Hair Follicle Drug Testing - Largo, FL

What it is, How it works

Hair assessments are now regarded as a potent method for identifying drug and alcohol consumption. Hair retains a prolonged record of alcohol and other drugs by embedding biomarkers within the fibers of the hair as it grows. When collected near the base of the scalp, hair can provide a detection timeframe of up to roughly 3 months for alcohol and other drugs. The collection of hair is straightforward, relatively resistant to tampering, and simple to transport.

A 1.5-inch portion comprising about 200 hair strands (comparable to the size of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the ideal sample size for screening and verification. For EtG, additional tests, and/or examinations beyond 10 panels, a 150mg sample is advisable. Utilizing a jeweler’s scale to weigh the sample is recommended. In the absence of scalp hair, an equivalent amount of body hair may be obtained. When referring to head hair, it specifically denotes scalp hair. Body hair encompasses all other types of hair (facial, axillary, etc.).

Process Overview

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

Accessioning pertains to the initial incorporation of a sample into a laboratory’s framework. This process includes ensuring the sample was properly sealed and transported, providing a random LAN (Laboratory Accessioning Number), and finalizing any additional data input absent from an electronic chain of custody system.

Screening consists of a preliminary rapid evaluation for substances of abuse. While Screening is a cost-efficient means to discount drug usage in most samples, a positive screen must be substantiated for court acceptability. Any samples preliminarily positive in Screening require secondary verification.

If a sample tests preliminarily positive during the Screening phase, additional hair is taken from the original sample for Extraction. In this phase, drugs are withdrawn from hair at much lower concentrations than with other methods (ex. urine or oral fluid), making hair drug screening the most challenging technique to execute.

Confirmation of any positive screen is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples showing presumptive positivity are cleansed prior to confirmation as necessary. The entire laboratory activity from Accessioning to Confirmation is conducted in compliance with both the CAP (College of American Pathologists) Hair designation and the accreditation under ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug evaluations can trace drug consumption for as long as 90 days, in contrast to urine tests that have a shorter detection span.
• Difficult to manipulate: Cheating on a hair drug test is notably tough, resulting in more reliable outcomes.
• Tracks usage history: It can depict a pattern of substance usage over time, beyond just recent consumption.

Limitations:

• Cannot detect recent intake: It takes around 5-7 days for substances to become traceable in hair.
• Expense: Hair drug evaluations are typically more costly than other drug testing procedures.
• Result variability: Elements such as hair color and personal variations in hair growth may influence the presence of drug metabolites in the hair.

Note: The procedure commonly referred to as "hair follicle tests" actually examines the hair strand, not the follicle underneath 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.
