Hair Follicle Drug Testing - Rendon, TX

What it is, How it works

Hair strand analysis has emerged as a pivotal instrument for identifying drug and alcohol consumption. The strands encapsulate a long-term record of alcohol and drug use by holding biomarkers within the fibers of continuously growing hair. When gathered closely from the scalp, these strands offer a detection span of as long as three months for alcohol and drug traceability. Hair collection is straightforward, relatively tamper-resistant, and convenient for transportation.

A 1.5-inch snippet comprising around 200 hair strands (comparable to the size of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the prime quantity for both screening and verification. For EtG, additional tests, or assessments exceeding 10 panels, obtaining 150mg of the sample is advisable. We suggest using a jeweler’s scale for specimen measurement. Should scalp hair be absent, a corresponding quantity of body hair can be used. The term head hair refers solely to scalp hair, whereas body hair covers all other hair types (facial, axillary, etc.).

Process Overview

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

Accessioning comprises the preliminary processing of a sample into the laboratory's system, ensuring the sample's sealing and proper shipment, assigning it a random LAN (Laboratory Accessioning Number), and filling in any missing data not supplied by an electronic chain of custody platform.

Screening conducts a swift evaluation for drug abuse. While it's an economical means to dismiss drug use in most samples, any positive indication necessitates confirmation for courtroom admissibility. Any samples indicating presumptive positivity in Screening necessitate additional confirmation.

For samples showing presumptive positivity in the Screening phase, additional hair is extracted from the original sample and prepped for Extraction. In this process, drug compounds are extracted from the hair in notably lower concentrations compared to other methodologies (e.g., urine or oral fluid), rendering hair drug screening the most intricate methodology to undertake.

Confirmation for any positive results from Screening is executed via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation as required. The complete laboratory process, spanning from Accessioning to Confirmation, undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can reveal drug use up to 90 days prior, in contrast to urine tests which offer a shorter timeframe for detection.
• Difficult to compromise: Hair drug tests are arduous to alter, enhancing result accuracy.
• Shows usage patterns: Provides an overview of drug use across time, beyond just recent consumption.

Limitations:

• Incapable of identifying immediate use: Drugs take about 5-7 days to be identifiable in hair.
• Expense: Hair drug tests are frequently costlier compared to alternate drug testing strategies.
• Result variability: Factors like hair color and individual hair growth differences can influence the concentration of drug metabolites in hair.

Note: Despite the term "hair follicle tests", the assessment targets the hair strand, not the sub-surface follicle.

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.
