Hair Follicle Drug Testing - Leeds, AL

What it is, How it works

Hair testing is increasingly regarded as an effective method for identifying drug and alcohol use. Hair captures a comprehensive record of substances, trapping biomarkers within the fibers of its growing strands. When collected near the scalp, hair can offer a detection period of up to around three months for drugs and alcohol. Hair is easy to gather, relatively hard to tamper with, and convenient to send.

A 1.5-inch sample comprising approximately 200 hair strands (roughly the diameter of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal sample for both screening and confirmation processes. For EtG, additional analyses, and/or panels exceeding 10 tests, a 150mg specimen is advisable. It's suggested to weigh the sample using a jeweler’s scale. If scalp hair isn't accessible, an equivalent quantity of body hair may be used. When mentioning head hair, it is specifically scalp hair. Body hair includes other types like facial or axillary hair.

Process Overview

The primary steps in the lab processing of a drug test result involve Accessioning, Screening, Extraction, and Confirmation.

Accessioning marks the initial stage of processing a sample into a lab’s system. This step ensures the sample was correctly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and concludes any data entry not already available through an electronic chain of custody system.

Screening provides an initial rapid test for drugs of abuse. While Screening is cost-efficient for eliminating drug use in most samples, a positive result must be verified for court acceptance. Samples showing presumptive positives in Screening require secondary confirmation.

If Screening indicates a presumptive positive, additional hair is extracted from the initial sample and prepped for the Extraction stage. Here, drugs are drawn from hair at a significantly lower concentration than other methods (like urine or oral fluid), making hair drug screening the most challenging to execute.

Confirmation of positive results is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives are washed before confirmation when necessary. The entire laboratory workflow, from Accessioning to Confirmation, aligns with both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair tests can reveal drug use up to 90 days, unlike urine tests that have a shorter timeframe.
• Hard to invade: Cheating a hair test is nearly impossible, ensuring more accurate results.
• Shows usage history: It illustrates a drug use trend over time, not just recent usage.

Limitations:

• Incapable of detecting recent consumption: Drugs become traceable in hair after about 5-7 days.
• Expense: Hair testing tends to be pricier compared to other testing methods.
• Result variations: Factors like hair color and individual hair growth differences can influence drug metabolite levels in hair.

Note: Although often termed "hair follicle tests", this test evaluates the hair strand, not the 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.
