Hair Follicle Drug Testing - West Denton, MD

What it is, How it works

Hair testing is increasingly recognized as an effective method for identifying drug and alcohol use. Hair offers an extended historical record of these substances by embedding biomarkers within the growing hair fibers. When collected near the scalp, hair can reveal use within a roughly three-month period for alcohol and other substances. It is easy to gather, moderately resistant to tampering, and straightforward to transport.

A 1.5-inch portion consisting of approximately 200 hair strands (around the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the preferred sample size for both screening and confirmation. For EtG, additional tests beyond 10 panels require 150mg of the sample. Utilizing a jeweler’s scale for weighing the sample is advisable. In the event that scalp hair is not obtainable, an equivalent quantity of body hair can be used. When discussing head hair, it specifically means scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The laboratory analysis of a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial integration of a sample into the laboratory system. This process includes ensuring that the sample was correctly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and performing any supplementary data input not covered by an electronic chain of custody system.

Screening provides a preliminary rapid assessment for drugs of abuse. While Screening offers a cost-effective means to eliminate drug use in most samples, any positive results require confirmation to be court-admissible. Samples with presumptive positives in Screening necessitate further confirmation.

Should a sample show presumptive positivity during Screening, additional hair is taken from the original sample and readied for Extraction. This step involves extracting drugs from hair at significantly lower concentrations than other methods (such as urine or oral fluid), which is why hair drug screening is notably challenging.

Positive screening results undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS methods. All presumptive positive samples receive a wash if needed before confirmation. The complete laboratory process from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for as long as 90 days, which is longer than the detection window for urine tests.
• Challenges with deception: Cheating a hair drug test proves very challenging, thereby enhancing result accuracy.
• Offers historical records: It provides a pattern of substance use over time, beyond just recent use.

Limitations:

• Lacks detection for recent use: Drugs become detectable in hair after approximately 5-7 days.
• Expense: Hair drug tests typically cost more compared to other drug testing methods.
• Result variations: Factors such as hair color and individual hair growth differences can influence drug metabolite concentration in hair.

Note: Though often called "hair follicle tests", the test examines the hair strand and not the hair follicle itself beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

When comparing hair follicle tests to urine testing in West Denton, MD, the advantages of hair testing stand out. The key benefit lies in its superior detection accuracy, offering a clearer picture of substance use over a longer period. Unlike urine tests, which can only detect recent usage, hair testing provides a broader perspective, enhancing the reliability and comprehensiveness of the results.

Extended Detection Window

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.
