Hair Follicle Drug Testing - Jamestown, NC

What it is, How it works

Hair testing is recognized as an effective method for detecting drug and alcohol consumption. Hair captures a long-term record of alcohol and substances by securing biomarkers within the hair strand's fibers. Collected near the scalp, hair offers nearly a 3-month detection period for alcohol and drugs. It's easy to collect, harder to deceive, and simple to send.

To obtain the optimal sample of 100mg for analysis, a 1.5-inch section of roughly 200 hair strands (similar to a #2 pencil's size) from near the scalp is needed. For EtG, additional tests, or those above 10 panels, 150mg of sample is preferred. Using a jeweler’s scale is advised for weighing the sample. If scalp hair is not accessible, an equivalent amount of body hair can be used. "Head hair" refers exclusively to scalp hair. "Body hair" includes all other hair types (facial, axillary, etc.).

Process Overview

The laboratory steps for processing a drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning starts with entering a sample into a lab's system. This step checks proper sealing and shipping of the sample, allocates a random LAN (Laboratory Accessioning Number), and finishes any missing data entry not provided by an electronic chain of custody system.

Screening is an initial quick evaluation for drug abuse. Although it's cost-effective for excluding drug usage in many samples, a positive screen needs confirmation for court acceptance. Samples with a presumptive positive in Screening require further confirmation.

For samples deemed presumptively positive during Screening, additional hair is extracted from the initial sample for Extraction. Here, drugs are taken from hair at much lower concentrations than in methods like urine or oral fluid, making hair drug testing the toughest methodology.

Positive screening results are confirmed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples marked as presumptive positive undergo a wash before needed confirmation. The entire lab process from Accessioning to Confirmation is evaluated under both CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Benefits of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use for up to 90 days, unlike urine tests that have a shorter detection period.
• Hard to cheat: It's very challenging to manipulate a hair drug test, resulting in more precise outcomes.
• Historical data: It offers a drug usage pattern over time, not just recent usage.

Drawbacks:

• Cannot detect recent use: It takes about 5-7 days for drugs to appear in hair.
• Expense: Hair drug tests tend to be costlier than other drug testing techniques.
• Result variations: Aspects like hair color and individual hair growth differences can influence drug metabolite concentration in hair.

Note: Despite being called "hair follicle tests," the test examines the hair strand, not the follicle under the scalp

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.

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis.
