Hair Follicle Drug Testing - Flat Rock, NC

What it is, How it works

Hair analysis has gained recognition as an effective means for detecting substance use, both drugs and alcohol. Hair captures a prolonged historical record due to the presence of biomarkers within the fibers of the hair as it grows. When sourced near the scalp, it can reveal up to a three-month timeframe for detecting substances. The collection process for hair is straightforward, relatively resistant to tampering, and convenient to transport.

Procuring a 1.5-inch segment of roughly 200 hair strands (comparable to a #2 pencil's size) located nearest the scalp yields 100mg, which serves as the optimal quantity for screening and verification. For EtG, additional tests, and/or those exceeding 10 panels, 150mg of hair is preferred. It's advised to use a jeweler’s scale for specimen weighing. In cases where scalp hair isn't obtainable, a similar quantity of body hair can suffice. References to head hair pertain solely to scalp hair, while body hair encompasses other types (such as facial or axillary).

Process Overview

The laboratory process for analyzing drug tests consists of four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the preliminary processing of a sample within a lab's framework. This step includes confirming the sample's proper sealing and shipping, allocating a random LAN (Laboratory Accessioning Number), and finalizing any extra data entry absent from an electronic chain of custody system.

Screening entails an initial rapid evaluation for drug presence. Although Screening is economical for excluding drug use in most samples, any positive screen result necessitates confirmation to ensure court admissibility. Presumptive positives in Screening therefore warrant further confirmation.

If a sample emerges as presumptively positive during Screening, additional hair is extracted from the primary specimen and readied for Extraction. Drugs are extracted from hair at significantly reduced concentrations compared to other methods (such as urine or oral fluids). Thus, hair drug analysis is the most challenging methodology to execute.

Confirmation of any positive Screening outcome involves techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive undergo necessary washing before confirmation. From Accessioning to Confirmation, the detailed lab procedure is scrutinized under both the CAP (College of American Pathologists) Hair accreditation and ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extensive detection period: Hair drug assessments identify drug intake for up to 90 days, whereas urine tests have a much shorter window.
• Hard to manipulate: Hair drug tests are incredibly resistant to tampering, ensuring result accuracy.
• Offers usage insights: It reveals usage patterns over time, not just recent consumption.

Limitations:

• Lacks recent usage detection: Drugs take around 5-7 days to manifest in hair.
• Expense: Generally, hair drug tests cost more than alternative methods.
• Result variability: Factors such as hair shade and individual hair growth rates can influence drug metabolite concentrations in hair.

Note: Commonly termed "hair follicle tests", the analysis focuses on the hair strand and not the underlying scalp follicle.

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.
