Hair Follicle Drug Testing - Olla, LA

What it is, How it works

Hair testing has emerged as a robust method for spotting drug and alcohol intake. Hair captures a lengthy timeline by embedding biomarkers within the fibers of the hair strand as it grows. When obtained near the scalp, hair can offer nearly a 3-month timeframe for detecting alcohol and drugs. It is easy to collect hair, quite hard to tamper with, and convenient to transport.

A 1.5-inch portion of roughly 200 hair strands (comparable to the thickness of a #2 pencil) near the scalp will yield 100mg of hair, which is the perfect amount for both screening and confirmation. For EtG and other tests beyond 10 panels, 150mg is preferred. We suggest using a jeweler’s scale to weigh the specimen. When scalp hair cannot be collected, a similar quantity of body hair may be used. When we say head hair, we mean scalp hair alone. Body hair encompasses all other hair forms (facial, axillary, etc.).

Process Overview

The key stages in lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the primary processing of a sample into the lab's system. It involves ensuring that the sample was appropriately sealed and sent, assigning a random LAN (Laboratory Accessioning Number), and completing any data entry not supplied by an electronic chain of custody framework.

Screening is a preliminary rapid assessment for substances of abuse. While Screening is an economical method to eliminate drug use in most samples, a positive screen must be confirmed for legal admissibility. Samples that demonstrate possible positives in Screening need additional confirmation.

If a sample is deemed possibly positive in Screening, more specimen is taken from the initial collection and readied for Extraction. Here, drugs are retrieved from hair at lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug analysis one of the most challenging techniques to perform.

Confirmation of a positive screening outcome is executed via GC/MS, GC/MS/MS or LC/MS/MS. All samples with tentative positives are cleansed prior to confirmation. The full lab cycle from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair certification and the ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug assessments can reveal drug intake for up to 90 days, unlike urine tests which have a briefer detection span.
• Challenge to manipulate: It is extremely hard to fake a hair drug assessment, ensuring more reliable results.
• Conveys historical insights: It offers a drug use pattern over a period, not merely recent usage.

Limitations:

• Cannot detect recent usage: Drugs require around 5-7 days to appear in hair.
• Expense: Hair drug assessments are typically costlier than other testing approaches.
• Result variations: Elements like hair color and personal hair growth differences can influence drug metabolite concentration in hair.

Note: Even though often called "hair follicle tests", the analysis actually examines the hair strand and not the hair follicle below the scalp.

Why Hair Follicle Testing Beats Urine Testing

Comparing hair follicle and urine tests in Olla, LA reveals clear advantages for the former. Hair testing offers unparalleled detection accuracy and reliability, making it a superior choice for comprehensive screens.

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.
