Hair Follicle Drug Testing - Cloverland, WI

What it is, How it works

Regarded as a robust measure in detecting drug and alcohol consumption, hair testing captures a prolonged history of substance use by embedding biomarkers within the fibers of hair as it grows. When gathered near the scalp, hair samples can reveal usage over around a 3-month span for alcohol and other narcotics. Hair collection is straightforward, challenging to tamper with, and straightforward to transport.

A sample measuring 1.5 inches and containing roughly 200 hair strands (similar in size to a #2 pencil) from near the scalp yields 100mg of hair, which is the optimal sample size for analysis and verification. For tests involving EtG, additional substances, and panels exceeding 10, 150mg of hair is advisable. We suggest using a jeweler's scale to weigh the specimen. If scalp hair cannot be sourced, a comparable amount of body hair may be collected. By head hair, we specifically mean scalp hair. Body hair encompasses any other hair types (such as facial or axillary hair).

Process Overview

The laboratory processing of a drug test result comprises four main stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the initial phase where the sample is entered into the lab's database, ensuring the specimen was properly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and inputting any additional information not covered by an electronic chain of custody system.

Screening is a preliminary drug detection check. While a cost-efficient method to exclude drug consumption in most cases, a positive screening result must be verified for legal admissibility. Any samples indicating a presumptive positive from Screening necessitate further confirmation.

If Screening suggests a presumptive positive, additional hair is extracted from the initia source and prepared for Extraction. At this stage, drugs are isolated from hair at significantly lower concentrations compared to other methods (for example, urine or oral fluid), illustrating why hair drug analyses present considerable complexity.

Confirmation for any positive screening finding is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing prior to confirmation if required. The complete laboratory process from Accessioning through Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and conforms to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug assays detect narcotic usage up to 90 days, unlike urine analyses which have a more limited detection timeframe.
• Challenging to deceive: The difficulty in evading a hair drug test enhances result reliability.
• Supplies historical insight: Provides a timeline of substance use over an extensive period, not merely recent usage.

Limitations:

• Incapable of identifying recent consumption: Detection of drugs in hair takes roughly 5-7 days.
• Expense: Hair drug tests often carry greater costs compared to other methods.
• Result variability: Elements such as hair color and individual growth variations can influence drug metabolite quantities in hair.

Note: Despite being termed "hair follicle tests", the analysis focuses on the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why does hair follicle testing stand out compared to urine tests in Cloverland, WI? Hair testing showcases superior detection accuracy and reliability.

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.
