Hair Follicle Drug Testing - Gillespie, IL

What it is, How it works

Hair examinations have been increasingly recognized as an effective technique for detecting drug and alcohol consumption. Hair retains a comprehensive timeline of alcohol and drugs by capturing biomarkers within the strands of the growing hair shaft. When clipped near the roots, hair can offer up to a 3-month detection period for alcohol and substances. It is easy to collect, somewhat resistant to tampering, and convenient to transport.

A 1.5-inch portion of roughly 200 hair strands (comparable to the width of a #2 pencil) near the scalp will provide 100mg of hair, which is the ideal sample for both screening and confirmation procedures. For EtG, additional tests, and/or panels exceeding 10, a 150mg sample is advisable. Measuring the sample with a jeweler’s scale is recommended. Should scalp hair not be present, an equivalent quantity of body hair can be used. When mentioning head hair, we specify scalp hair exclusively. Body hair includes all other hair types (facial, axillary, etc.).

Process Overview

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

Accessioning includes the initial recording of a sample within the lab’s system. This involves confirming that the sample was properly sealed and sent, assigning it a random LAN (Laboratory Accessioning Number), and completing any outstanding data entry absent from an electronic chain of custody system.

Screening comprises a preliminary check for drugs of abuse. Screening serves as a cost-effective measure to eliminate drug use in most samples, yet a positive screen requires confirmation to stand as evidence in court. Any samples showing a presumptive positive in Screening need a subsequent confirmation check.

Samples with a presumptive positive result during the Screening phase undergo further hair extraction from the initial sample and are prepared for Extraction. During this stage, drugs are extracted at a substantially lower concentration than in other methods (e.g., urine or oral fluids), making hair drug testing one of the most complex methodologies to undertake.

Confirmation for any positive screening result utilizes methods such as GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive undergo washing before confirmation as necessary. From commencement at Accessioning to the end at Confirmation, every step of the lab process is assessed under the CAP (College of American Pathologists) Hair designation alongside accreditation to ISO / IEC 17025 standards.

Benefits of hair drug testing:

• Extended detection span: Hair drug tests can trace drug consumption for up to 90 days, in contrast to urine tests which have a reduced detection duration.
• Challenging to evade: It is notably difficult to manipulate a hair drug test, enhancing the reliability of the results.
• Delivers longitudinal data: It can present a timeline of drug use habits over time, rather than merely recent acts of use.

Limitations:

• Inability to identify recent use: It takes around 5-7 days for drugs to become detectable within hair.
• Expense: Hair drug tests typically come at a higher cost compared to other drug testing methods.
• Result variability: Aspects like hair color and personal differences in hair growth can impact the concentration of drug metabolites in the hair.

Note: Although often labeled as "hair follicle tests", the test itself analyzes the hair strand and not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Gillespie, IL, hair follicle testing is distinctly advantageous over traditional urine tests. Enhanced detection and extended windows make hair testing the preferred choice for discerning individuals.

Urine tests, although standard, may not reveal chronic use as effectively. In contrast, hair tests embody reliability and are a testament to thorough and reliable drug history analysis.

Extended Detection Window

Hair follicle testing in Gillespie, IL provides an extended detection window, exposing drug use for up to 90 days. This lengthy timeframe allows employers to have a thorough understanding of an individual's drug history.

Employers benefit from the capacity of hair tests to reveal past drug use over months, rather than just days, providing a complete picture of an individual's substance habits.

Tamper-Resistant Testing Method

In Gillespie, IL, hair follicle tests significantly mitigate risks of tampering. Unlike urine samples, which can be adulterated, hair samples remain protected and intact.

The robust nature of hair testing ensures outcomes that are reliable and unquestioned, providing confidence in the accuracy and integrity of the results.

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.
