Hair Follicle Drug Testing - Melrose, NM

What it is, How it works

The use of hair testing has emerged as a significant method for detecting substance and alcohol consumption. Hair retains a long-term record of alcohol and other substances by embedding biomarkers in the strands as they grow. When sourced near the scalp, hair can offer a detection span for alcohol and other drugs of up to roughly three months. The collection of hair is straightforward, not easily tampered with, and convenient for shipment.

A sample of approximately 1.5 inches comprising about 200 hair strands (comparable to the girth of a #2 pencil) nearest to the scalp yields 100mg of hair, the perfect amount for screening and verification. For tests involving EtG, additional components, and/or panels beyond 10, a sample of 150mg is advised. It's suggested to weigh the sample on a jeweler’s scale. Should scalp hair be unavailable, an equal volume of body hair can be used. Reference to head hair pertains solely to scalp hair. Body hair encompasses all other hair categories (facial, axillary, etc.).

Process Overview

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

Accessioning entails the initial integration of a sample into a lab's system. This step includes confirming that the sample was properly sealed and shipped, assigning it a random LAN (Laboratory Accessioning Number), and finalizing any further data entry not facilitated by an electronic chain of custody system.

Screening consists of an initial, rapid assessment for substance abuse. Although Screening provides a cost-efficient means to eliminate drug use for most samples, a positive screen still requires confirmation for legal admissibility. All samples that show positive indications during Screening must undergo secondary confirmation.

Samples that test presumptively positive during the Screening phase require additional hair from the original specimen for Extraction preparation. This stage involves extracting drugs from hair at concentrations much lower than other methods (e.g., urine or oral fluid), explaining why hair drug screening is among the most challenging techniques.

Confirming any positive screening result is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are washed before confirmation if necessary. The full laboratory workflow from Accessioning to Confirmation is inspected under both the CAP (College of American Pathologists) Hair guideline and accreditation to ISO / IEC 17025 principles.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug consumption for up to 90 days, in contrast to urine tests with a shorter detection timeframe.
• Hard to manipulate: Cheating on a hair drug test is exceedingly difficult, enhancing result accuracy.
• Offers historical insight: It can outline a timeline of substance use over a duration, rather than only recent usage.

Limitations:

• Inability to detect recent use: Detection of drugs in hair typically requires 5-7 days.
• Expense: Hair drug tests are typically costlier than alternative drug testing techniques.
• Result variances: Aspects such as hair color and personal differences in hair growth can influence the levels of drug metabolites in hair.

Note: Although commonly called "hair follicle tests", the test evaluates 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.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented.
