Hair Follicle Drug Testing - Walkers Mill, PA

What it is, How it works

Hair testing is recognized as an effective method for detecting drug and alcohol consumption. Hair captures a detailed history of drug and alcohol use by embedding biomarkers within the fibers of the hair as it grows. When collected from near the scalp, hair offers a detection period of up to three months for drugs and alcohol. It's easy to collect, challenging to tamper with, and simple to transport.

A 1.5-inch segment consisting of about 200 hairs (approximately the thickness of a #2 pencil) harvested close to the scalp provides 100mg of hair, the ideal amount for both screening and confirmation. For EtG, additional tests, and tests beyond 10 panels, 150mg is preferable. It's advisable to weigh the sample with a jeweler’s scale. In the absence of scalp hair, an equivalent quantity of body hair can be used. When we mention head hair, it specifically refers to scalp hair. Body hair encompasses all other types (face, armpits, etc.).

Process Overview

The four primary stages in lab processing for drug testing results are Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves incorporating the sample into the lab's system, ensuring that it's properly sealed and delivered, assigning it a random LAN (Laboratory Accessioning Number), and completing any data entry not captured by an electronic chain of custody system.

Screening is a preliminary assessment to check for drug traces. While it's a cost-efficient way to eliminate drug usage in most samples, a positive result requires confirmation for court admissibility. Samples that are presumptively positive during Screening require further confirmation.

If a sample shows presumptive positivity in Screening, additional hair is extracted from the initial sample and processed for Extraction. Here, drugs are removed from hair at concentrations much lower than other methods (e.g., urine or oral fluids), which is why hair testing is among the most complex methodologies.

Confirmation of a positive screening result is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. Samples deemed presumptively positive undergo washing prior to confirmation as necessary. The entire laboratory process from Accessioning to Confirmation is certified under both CAP (College of American Pathologists) Hair accreditation and ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can identify drug use for up to 90 days, unlike urine testing which has a shorter timeframe.
• Challenging to falsify: The results of a hair drug test are highly reliable due to its resistance to cheating.
• Offers historical insight: It reveals long-term drug use patterns instead of just recent activity.

Limitations:

• Lacks recent usage detection: It takes around 5-7 days for drugs to become evident in hair.
• Expense: Hair drug testing tends to be pricier compared to other methods.
• Result variability: Factors like hair color and individual hair growth rates can influence drug metabolite concentration in hair.

Note: Although often termed "hair follicle tests", the procedure actually evaluates the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Walkers Mill, PA, hair follicle testing offers superior advantages over traditional urine analysis. Accuracy is a crucial factor, as hair tests provide a detection window covering up to 90 days.

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.
