied by an electronic chain of custody system.

Screening entails an initial swift assessment for drugs of abuse. While Screening is an economical approach to exclude drug usage on most samples, a positive screen must be validated to be permissible in legal proceedings. Any samples that are tentatively positive in Screening do necessitate subsequent confirmation.

If a sample is tentatively positive in the Screening phase, additional hair is taken from the initial sample and prepared for Extraction. In this phase, drugs are isolated from hair at a considerably lower concentration compared to other methods (e.g., urine or oral fluid), making hair drug screening the most challenging methodology to execute.

Confirmation of any positive screening outcome is executed via GC/MS, GC/MS/MS or LC/MS/MS. All tentative positive samples are cleansed before confirmation as required. The complete lab process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extensive detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which have a shorter detection timeframe.
• Challenging to manipulate: It is highly challenging to evade a hair drug test, thus making the outcomes more reliable.
• Offers historical insights: It can illustrate a pattern of drug use over time, not merely recent consumption.

Limitations:

• Can't identify recent usage: It takes roughly 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests are typically pricier than other drug testing methods.
• Result variability: Elements such as hair color and personal variations in hair growth can influence the concentration of drug metabolites in the hair.

Note: Though often described as "hair follicle tests", the test itself evaluates the hair strand and 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. 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.
