Hair Follicle Drug Testing - Devault, PA

What it is, How it works

Hair analysis has become recognized as an effective method for identifying drug and alcohol consumption. Hair captures a comprehensive record of alcohol and other drug use by embedding biomarkers within the hair as it grows. When taken near the scalp, hair samples can reveal drug and alcohol use over a period of up to 90 days. Collecting hair is straightforward, challenging to tamper with, and convenient to transport.

A 1.5-inch sample consisting of roughly 200 hair strands (approximately the thickness of a #2 pencil) closest to the scalp yields 100mg of hair, a perfect quantity for both screening and confirmation. For tests like EtG, add-ons, and beyond 10 panels, a specimen of 150mg is suggested. It's advisable to weigh the sample using a jeweler's scale. If scalp hair is not available, a comparable quantity of body hair can be used. By head hair, only scalp hair is meant. Body hair encompasses all other categories (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result includes four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning deals with the initial integration of a sample into a laboratory's system. This step involves ensuring the sample was properly sealed and dispatched, assigning it a random LAN (Laboratory Accessioning Number), and fulfilling any extra data entry that an electronic chain of custody system does not provide.

Screening acts as an initial rapid evaluation for drug use. Although Screening is a cost-efficient approach to exclude drug usage in most samples, a positive screening result must be validated for legal acceptability. Any samples that test preliminarily positive during Screening call for a secondary confirmation.

When a sample tests preliminarily positive in the Screening stage, additional hair is taken from the original specimen for Extraction preparation. During this phase, drugs are extracted from the hair at lower concentrations than other methods (such as urine or oral fluid), marking hair drug screening as the most challenging methodology to execute.

Positive screening results undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, presumptive positive samples are washed as necessary. The comprehensive laboratory workflow from Accessioning through to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair designation and conformance to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can reveal drug usage up to 90 days prior, whereas urine tests feature a limited detection timeline.
• Hard to manipulate: It is notably difficult to mask a hair drug test, leading to higher accuracy in results.
• Reveals usage trends: It can trace patterns of drug use over a duration, not just recent instances.

Limitations:

• Inability to detect recent intake: Drugs typically require around 5-7 days to be detectable in hair.
• Expense: Hair drug testing tends to be pricier compared to other testing techniques.
• Variation in findings: Variables such as hair color and personal growth differences can influence the presence of drug metabolites in the hair.

Note: Although often termed "hair follicle tests", the analysis actually focuses on the hair strand rather than the follicle below 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.
