Hair Follicle Drug Testing - Brooks, MN

What it is, How it works

The identification of drug and alcohol consumption has been greatly enhanced through hair testing. Hair preserves chemical indicators of alcohol and various drugs within the strands as they grow, offering a comprehensive account over an extended period. When strands are taken near the scalp, they can reveal drug use for a span of nearly 90 days. Hair sampling is straightforward, challenging to tamper with, and convenient to transport.

To obtain the best specimen for testing, a 1.5-inch section consisting of roughly 200 hairs (similar in diameter to a #2 pencil) from the scalp is needed to achieve 100mg. For specific tests such as EtG or those exceeding 10 panels, 150mg is advised. Utilizing a jeweler's scale for measurement is suggested. If scalp hair isn't available, equivalent body hair can be used instead. Herein, “head hair” signifies scalp hair alone, while “body hair” encompasses all other varieties (beard, armpits, etc.).

Process Overview

The laboratory procedure for processing a drug test result encompasses four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning begins the process by integrating the sample into the lab’s system, ensuring the sample is securely sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and handling additional data entry missing from an electronic chain of custody.

Screening performs a preliminary and economical evaluation for drug presence. While effective at excluding drug usage, a positive outcome requires confirmation for court admissibility. Samples with initial positive indications in Screening must undergo a secondary verification.

For samples that test presumptively positive during Screening, further hair is taken from the original source for the Extraction phase. This step isolates drugs at much lower concentrations compared to other test types (e.g., urine or saliva), making hair drug analysis a more intricate testing option.

Positive screening results undergo validation through GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmatory tests, presumptive positive samples are cleaned as necessary. The lab's entire process, spanning from Accessioning to Confirmation, is subject to review under both the CAP (College of American Pathologists) Hair category and ISO/IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair tests can reveal drug use for up to 90 days, surpassing shorter detection periods of urine tests.
• Hard to falsify: Hair drug tests are significantly challenging to manipulate, enhancing accuracy.
• Tracks usage history: They display drug consumption trends over time, not just recent usage.

Limitations:

• Inability to detect recent consumption: Drugs need about 5-7 days before they show in hair.
• Higher expense: Hair tests tend to cost more than alternate methods.
• Result disparities: Elements like hair hue and personal hair growth variability can influence drug metabolite levels in hair.

Note: Although labeled as "hair follicle tests," the analysis is conducted on the hair shaft, not the follicle beneath the skin.

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.
