Hair Follicle Drug Testing - Twin, AL

What it is, How it works

Hair analysis is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair serves as a long-term archive for substances, capturing biomarkers within the strands as the hair grows. When cut near the scalp, hair offers a detection range of up to around three months for identifying drugs and alcohol. Collecting hair is straightforward, relatively resistant to tampering, and convenient for shipping.

Taking a 1.5-inch sample of roughly 200 hair strands (similar to the thickness of a #2 pencil) near the scalp yields 100mg, which is the optimal amount for screening and confirmation. For EtG, add-ons, and/or tests beyond 10 panels, a specimen amount of 150mg is advised. Using a jeweler’s scale to weigh the sample is suggested. In the absence of scalp hair, a similar quantity of body hair can be gathered. In reference to head hair, it specifically denotes scalp hair. Body hair encompasses other types (facial, axillary, etc.).

Process Overview

There are four key steps in the laboratory handling of a drug test result: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step of incorporating a sample into a laboratory's workflow. This step involves checking that a sample is sealed and transported correctly, assigning a unique LAN (Laboratory Accessioning Number), and completing any requisite data entry absent from an electronic chain of custody system.

Screening entails a preliminary assessment for substances of abuse. While Screening efficiently eliminates drug usage in most samples at a lower cost, any positive results need confirmation for legal admissibility. Samples that are characterized as presumptively positive from Screening necessitate further confirmation.

Should a sample be presumptively positive during Screening, more hair is extracted from the original sample and prepared for Extraction. This step involves isolating drugs from hair in lower concentrations than other methods (e.g., urine or oral fluid), which renders hair drug testing particularly challenging.

Confirmation of any positive Screening outcome is achieved via GC/MS, GC/MS/MS, or LC/MS/MS. All samples deemed presumptive positive undergo washing prior to confirmation if necessary. Each phase from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and conformity with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Prolonged detection period: Hair drug tests can identify drug consumption up to 90 days, whereas urine tests have a shorter detection span.
• Challenging to falsify: Cheating a hair drug test is notably difficult, enhancing result accuracy.
• Generates historical insight: It uncovers a timeline of drug usage over months, unlike tests for recent use.

Limitations:

• Incapable of detecting recent consumption: Drugs typically become detectable in hair approximately 5-7 days post-use.
• Expense: Hair drug tests tend to be pricier than alternative drug testing approaches.
• Result variability: Individual factors like hair color and growth rates can influence metabolite concentrations in hair.

Note: Frequently termed "hair follicle tests", these tests analyze the hair shaft and not the hair 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.
