Hair Follicle Drug Testing - Lillie, LA

What it is, How it works

Hair evaluations have emerged as an effective approach for spotting drug and alcohol consumption. Hair strands capture a longer-term record of alcohol and drug usage by embedding biomarkers within their fibers. When samples are taken near the scalp, hair offers up to an estimated three-month timeframe for drug and alcohol detection. Collecting hair is easy, challenging to tamper with, and convenient to transport.

A 1.5-inch segment composed of around 200 hair strands (roughly the size of a #2 pencil) closest to the scalp yields 100mg of hair, the preferred sample volume for both screening and validation. For tests that are EtG, additional options, or exceed 10 panels, a 150mg sample is advised. We suggest using a jeweler’s scale for measuring the specimen. Should scalp hair be inaccessible, a comparable quantity of body hair can be used. Head hair specifically refers to scalp hair, while body hair includes all other types (e.g., facial, axillary).

Process Overview

Laboratory processing of a drug test result follows four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning sets up the sample in the lab's system. This step ensures the sample is properly sealed and transported, assigns a random Laboratory Accessioning Number (LAN), and completes additional data entry absent from an electronic chain of custody.

Screening quickly checks for drug abuse. Although cost-effective for ruling out drug use for most samples, a positive screen requires confirmation for court admissibility. Presumptive positives from Screening necessitate further validation.

If Screening indicates a presumptive positive, more hair is extracted from the initial sample for further testing. During Extraction, drugs are isolated from hair at lower concentrations than other methods (like urine or oral fluid), making hair testing the most challenging method.

Confirmation of any positive is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are washed before confirmation if needed. The whole processing journey, from Accessioning to Confirmation, follows guidelines under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can uncover drug use for up to 90 days, unlike urine tests with a shorter detection timeframe.
• Hard to deceive: Cheating a hair drug test is extremely difficult, ensuring more precise results.
• Offers historical insights: It can chart drug consumption habits over a period, not merely recent use.

Limitations:

• Cannot detect recent use: Drugs take about 5-7 days to become detectable in hair.
• Expense: Hair drug tests usually cost more than other drug testing alternatives.
• Result variability: Factors like hair color and individual hair growth differences can influence drug metabolite concentrations in hair.

Note: Commonly referred to as "hair follicle tests", the test examines 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.
