Hair Follicle Drug Testing - Reece City, AL

What it is, How it works

Hair testing is increasingly recognized as an effective means for identifying drug and alcohol use. Hair retains a comprehensive record of alcohol and other drug intakes, capturing biomarkers in the strands' fiber as they grow. Sampling hair close to the scalp can furnish up to roughly a 90-day detection period for alcohol and other substances. Hair is easy to collect, hard to tamper with, and simple to send.

A sample measuring 1.5 inches comprising around 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp is needed to obtain 100mg, the optimal amount for screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg is preferred. It is advisable to measure the sample weight using a jeweler's scale. If scalp hair is unavailable, collect an equivalent amount of body hair. Mention of head hair specifically refers to scalp hair, whereas body hair encompasses all other types such as facial, axillary, etc.

Process Overview

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

Accessioning includes initially bringing a sample into a lab’s system. It covers verifying the sample’s proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and finishing any additional data entry missing from an electronic chain of custody system.

Screening denotes an initial brief examination for drugs of abuse. As a cost-effective approach to exclude drug use in most samples, a positive screening must be confirmed to be acceptable in court. Any samples suggesting a positive result in Screening require a secondary confirmation.

Should a sample suggest a positive result at the Screening stage, additional hair from the original specimen is sourced and readied for Extraction. During this phase, drugs are removed from hair at notably lower concentrations compared to alternative methods (such as urine or oral fluid), making hair drug screening the most complex method to execute.

Confirmation for any positive screening outcome is done using GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicating presumptive positives are cleaned before confirmation as required. The complete laboratory process from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can identify drug usage for up to 90 days, whereas urine tests offer a shorter detection period.
• Difficulty to cheat: Cheating on a hair drug test is extremely hard, enhancing result accuracy.
• Provides historical data: It can depict a drug use trend over a span of time, not merely recent usage.

Limitations:

• Cannot detect recent use: It takes roughly 5-7 days for substances to become detectable in hair.
• Cost: Hair drug tests are typically more costly compared to other drug testing techniques.
• Variations in results: Differences such as hair color and individual hair growth rates can influence drug metabolite concentrations in hair.

Note: Often termed "hair follicle tests", the examination evaluates the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Reece City, AL, hair follicle testing surpasses urine tests with its superior 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.
