Hair Follicle Drug Testing - Sisters, OR

What it is, How it works

Hair analysis is increasingly recognized as a robust means for uncovering drug and alcohol consumption. Hair captures long-term evidence of substance use by securing biomarkers within the strands as they grow. When obtained near the scalp, hair can reveal drug or alcohol use within an approximate period of 90 days. This method is straightforward to collect, challenging to tamper with, and convenient to transport.

A sample measuring 1.5 inches and consisting of around 200 strands (approximately the girth of a #2 pencil) close to the scalp provides 100mg of hair, ideal for both screening and confirmation. For EtG tests, add-ons, or panels exceeding 10, it's advisable to use 150mg. We suggest weighing the sample using a jeweler's scale. Should scalp hair be unavailable, a comparable amount of body hair is acceptable. When mentioning head hair, it specifically refers to scalp hair, while body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The laboratory procedure for processing drug test outcomes includes four pivotal stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning consists of the preliminary incorporation of a sample into the lab’s system. This process involves ensuring the sample’s appropriate sealing and dispatch, assigning it a unique LAN (Laboratory Accessioning Number), and completing any missing data not supplied electronically.

Screening involves an initial rapid assessment for drugs of abuse. Although cost-efficient for ruling out drug use in most samples, a positive Screening result necessitates confirmation for legal validity. All samples flagged as presumptively positive in Screening require further confirmation.

If a sample is identified as presumptively positive during Screening, additional hair is extracted from the initial sample and prepped for Extraction. At this juncture, drugs are isolated from hair at considerably lower concentrations compared to other methods such as urine or oral fluid, making hair drug screening exceptionally challenging.

For Confirmation, any positive Screening results are verified via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive specimens undergo a washing procedure before confirmation if necessary. The entire laboratory sequence from Accessioning to Confirmation is subject to inspection under the CAP (College of American Pathologists) Hair guidelines and in accordance with ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can recognize drug use up to 90 days, unlike urine tests that offer a shorter detection timeline.
• Difficulty in manipulation: Cheating a hair drug test is highly challenging, thereby enhancing accuracy.
• Historical consumption patterns: It provides insights into drug use trends over time, not merely recent use.

Limitations:

• Incapability to identify recent use: Drugs take about 5-7 days to become detectable in hair.
• Price: Generally, hair drug tests are pricier than alternative drug screening methods.
• Result variability: Factors such as hair color and individual hair growth variations can impact drug metabolite concentrations in hair.

Note: Although colloquially termed "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. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.

Forensic Applications and Interpretation: One of the vital objectives of hair testing is its application in forensic investigations and legal proceedings. The SoHT meeting in Verona emphasized the significance of rigorous interpretation of analytical results and the need for standardized protocols.
