Hair Follicle Drug Testing - Concordville, PA

What it is, How it works

Hair analysis is widely recognized as an effective method for identifying substance use. Hair strands provide historical data on alcohol and drug consumption by capturing biomarkers within their fibers. When taken from near the scalp, hair offers about a three-month detection period for substances. Its collection is straightforward, it's relatively tamper-proof, and it can be easily transported.

A sample measuring 1.5 inches with approximately 200 hair strands (comparable to the width of a #2 pencil) nearest the scalp results in 100mg, which is the desired quantity for testing. For EtG, specialized tests, and/or analyses beyond 10 substances, a 150mg sample is advised. It's best to weigh the sample using a jeweler’s scale. In the absence of scalp hair, a similar quantity of body hair can be used. When we mention head hair, it refers specifically to scalp hair. Body hair encompasses other hair types (such as facial, axillary, etc.).

Process Overview

There are four primary phases in the lab processing of drug test results: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample is initially processed into the lab’s system, ensuring the sample's seal and shipment were handled correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry not captured by an electronic chain of custody system.

Screening entails a preliminary check for drug abuse substances. Though Screening is an economical approach to discard drug presence in most samples, a positive initial result necessitates verification for legal admissibility. Samples that test positive in Screening require further confirmation.

If a sample tests positive non-definitively during Screening, more hair is retrieved from the initial sample for Extraction. During this phase, substances are extracted from hair at much lower concentrations compared to other methods (such as urine or oral fluid), which explains why hair drug analysis is one of the most intricate methodologies.

Verification of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples assumed positive undergo a pre-confirmation wash as necessary. The entirety of the lab procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair tests can identify drug use up to 90 days back, unlike urine tests which have a shorter timeframe.
• Challenging to deceive: Manipulating a hair test is extremely difficult, enhancing result accuracy.
• Historical use pattern: It reveals a timeline of drug use, not limited to recent consumption.

Limitations:

• Unable to detect recent use: Drugs take approximately 5-7 days to appear in hair.
• Expense: Hair testing typically costs more than other testing methods.
• Result variations: Differences in hair color and personal hair growth rates can impact drug metabolite concentrations in hair.

Note: Although commonly called "hair follicle tests," the analysis is conducted on the hair strand and not the follicle beneath 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.
