Hair Follicle Drug Testing - Mcgrath, AK

What it is, How it works

Hair examinations have emerged as a robust method for identifying alcohol and drug usage. Hair captures a long-term record of these substances by embedding biomarkers within the fibers of the growing hair. When cut near the scalp, hair can offer a detection period of up to roughly three months for alcohol and drugs. Collecting hair is straightforward, challenging to tamper with, and convenient to transport.

A 1.5-inch segment of roughly 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp will provide 100mg of hair, which is optimal for testing and verifying. For EtG, additional tests, or those exceeding 10 panels, a 150mg sample is advisable. It's suggested to measure the sample using a jeweler's scale. In the absence of scalp hair, a comparable quantity of body hair can be used. When referring to head hair, this specifically indicates scalp hair. Body hair encompasses all other types (e.g., facial, underarm, etc.).

Process Overview

The key stages in the lab analysis of drug test samples are Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary processing of a sample into the lab's system. This process verifies that the sample was correctly sealed and dispatched, assigns a unique LAN (Laboratory Accessioning Number), and completes any extra data inputs not covered by an electronic custody chain system.

Screening provides a preliminary assessment for drug presence. While it is an economical approach to dismiss drug use for most samples, any positive result from Screening needs confirmation to be valid for court proceedings. Any samples that test as supposed positives in Screening require further confirmation.

If a sample suggests positivity in the Screening phase, additional hair is extracted from the primary sample and readied for Extraction. In this phase, drugs are extracted at much lower concentrations than other techniques (e.g., urine or saliva), which makes hair drug analysis the most complex method to conduct.

GC/MS, GC/MS/MS, or LC/MS/MS methods are used for Confirmation of any positive Screening outcomes. All presumptive positives are thoroughly washed before confirmation if required. The full lab process, from Accessioning to Confirmation, undergoes evaluation under both the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug analysis can identify drug usage for up to 90 days, unlike urine tests which have a briefer detection period.
• Difficult to manipulate: Cheating a hair drug test is notably challenging, ensuring higher accuracy of results.
• Offers historical insights: It can illustrate a pattern of substance use over a duration, not solely recent usage.

Limitations:

• Inability to detect recent usage: It requires about 5-7 days for drugs to appear in hair.
• Expense: Hair drug tests typically cost more than other testing methods.
• Result variability: Elements such as hair color and personal differences in hair growth can impact drug metabolite concentrations in the hair.

Note: Although commonly termed as "hair follicle tests", the procedure examines the hair strand itself 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.
