Hair Follicle Drug Testing - Murray, IA

What it is, How it works

Hair analysis is considered a potent approach for identifying drug and alcohol consumption. Hair encapsulates a long-term record of drug and alcohol intake by embedding biomarkers within the strands during growth. When procured near the scalp, it can reveal alcohol and drug usage over roughly a 3-month span. Hair collection is straightforward, challenging to falsify, and convenient to transport.

A sample measuring 1.5 inches, consisting of roughly 200 strands (equivalent to a #2 pencil's thickness) near the scalp, yields 100mg of hair, which is optimal for initial testing and subsequent verification. For EtG supplements and/or assays beyond 10 panels, a 150mg specimen is advised. We suggest using a jeweler’s scale for measuring. If scalp hair isn't available, a comparable amount of body hair can be submitted. "Head hair" specifically denotes scalp hair, while "body hair" refers to all other types (facial, underarm, etc.).

Process Overview

The principal stages in laboratory drug test processing include Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample is initially processed into the lab’s system. This phase ensures that the sample was appropriately sealed and transported, assigns a unique LAN (Laboratory Accessioning Number), and finalizes any pending data input not handled by an electronic chain of custody system.

Screening entails an initial scan for abusive substances. Although Screening is cost-efficient for initially ruling out drug use in most samples, positive results from Screening must be confirmed for legal admissibility. Samples preliminarily positive during Screening necessitate further confirmation.

For samples preliminarily positive in Screening, additional hair is extracted from the initial batch for the Extraction process. Drugs are extracted at lower concentrations than in other methods (e.g., urine or oral fluid), which is why hair drug screening is the most complex method to conduct.

Any positive result from Screening is validated using GC/MS, GC/MS/MS, or LC/MS/MS technologies. All samples indicated as positive preliminarily are cleansed before confirmation if required. The comprehensive lab process, from Accessioning to Confirmation, is inspected under both CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug analyses can track drug usage up to 90 days, unlike urine tests which have restricted detection periods.
• Challenging to deceive: Altering a hair drug test is considerably difficult, enhancing result accuracy.
• Delivers historical insights: It offers a record of drug use over time, beyond just recent usage.

Limitations:

• Lacks recent use detection: Drugs only become detectable in hair after around 5-7 days.
• Expense: Hair drug screening tends to be pricier than alternative testing modes.
• Result variability: Elements like hair color and growth rate can influence drug metabolite levels in hair.

Note: Commonly termed "hair follicle tests", the analysis focuses on the hair strand rather than the follicle itself 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.
