Hair Follicle Drug Testing - Dunbarton, LA

What it is, How it works

Hair testing is recognized as an effective technique for identifying drug and alcohol consumption. Hair offers a prolonged timeline of alcohol and drug evidence by encapsulating biomarkers within the hair strand as it grows. When collected near the scalp, hair can present approximately a three-month detection timeframe for substances. Hair collection is straightforward, somewhat resistant to tampering, and simple to transport.

A 1.5-inch section of roughly 200 hair strands (comparable to the diameter of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the preferred sample amount for analysis and verification. For EtG, add-ons, and/or assessments exceeding 10 panels, 150mg is suggested. Using a jeweler's scale to weigh the specimen is advisable. If scalp hair cannot be obtained, an equivalent amount of body hair is permissible. When mentioning head hair, we mean scalp hair exclusively. Body hair encompasses all other kinds (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result encompasses four key phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the primary processing of a sample into the laboratory system. This stage involves checking that the sample is properly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and performing any additional data input not covered by an electronic chain-of-custody procedure.

Screening starts with a preliminary swift assessment for drugs of abuse. Although Screening is an economical approach to eliminate drug use in most samples, a positive screen must be substantiated for legal acceptability. Samples with presumptive positive in Screening necessitate subsequent validation.

If a sample yields a presumptive positive result during the Screening phase, additional hair is extracted from the initial sample and readied for Extraction. At this stage, drugs are distilled from hair at a substantially reduced concentration compared to other methods (e.g., urine or oral fluid), which is why hair drug testing is the most challenging methodology.

Confirmation of any positive screening outcome is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. Samples marked as presumptive positive undergo washing before confirmation as necessary. The complete lab process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Prolonged detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests with shorter detection intervals.
• Resistant to tampering: Cheating a hair drug test is extremely challenging, enhancing result accuracy.
• Shows historical usage: It can reveal a timeline of drug use over duration, not just recent consumption.

Limitations:

• Unable to detect recent usage: Drugs become detectable in hair about 5-7 days post-use.
• Higher cost: Hair drug tests typically carry a higher price tag compared to alternative testing approaches.
• Variability in outcomes: Hair color and individual differences in hair growth can influence drug metabolite levels in the hair.

Note: Though often termed "hair follicle tests", the analysis evaluates the hair strand, 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.
