Hair Follicle Drug Testing - Bete Grise, MI

What it is, How it works

Hair testing is regarded as a formidable means for detecting alcohol and drug use. Hair captures a comprehensive timeline of substance consumption by embedding biomarkers within the fibers of the maturing hair strand. When obtained near the scalp, it offers an approximate 3-month timeframe for identifying alcohol and drug presence. Collecting hair is straightforward, hard to tamper with, and simple to transport.

A sample of 1.5 inches consisting of roughly 200 strands close to the scalp provides 100mg, which is optimal for examination and verification. For EtG, additional tests, and/or panels exceeding 10, 150mg of hair is advised. It's suggested to weigh the sample with a jeweler’s scale. If scalp hair isn't present, a comparable amount of body hair can be sourced. References to head hair signify scalp hair solely, whereas body hair pertains to other types (facial, axillary, etc.).

Process Overview

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

Accessioning encompasses the preliminary processing of a sample into a lab's database. This step verifies proper sealing and shipping of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes any necessary data entry not included by an electronic chain of custody.

Screening conducts an initial swift analysis for drugs of abuse. Although Screening serves as a cost-effective method to preclude substance use on many samples, confirmation is required for any screen to be admitted in court. Presumably positive samples in Screening mandate a secondary confirmation.

For presumptive positives in the Screening phase, more hair is extracted from the initial collection and readied for Extraction. In this phase, drugs are isolated from hair at a substantially lower concentration compared to other methods (e.g., urine or oral fluid), rendering hair drug screening a challenging technique.

Confirmation of any positive screening outcome is executed utilizing GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing pre-confirmation as necessary. The comprehensive lab procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the accreditation conforming to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests ascertain drug use for as long as 90 days, unlike urine tests with a limited detection window.
• Challenging to evade: Evading a hair drug test is extremely challenging, lending to more precise outcomes.
• Reveals usage history: It uncovers a pattern of drug habits over time, instead of merely recent usage.

Limitations:

• Incapable of catching recent activity: Drugs require about 5-7 days to become identifiable in hair.
• Expense: Compared to other methods, hair drug tests are generally pricier.
• Result variability: Elements like hair color and unique differences in hair growth can influence the concentration of drug metabolites.

Note: Although often called "hair follicle tests", the analysis examines the hair strand without involving the hair follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing is preferred over urine testing in Bete Grise, MI, due to its superior accuracy and reliability. While urine tests detect recent usage, hair tests reveal a longer history of substance use, offering an advantage for employers wanting to maintain a safe workplace environment.

Extended Detection Window

For employers in Bete Grise, MI, hair follicle testing is valuable for its extended detection window, identifying drugs used up to 90 days earlier. This comprehensive view into an employee’s substance history is a key tool in workforce management and ensuring workplace safety.

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.
