Hair Follicle Drug Testing - Cottondale, AL

What it is, How it works

Hair testing has emerged as a potent method for identifying drug and alcohol use. Hair retains a historical record of substance consumption by embedding biomarkers within the growing hair strand's fibers. A sample collected near the scalp can offer up to a 3-month detection timeline for substances. Hair is straightforward to gather, challenging to tamper with, and convenient to transport.

A 1.5-inch segment comprising approximately 200 hair strands (the diameter of a #2 pencil) nearest the scalp yields 100mg of hair, which is ideal for both screening and confirmation. For EtG, add-ons, or tests over 10 panels, 150mg of the sample is advisable. It's best to measure the sample with a jeweler’s scale. Should scalp hair be inaccessible, a comparable amount of body hair may be obtained. When mentioning head hair, we specifically mean scalp hair. Body hair encompasses all other types (e.g., facial, axillary).

Process Overview

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

During Accessioning, the sample first enters the lab system. This step ensures the sample's proper sealing and transporting, assigns a Laboratory Accessioning Number (LAN) randomly, and completes any additional manual data entry not captured by an electronic chain of custody.

Screening is a preliminary assessment for drugs of abuse. Although cost-effective in excluding drug use from most samples, any positive screenings must be confirmed to hold up legally. Samples that test positive during Screening need further confirmation.

If a sample returns presumptively positive in Screening, additional hair is retrieved from the original sample and prepped for Extraction. This stage involves extracting drugs from hair at significantly lower concentrations than alternative methods (e.g., urine, oral fluid), making hair drug screening particularly complex.

The Confirmation phase for any positive screening utilizes GC/MS, GC/MS/MS, or LC/MS/MS. All samples identified as presumptively positive are washed before confirmation as necessary. The full process from Accessioning to Confirmation adheres to CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can reveal drug use for up to 90 days, unlike urine tests which offer a shorter detection span.
• Difficulty to cheat: Cheating a hair drug test is extremely challenging, thereby enhancing result accuracy.
• Provides historical data: It showcases a timeline of drug usage, rather than just recent activity.

Limitations:

• Cannot detect recent use: It takes roughly 5-7 days for drugs to become noticeable in hair.
• Cost: Hair drug tests are typically pricier than other testing options.
• Variations in results: Factors like hair color and individual hair growth rates can influence drug metabolite levels in the hair.

Note: Although often termed "hair follicle tests", the analysis is conducted on the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Cottondale, AL, hair follicle testing stands out against traditional urine tests by offering longer detection periods and greater accuracy.

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.
