Hair Follicle Drug Testing - Parrottsville, TN

What it is, How it works

Hair analysis has emerged as an effective method for uncovering drug and alcohol consumption. Hair strands capture biomarkers within the growing hair's fibers, offering a lengthy record of alcohol and drug use. A sample taken near the scalp can reveal alcohol and other drugs for a period of up to three months. Hair is easy to gather, hard to tamper with, and simple to mail.

Collecting a 1.5-inch section of around 200 hair strands (comparable to the thickness of a #2 pencil) near the scalp yields 100mg, the preferable amount for both screening and confirmation tests. For tests such as EtG or those over 10 panels, a specimen of 150mg is advised. Using a jeweler’s scale is recommended to measure the specimen weight. If scalp hair is missing, a comparable quantity of body hair may be taken. "Head hair" specifically means scalp hair, while "body hair" encompasses all other types (e.g., facial, axillary).

Process Overview

Processing a drug test result in the lab involves four essential steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the process of integrating a sample into a laboratory's system initially. This step confirms the sample’s proper sealing and shipping, assigns a random LAN (Laboratory Accessioning Number), and completes any extra data input missing from an electronic chain of custody system.

Screening provides an initial evaluation for substance abuse. Screening is cost-efficient for ruling out drug use in most samples, although a positive result requires validation to be court-admissible. Any sample deemed presumptively positive during Screening must undergo Confirmation.

Presumptive positives identified in Screening involve extra hair taken from the original sample for Extraction. Here, drugs are retrieved at concentrations much lower than those in other methods (e.g., urine or oral fluid), making hair drug testing more challenging.

Any positive screen results need GC/MS, GC/MS/MS, or LC/MS/MS Confirmation. All samples with presumptive positives are cleaned beforehand if necessary. The entire lab process is scrutinized from Accessioning to Confirmation under the CAP (College of American Pathologists) Hair designation and complies with ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests reveal drug use for up to 90 days, as opposed to shorter timeframes with urine tests.
• Hard to manipulate: The results of a hair drug test are more reliable due to increased tampering difficulty.
• Gives temporal data: It demonstrates drug consumption trends over time, not just recent usage.

Limitations:

• No recent usage detection: Detecting drugs in hair takes about 5-7 days post-use.
• Expense: Hair drug tests usually cost more than other drug testing approaches.
• Result variability: Factors like hair color and personal hair growth differences can influence drug metabolite concentrations in hair.

Note: Though called "hair follicle tests", the analysis examines the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Parrottsville, TN, hair follicle testing surpasses traditional urine screening by offering enhanced detection accuracy and reliability. Hair tests analyze a longer history, providing a comprehensive picture of substance use, unlike urine tests that only detect recent usage.

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.
