Hair Follicle Drug Testing - Littleton, NC

What it is, How it works

Hair screening is recognized as a compelling means to uncover drug and alcohol use. Hair strands capture a prolonged record of substances by holding biomarkers inside the strands' fibers as they grow. When taken close to the scalp, hair can offer a detection time frame of roughly 3 months for alcohol and drugs. Hair collection is straightforward, difficult to tamper with, and easy to transport.

Collecting a 1.5-inch section of around 200 hair strands (roughly the thickness of a #2 pencil) nearest to the scalp will yield 100mg of hair, the optimal amount for evaluation and validation. For EtG and other additional tests beyond 10 panels, 150mg of the sample is advised. It's advisable to measure the sample using a jeweler’s scale. If scalp hair isn't accessible, an equivalent quantity of body hair can be used. Scalp hair refers strictly to hair on the head, while body hair encompasses all other forms (like facial, axillary, etc.).

Process Overview

The drug test result processing at the laboratory comprises four key steps: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample is first entered into the laboratory’s workflow. This step involves confirming the sample was sealed and sent correctly, issuing a random LAN (Laboratory Accessioning Number), and completing any additional data entry that wasn’t supplied by an electronic chain of custody system.

Screening serves as an initial evaluation to check for drug presence. Although Screening is an economical method to discount drug usage in most samples, a positive result calls for confirmation to be legally valid. Solid screens that show potential positivity need a follow-up confirmation.

In Screening, if a potential positive is identified, additional hair is extracted from the original sample and processed for Extraction. This phase involves pulling drugs from hair at significantly lower concentrations than found in other methods (like urine or oral fluid), which accounts for why hair screening is a challenging task.

Confirmation of any positive screen outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS. To ensure accuracy, all samples suggesting positivity are cleaned prior to confirmation. The thorough laboratory progression from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair guidelines and the ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Prolonged detection period: Hair drug investigations can identify use for up to 90 days, unlike shorter-period urine tests.
• Challenge to compromise: Hair drug assessments are notably hard to tamper with, leading to more precise outcomes.
• Tracks historical patterns: It can highlight trends of substance use over time, rather than just recent activity.

Limitations:

• Inability to indicate recent use: Drugs require about 5-7 days to become detectable in hair.
• Expense: Hair drug analyses tend to be costlier than other testing approaches.
• Result inconsistencies: Variability due to hair color and personal hair growth rates can impact drug metabolite levels in hair.

Note: Though often labeled "hair follicle tests", the analysis targets the hair strand itself and not the follicle under the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Littleton, NC, hair follicle testing surpasses urine testing by providing unparalleled detection 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.
