Hair Follicle Drug Testing - Fayette, IA

What it is, How it works

Hair analysis is now recognized as an effective method for identifying drug and alcohol consumption. Hair serves as a long-term record of alcohol and drug exposure by embedding biomarkers within the fibers of the developing hair shaft. When gathered near the scalp, hair can offer a detection timeframe of up to roughly three months for detecting alcohol and drugs. The collection of hair is straightforward, somewhat challenging to tamper with, and simple to transport.

A sample measuring 1.5 inches, comprising around 200 hair strands (approximately matching the thickness of a #2 pencil) closest to the scalp, provides 100mg of hair, which is the optimal amount for evaluation and verification. For testing EtG, any additional options, and/or assays beyond 10 panels, it is advisable to use 150mg of the sample. We suggest using a jeweler’s scale to measure the sample weight. If scalp hair is not available, an equivalent quantity of body hair can be used. The term "head hair" specifically refers to scalp hair only. The term "body hair" encompasses all other types (such as facial and axillary hair).

Process Overview

The laboratory drug testing procedure mainly consists of four steps: Accessioning, Screening, Extraction, and Confirmation.

The Accessioning phase includes the initial incorporation of a sample into a lab’s database. This step involves checking that the sample is securely sealed and transported correctly, assigning an arbitrary LAN (Laboratory Accessioning Number), and finalizing any remaining data input not supported by an electronic chain of custody mechanism.

During Screening, a rapid preliminary check for any substance misuse is performed. Although Screening offers a cost-efficient method to exclude drug intake for most samples, a verified result is necessary for legal admissibility. Samples presumed positive in Screening demand a secondary validation.

When a sample is flagged as presumptively positive during the Screening phase, additional hair is taken from the original sample for the Extraction stage. At this phase, substances are isolated from hair at considerably lower concentrations compared to other techniques (such as urine or oral fluids), highlighting the complexity of performing hair drug testing.

Confirmation of any positive results from Screening is executed using techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo a cleansing before confirmation as needed. The entire testing procedure, from Accessioning to Confirmation, is conducted in accordance with both the CAP (College of American Pathologists) Hair criteria and ISO/IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug evaluations can identify drug use for as long as 90 days, unlike urine tests, which offer a shorter timeline.
• Minimal chance of cheating: Hair drug evaluations are very challenging to manipulate, ensuring more reliable outcomes.
• Historical consumption data: These tests can indicate a pattern of drug usage over time, beyond recent intake.

Limitations:

• Lack of recent use detection: It generally takes 5-7 days for drugs to become identifiable in hair samples.
• Higher cost: Hair drug evaluations are typically pricier than other testing techniques.
• Result variations: Factors such as individual hair color and growth differences may impact the drug metabolite concentrations in hair.

Note: While commonly referred to as "hair follicle tests," these analyses target the hair strand itself, not 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. Manuscripts in this section present advancements in forensic toxicology, and have explored the challenges posed by emerging designer drugs and strategies to combat their proliferation. The pitfalls encountered when the exogenous/endogenous nature of a substance is questioned were presented and discussed. The special issue presents also manuscripts that delve into the ethical implications of drug testing in drug facilitated sexual assaults.
