Hair Follicle Drug Testing - Washta, IA

What it is, How it works

Hair testing is recognized as an effective method for identifying drug and alcohol consumption. By embedding biomarkers in the fibers of the growing hair, it offers a comprehensive record of alcohol and drug use over time. Collected near the scalp, hair samples can potentially indicate substance usage over a span of up to three months. Collecting hair is straightforward, challenging to tamper with, and easy to transport.

A 1.5-inch section of around 200 strands (approximately the thickness of a #2 pencil) from the scalp yields 100mg, the preferred quantity for screening and confirmation. For tests like EtG, add-ons, and tests exceeding 10 panels, 150mg is advised. Using a jeweler’s scale to weigh the sample is suggested. If scalp hair isn't available, an equivalent portion of body hair can be used. Our term "head hair" specifically refers to scalp hair, whereas "body hair" covers all other categories (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test consists of four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the sample’s initial processing in a laboratory system, including proper sealing and shipment confirmation, random LAN (Laboratory Accessioning Number) assignment, and completing any missing data entry from non-electronic chain of custody systems.

Screening is a preliminary examination for drugs of misuse. Although cost-effective for ruling out drug presence in most samples, a positive screening necessitates confirmation for legal acceptability. Samples presumed positive require further confirmation.

If a sample shows a presumptive positive during Screening, additional hair is extracted from it and readied for Extraction. Here, drugs are isolated from the hair in much lower concentrations than other methods (e.g., urine or oral fluid), making hair drug testing the most intricate method to conduct.

For any presumptive positives, Confirmation is done using GC/MS, GC/MS/MS, or LC/MS/MS. Samples that are tentatively positive are cleaned before confirmation as needed. The complete laboratory procedure from Accessioning through Confirmation adheres to CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Capable of identifying drug consumption for up to 90 days, unlike urine tests with a shorter span.
• Resistant to evasion: The reliability of hair drug testing is higher due to its resistance to manipulation.
• Displays a usage history: It reflects a user’s drug intake trend over time, not just recent activity.

Limitations:

• Delay in detecting recent intake: Drugs become detectable in hair approximately 5-7 days post-use.
• Expense: Generally, hair drug testing incurs higher costs than other testing methods.
• Result variance: Influences such as hair color and personal hair growth differences can impact drug metabolite levels in hair.

Note: Often called "hair follicle tests," these actually analyze the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing in Washta, IA, outshines urine testing due to its longer detection window and greater accuracy. Unlike traditional urine tests, hair analysis offers a superior ability to track substance use over an extended period, ensuring fewer chances of escaping detection and better compliance with drug policies.

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.
