Hair Follicle Drug Testing - Rex, GA

What it is, How it works

Hair examination has emerged as an effective resource for identifying consumption of drugs and alcohol. Hair offers an extended historical record of substances by embedding biomarkers within the fibers of the growing strand. When collected near the scalp, it can furnish up to a 3-month insight into alcohol and drug use. Hair collection is straightforward, challenging to tamper with, and convenient to transport.

A sample measuring 1.5 inches consisting of approximately 200 hair strands (roughly the size of a #2 pencil) positioned nearest to the scalp yields 100mg, which is the optimal sample for both screening and confirmation. For tests involving EtG, additional panels beyond 10, a sample weighing 150mg is advisable. Utilizing a jeweler’s scale to weigh the sample is recommended. In the absence of scalp hair, an equivalent quantity of body hair can be used. 'Head hair' exclusively refers to scalp hair in this context. 'Body hair' encompasses all other types (facial, axillary, etc.).

Process Overview

The lab procedures for drug test results encompass four principal phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial incorporation of a sample into a lab’s framework. This phase verifies that the sample was properly sealed and dispatched, assigns a unique LAN (Laboratory Accessioning Number), and finalizes any additional data entry absent from an electronic chain of custody system.

Screening provides an initial rapid assessment for drugs. Although it is an economical approach to exclude drug use in most samples, a positive screen requires validation for courtroom admissibility. Any samples that are presumptive positive in Screening necessitate a follow-up confirmation.

Should a sample display a presumptive positive result during Screening, additional hair is extracted from the initial sample and readied for Extraction. During this step, drugs are removed from the hair at far lower levels than observed in other systems (such as urine or oral fluids), underscoring the complexity and rigor of hair drug screening.

Confirmation of any positive screening result is performed using methods such as GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as required. The full laboratory process from Accessioning through to Confirmation adheres to the CAP (College of American Pathologists) Hair standards and complies with ISO / IEC 17025 accreditation criteria.

Advantages of hair drug testing:

• Extended detection window: Drug use can be spotted for up to 90 days, longer than the shorter timeline provided by urine tests.
• Reduced potential for deception: Tampering with a hair drug test is highly improbable, which enhances result reliability.
• Chronological data: Offers insight into patterns of drug use over time, not merely recent consumption.

Limitations:

• Inability to detect recent use: Drugs generally require 5-7 days to become traceable in hair.
• Expense: Hair drug tests tend to be costlier than alternative testing methodologies.
• Result variability: Elements like hair color and individual hair growth can influence the concentration of drug metabolites within hair.

Note: Often called "hair follicle tests", the test actually examines 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.

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