Hair Follicle Drug Testing - Warm Springs, GA

What it is, How it works

Hair analysis has gained recognition as a potent mechanism for identifying drug and alcohol usage. Hair strands offer a prolonged record of substances due to the encapsulation of biomarkers within the hair fibers as they grow. When collected from near the scalp, hair can offer a detection period of up to around 3 months for both alcohol and other drugs. The collection of hair is straightforward, not easily tampered with, and can be conveniently shipped.

A 1.5-inch segment comprising roughly 200 hair strands (approximately the size of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal quantity for both screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, a collection of 150mg is advisable. It is suggested to weigh the specimen using a jeweler’s scale. If scalp hair cannot be obtained, a comparable quantity of body hair may be used instead. When mentioning head hair, we strictly refer to scalp hair. In contrast, body hair encompasses other hair forms (such as facial or axillary hair).

Process Overview

The primary stages in the laboratory analysis of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial incorporation of a sample into a laboratory’s operations. This step includes ensuring the sample was correctly sealed and dispatched, allocating a random LAN (Laboratory Accessioning Number), and fulfilling additional data input missing from an electronic chain of custody framework.

Screening is an initial rapid assessment for signs of drug abuse. While Screening efficiently excludes drug use in most samples, any positive result must be confirmed for legal acceptance. Samples that preliminarily test positive in Screening necessitate secondary validation.

Should a sample yield a presumptive positive in the Screening phase, more hair is extracted from the original sample to prepare for Extraction. In this phase, drugs are sourced from hair at a significantly lower density than other techniques (such as urine or oral fluid), rendering hair drug screening the most challenging methodology to execute.

Confirmation of any preliminary positive results from screening is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples undergo washing as necessary. The complete laboratory process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair classification and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection span: Hair drug tests detect drug usage for up to 90 days, unlike urine tests that exhibit a shorter detection period.
• Hard to manipulate: Manipulating a hair drug test is extremely challenging, enhancing the accuracy of the results.
• Offers chronological data: Analyzes can reveal a pattern of drug consumption over a timeframe, not merely recent use.

Limitations:

• Lacks immediate detection: Drugs only become detectable in hair around 5-7 days post-use.
• Expense: Generally, hair drug tests cost more compared to alternative testing methods.
• Results variability: Elements like hair color and personal growth rates can influence drug metabolite concentration in hair strands.

Note: Even though it is frequently termed a "hair follicle test", the analysis is conducted on the hair strand, not on the follicle located 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.
