Hair Follicle Drug Testing - Wolfdale, PA

What it is, How it works

Seen as a formidable mechanism, hair testing effectively identifies drug and alcohol consumption. By capturing biomarkers within the fibers of a developing hair strand, hair offers a retrospective account of alcohol and other drug usage. When procured near the scalp, hair can present a detection timeframe of up to roughly three months for alcohol and various drugs. Hair is straightforward to gather, fairly resistant to tampering, and simple to transport.

An ideal screening and confirmation specimen consists of a 1.5-inch segment of roughly 200 hair strands (comparable in size to a #2 pencil) nearest to the scalp, yielding 100mg of hair. For tests such as EtG, add-ons, and/or those over 10 panels, a specimen amounting to 150mg is advisable. We suggest using a jeweler's scale to weigh the sample. In the absence of scalp hair, an equivalent quantity of body hair may be collected. References to head hair exclusively pertain to scalp hair, while body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The lab processing of drug test outcomes encompasses four pivotal steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning describes the initial incorporation of a sample into the lab’s framework. This process involves confirming proper sealing and shipping of the sample, assigning a unique LAN (Laboratory Accessioning Number), and recording supplementary information absent in an electronic chain of custody setup.

Screening constitutes an initial rapid assessment for abusive substances. While this economical approach efficiently excludes drug use in most cases, a positive indication necessitates confirmation for legal acceptance. Samples preliminarily testing positive in Screening must undergo further confirmation.

Upon a presumptive positive result in the Screening phase, additional hair is extracted from the initial sample and prepped for Extraction. In this phase, drugs are derived from hair at significantly lower concentrations compared to alternative techniques (e.g., urine or oral fluid), making hair drug testing the most challenging technique to perform.

GC/MS, GC/MS/MS, or LC/MS/MS methods are used to confirm positive screening findings. Before confirmation, all samples preliminarily positive are washed as required. From Accessioning through Confirmation, the complete laboratory procedure adheres to both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection span: Hair tests expose drug use for up to 90 days, while urine tests offer a shorter detection interval.
• Testing integrity: Cheating a hair drug test is exceedingly difficult, enhancing result accuracy.
• Chronological consumption data: It provides insights into drug use trends over time, rather than only recent usage.

Limitations:

• Inability to confirm recent use: Drug detectability in hair takes around 5-7 days.
• Expense: Hair drug testing typically incurs higher costs than other testing methods.
• Result variability: Hair color and individual hair growth variations can influence drug metabolite concentrations within hair.

Note: Referred to as "hair follicle tests", it's the hair strand tested, 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.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing.
