Hair Follicle Drug Testing - Mahtowa, MN

What it is, How it works

Hair testing is recognized as a robust technique for identifying drug and alcohol consumption. Hair captures a longitudinal record of substances by embedding biomarkers within the fibers of the growing hair shaft. Collected near the scalp, hair can reveal up to a three-month detection span for substances like alcohol. Hair is straightforward to collect, somewhat resistant to tampering, and easy to transport.

A 1.5-inch portion containing approximately 200 hair strands (equivalent to the diameter of a #2 pencil) closest to the scalp produces 100mg of hair, which is the optimal quantity for both screening and verification. For EtG, additional markers, or panels exceeding ten, 150mg is advisable. It's best to weigh the sample using a jeweler’s scale. If scalp hair is not obtainable, an equivalent quantity of body hair is acceptable. In reference to head hair, it pertains exclusively to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The laboratory analysis for a drug test follows four fundamental steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the preliminary handling of a sample within a lab’s framework. This entails ensuring the sample is sealed and conveyed correctly, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry not covered by an electronic chain of custody system.

Screening involves a preliminary assessment for substance misuse. While Screening is a cost-efficient approach to exclude drug usage in most samples, a positive result necessitates confirmation for legal validity. Samples with a presumptive positive in Screening must undergo secondary confirmation.

If a specimen is presumably positive during Screening, additional hair is extracted from the initial sample for Extraction. Here, drugs are isolated from hair at a considerably lower concentration compared to other methods (e.g., urine or oral fluid), establishing hair drug screening as the most challenging technique.

Confirmation of any initial positive outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleansed prior to confirmation as necessary. The comprehensive lab process from Accessioning to Confirmation is evaluated both by the CAP (College of American Pathologists) Hair designation and the certification to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug usage for up to 90 days, unlike urine tests, which feature a shorter window.
• Hard to manipulate: The difficulty in cheating on a hair drug test yields more reliable results.
• Reveals consumption patterns: It can demonstrate a timeline of drug use, not solely recent consumption.

Limitations:

• Unable to detect recent consumption: It takes around 5-7 days for drugs to register in hair.
• Expense: Hair drug tests are typically pricier compared to other testing methods.
• Result variability: Variables such as hair color and individual differences in hair growth can influence the concentrations of drug metabolites.

Note: Despite being known as "hair follicle tests", the analysis is conducted on the hair strand, not the follicle beneath the scalp

Why Hair Follicle Testing Beats Urine Testing

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.
