Hair Follicle Drug Testing - Monticello, LA

What it is, How it works

Hair testing is regarded as an effective means for identifying drug and alcohol consumption. Hair captures long-term usage evidence of substances by embedding markers within the fibers of the growing hair. When collected near the scalp, it provides up to a roughly 3-month timeframe for detecting alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and easy to transport.

A 1.5-inch segment of about 200 hair strands (approximate diameter of a #2 pencil) nearest to the scalp yields 100mg, which is the optimal amount for initial screening and verification. For EtG, add-ons, and tests beyond 10 panels, 150mg is advised. It's best to measure the specimen on a jeweler’s scale. In the absence of scalp hair, a similar quantity of body hair is acceptable. When mentioning head hair, it strictly means scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The four core stages in laboratory processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial processing of a sample within a laboratory’s system, which includes confirming the sample was sealed and shipped correctly, generating a random LAN (Laboratory Accessioning Number), and completing any extra data entry not provided by an electronic chain of custody method.

Screening involves a preliminary quick assessment for drugs of abuse. Although Screening is a cost-effective strategy to exclude drug use in most samples, a positive result requires confirmation for court admissibility. Any samples with a presumptive positive result in Screening need a secondary confirmation.

When a sample shows a presumptive positive in Screening, more hair is extracted from the initial sample and prepared for Extraction. Drugs are extracted from hair at significantly lower concentrations than in other methodologies (e.g., urine or saliva), making hair drug screening the most challenging technique to execute.

Confirmation of a positive screening result is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo washing before confirmation as needed. The entire lab process from Accessioning to Confirmation is reviewed under the CAP (College of American Pathologists) Hair designation and accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use up to 90 days, unlike urine tests, which have a shorter detection period.
• Difficulty in manipulation: Manipulating a hair drug test is highly challenging, thus ensuring accurate results.
• Historical usage evidence: It offers a usage pattern over time, not just recent consumption.

Limitations:

• Inability to detect recent usage: Drugs take 5-7 days to become detectable in hair.
• Cost factor: Hair drug tests tend to be pricier than alternative drug testing techniques.
• Variability in outcomes: Factors like hair color and individual hair growth differences can influence drug metabolite levels in hair.

Note: Although sometimes referred to as "hair follicle tests", the analysis targets the hair strand and not the hair 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. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis. The impact of hair treatments on the oxidation/decomposition of drugs in hair was also explored, as the long-term fate of drugs incorporated in the keratin matrix. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.
