Hair Follicle Drug Testing - Greenwood, MS

What it is, How it works

Hair testing is recognized as an effective method for detecting substance use. Hair retains a history of alcohol and drug activity by embedding markers within its growing fibers. Sampling near the scalp yields a nearly 3-month detection period for alcohol and substances. This method is straightforward to collect, hard to tamper with, and convenient for shipping.

A 1.5-inch segment comprising around 200 hair strands (roughly the diameter of a #2 pencil) next to the scalp amounts to 100mg of hair, an ideal sample for screening and verification. For EtG, additional tests, and/or panels exceeding 10, a 150mg specimen is advised. We suggest utilizing a jeweler’s scale for specimen weighing. In cases where scalp hair is unavailable, an equivalent quantity of body hair is acceptable. Scalp hair refers exclusively to head hair, whereas body hair denotes all other types (facial, axillary, etc.).

Process Overview

The principal phases in laboratory processing of drug test results comprise Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the preliminary integration of a sample into a lab's system, which involves verifying correct sealing and shipping of the sample, allocating a random LAN (Laboratory Accessioning Number), and filling in any absent data not covered by an electronic chain of custody system.

Screening represents an initial, cost-efficient check for substance abuse indicators. Although effective for ruling out drugs in numerous samples, a positive screen demands confirmation to stand in legal proceedings. All samples initially testing positive in Screening necessitate further confirmation.

Samples presumed positive in the Screening phase prompt additional hair extraction from the initial sample for preparation in the Extraction stage. Here, drugs are isolated from hair at significantly lower concentrations than in other methods (e.g., urine or oral fluid), making hair drug screening highly challenging to execute.

Confirming a positive screening outcome occurs through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing prior to confirmation if necessary. The comprehensive laboratory operation from Accessioning to Confirmation is evaluated in accordance with CAP (College of American Pathologists) Hair classification and accreditation to ISO / IEC 17025 standards.

Benefits of hair drug testing:

• Extended detection period: Hair drug tests extend drug use detection up to 90 days, versus the shorter timeframe of urine tests.
• Hard to manipulate: Cheating a hair drug test is highly challenging, ensuring result accuracy.
• Reveals usage patterns: It delineates drug use patterns over extended periods, not merely recent consumptions.

Drawbacks:

• Incapaable of recent detection: Detecting drugs in hair entails roughly 5-7 days before becoming evident.
• Expense: Hair drug tests often cost more than alternative testing approaches.
• Outcome discrepancies: Variables like hair color and individual growth differences can influence drug metabolite concentrations in hair.

Note: Although frequently termed as "hair follicle tests", the actual assessment targets 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.
