Hair Follicle Drug Testing - Harrietta, MI

What it is, How it works

Hair analysis is widely recognized as an effective method for detecting drug and alcohol consumption. Hair captures a comprehensive historical record of substance use by embedding biomarkers within the fibers of the hair as it grows. When taken near the scalp, hair can reveal substance use for as long as around three months. Collecting hair is straightforward, challenging to tamper with, and simple to send for analysis.

A 1.5-inch portion involving roughly 200 hair strands (similar to the size of a #2 pencil) nearest to the scalp results in 100mg of hair, which is the optimal sample for both screening and confirmation. For EtG, additional tests, and/or screenings beyond 10 panels, it is advised to have 150mg of the sample. It is suggested to weigh the sample using a jeweler’s scale. Should scalp hair be unobtainable, an equivalent amount of body hair may be used. By head hair, we mean scalp hair exclusively. Body hair encompasses any other types of hair (facial, axillary, etc.).

Process Overview

The primary stages in laboratory analysis of a drug test result comprise Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial intake of a sample into a laboratory’s system. Tasks include confirming the appropriate sealing and shipping of the sample, assigning a unique LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent from an electronic chain of custody system.

Screening includes an initial rapid assessment for substances of abuse. While cost-efficient for dismissing drug use in most samples, any positive results in screening necessitate confirmation to be legally valid. Any presumptively positive samples in screening will require additional confirmation.

Where a sample is indicated as presumptively positive in the Screening phase, additional hair is sourced from the initial specimen for the Extraction phase. At this point, drugs are isolated from hair at significantly lower concentrations compared to other techniques (e.g., urine or oral fluids), highlighting why hair drug screening is particularly complex to execute.

Confirmatory analysis of any positive screening outcomes is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation if required. From Accessioning to Confirmation, the entire laboratory procedure is scrutinized according to both CAP (College of American Pathologists) Hair standards and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can unveil drug use extending up to 90 days, whereas urine testing offers a shorter detection duration.
• High accuracy: Tampering with a hair drug test is exceptionally challenging, thereby enhancing result reliability.
• Chronological insight: It presents a timeline of drug consumption over an extended period, rather than mere recent use.

Limitations:

• Delayed detection: It generally requires 5-7 days before substances become traceable in hair.
• Expense: Generally, hair drug testing incurs higher costs than other drug testing techniques.
• Result variability: Factors like hair color and individual growth patterns can influence drug metabolite concentrations in hair.

Note: Commonly termed as "hair follicle tests", these tests actually analyze the hair strand, not the underlying follicle in the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing in Harrietta, MI is proving more effective than urine testing when it comes to detection accuracy and reliability. While urine tests capture recent drug use, hair tests offer an extensive overview of past consumption.

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.
