Hair Follicle Drug Testing - Clarkson, MS

What it is, How it works

Hair analysis is now recognized as an effective method for identifying drug and alcohol consumption. Hair retains alcohol and drug biomarkers within its fibers, offering an extended historical view. Collected near the scalp, hair reveals a detection period for alcohol and drugs of up to around three months. It is straightforward to gather, challenging to tamper with, and straightforward for shipping.

A 1.5-inch portion comprising about 200 hair strands (approximately the diameter of a #2 pencil) nearest the scalp yields 100mg, the ideal dosage for both screening and verification. For EtG, supplementary tests, and/or tests involving more than ten panels, a specimen of 150mg is suggested. Using a jeweler’s scale is recommended for measuring the specimen. If scalp hair is absent, an equivalent amount of body hair can be used. When we mention head hair, we specifically mean scalp hair. By "body hair," we mean all other forms of hair (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result encompasses four main phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the beginning phase where a sample is initially processed into the lab's system. This step includes confirming that the sample was properly sealed and dispatched, allocating a random LAN (Laboratory Accessioning Number), and completing any necessary data entry absent from an electronic chain of custody system.

Screening is an initial rapid assessment for drug abuse. While Screening acts as a cost-effective measure to exclude drug usage across most samples, a positive outcome in the screening stage requires confirmation for legal admissibility. Samples with preliminary positive results in Screening need a secondary verification.

Should a sample show positive results during the Screening stage, additional hair is taken from the initial specimen for the Extraction process. In this step, drugs are extracted from hair at notably lower concentrations than in other techniques (such as urine or oral fluid), highlighting the complexity of hair drug testing.

The Confirmation phase for any positive Screening results is executed using techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. All samples with preliminary positive results are cleansed before confirmation as required. The entire laboratory procedure from Accessioning to Confirmation is assessed under the CAP (College of American Pathologists) Hair designation and adheres to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests with a shorter duration.
• Hard to manipulate: Altering results in a hair drug test is almost impossible, ensuring greater accuracy.
• Shows usage patterns: Offers insight into drug use patterns over time, beyond the immediate past.

Limitations:

• Recent use undetectable: Hair requires roughly 5-7 days post-use for drugs to be traceable.
• Expense: Hair drug testing generally incurs higher costs than other methods.
• Result variability: Elements such as various hair colors and individual differences in hair growth rate can affect drug metabolite concentration.

Note: Despite being sometimes termed as "hair follicle tests", the analysis focuses on the hair strand rather than 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.
