Hair Follicle Drug Testing - Fordyce, AR

What it is, How it works

Hair screening has emerged as a significant method for identifying drug and alcohol consumption. Hair offers an extended timeline of drug and alcohol use by integrating biomarkers within the strands of the developing hair. When taken from near the scalp, hair can reveal drug and alcohol usage within an estimated three-month detection period. It is easy to gather, somewhat tough to alter, and straightforward to transport.

A lock measuring 1.5 inches, comprising roughly 200 hairs (comparable to a #2 pencil thickness) near the scalp yields 100mg, which is the preferred quantity for analysis and verification. For EtG, additional tests, and/or panels exceeding 10, 150mg is advised. We propose using a jeweler’s scale to weigh the sample. In the absence of scalp hair, a similar quantity of body hair can be used. “Head hair” pertains exclusively to scalp hair. “Body hair” involves all other categories (facial, underarm, etc.).

Process Overview

The processing of a drug test result in a lab involves four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial handling of a specimen within a lab’s system. This covers checking that the sample was properly sealed and shipped, allotting it a random LAN (Laboratory Accessioning Number), and entering any data that might not have been furnished by an electronic chain of custody.

Screening executes a preliminary rapid assessment for abuse substances. While it is an economically sensible technique to eliminate drug use in most samples, a positive screen requires confirmation for courtroom validity. All samples that test positive in Screening go through further validation.

Upon a presumptive positive in the Screening phase, more hair is taken from the original sample for Extraction. Here, drugs are sourced from hair at considerably lower concentrations than with other methods (e.g., urine or saliva), making hair drug testing notably challenging.

Subsequent confirmation of any positive screen is accomplished through GC/MS, GC/MS/MS, or LC/MS/MS. All samples that appear positive go through a washing process ahead of confirmation as necessary. From Accessioning to Confirmation, the entire laboratory procedure is conducted aligned with the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Prolonged detection span: Hair drug tests detect drug consumption over a 90-day period, unlike urine tests, which have a shorter timeframe.
• Hard to manipulate: It's quite difficult to deceive a hair drug test, lending more reliability to the results.
• Offers usage history: It provides an account of drug use over time, beyond just recent activity.

Limitations:

• Inability to identify recent intake: Detection in hair takes roughly 5-7 days.
• Expense: Hair drug tests tend to be pricier than other testing techniques.
• Result variability: Aspects such as hair color and personal hair growth differences can influence drug metabolite concentration in hair.

Note: Although termed as "hair follicle tests", it analyzes the hair strand rather than 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. 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.
