Hair Follicle Drug Testing - Cave City, KY

What it is, How it works

Hair analysis is increasingly considered an effective method for identifying drug and alcohol consumption. Hair encapsulates a prolonged record of alcohol and drugs, as biomarkers embed themselves within the fibers as the hair grows. When the sample is taken near the scalp, it can provide a detection window of up to roughly 90 days for alcohol and other drugs. Collection is straightforward, it is challenging to alter, and it is convenient to transport.

A 1.5-inch hair sample, consisting of around 200 strands (approximately the thickness of a #2 pencil) near the scalp, yields 100mg of hair, which is the preferred quantity for initial screening and confirmatory tests. For EtG assessments, additional tests, and/or screenings beyond 10 panels, a minimum of 150mg of the sample is advised. It is best to use a jeweler’s scale to weigh the sample. Should scalp hair be unavailable, an equivalent quantity of body hair can be gathered. By 'head hair', we mean only the hair on the scalp. The term 'body hair' denotes any other types of hair (such as facial or axillary hair).

Process Overview

The key processes in the laboratory evaluation of a drug test result consist of Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the initial entry of a sample into a laboratory system, encompassing checks to ensure the sample was adequately sealed and sent, the assignment of a unique LAN (Laboratory Accessioning Number), and the completion of any additional data input absent from an electronic chain of custody system.

Screening entails a preliminary assessment to detect drugs of abuse. While an economical solution to eliminate drug usage in most samples, confirmation is imperative for any positive screen that is intended to be court-admissible. Samples returning a presumptive positive from the Screening stage require further verification.

If there's a presumptive positive in Screening, more hair is taken from the original sample and prepared for Extraction. This phase involves extracting drugs at a far lower concentration from hair than from other samples (such as urine or oral fluids), making hair drug screening the most challenging technique to execute.

Confirmation for any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, presumptive positive samples are cleaned as needed. The entire testing pathway from Accessioning to Confirmation is scrutinized following both the CAP (College of American Pathologists) Hair designation and accreditation according to ISO / IEC 17025 guidelines.

Advantages of hair drug testing:

• Prolonged detection period: Hair tests reveal drug use for up to 90 days, contrasting with urine tests which have a shorter timeframe.
• Hard to fake: Manipulating hair drug tests is quite difficult, bolstering the credibility of results.
• Shows historical patterns: Offers a timeline of drug use over an extended duration, not merely recent consumption.

Limitations:

• No immediate use detection: Drugs become detectable in hair only after approximately 5-7 days.
• Price: Hair drug testing tends to be costlier compared to other drug testing methods.
• Result variability: Factors such as hair pigmentation and individual hair growth differences can influence drug metabolite levels in the hair.

Note: Commonly termed as "hair follicle tests", the examination targets 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. 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.
