Hair Follicle Drug Testing - Oak Park Heights, MN

What it is, How it works

Hair testing is increasingly recognized as an effective means for identifying drug and alcohol consumption. It offers a historical record of substance intake by capturing biomarkers in the strands of advancing hair. When gathered near the scalp, hair can reveal drug and alcohol presence for around three months. Collection is simple, tampering is relatively hard, and transportation is straightforward.

A 1.5-inch segment consisting of roughly 200 hair strands (akin to a #2 pencil) taken nearest to the scalp provides 100mg of hair, the optimal sample size for analysis and validation. For EtG, supplementary, and/or tests exceeding 10 panels, a 150mg specimen is advisable. Utilizing a jeweler’s scale for weighing the specimen is recommended. In case scalp hair is not available, a comparable amount of body hair can be obtained. Head hair refers exclusively to scalp hair, while body hair encompasses other hair types (facial, axillary, etc.).

Process Overview

The essential phases in laboratory processing of a drug test outcome encompass Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial stage where a sample is incorporated into a laboratory’s system. This encompasses ensuring the sample was properly sealed and sent, assigning a unique LAN (Laboratory Accessioning Number), and finalizing data entry omitted by an electronic custody chain system.

Screening executes an initial rapid assessment for drugs. While it offers a cost-effective approach to dismiss drug usage in most samples, confirmatory tests are necessary for legal proceedings. Samples that show preliminary positivity in Screening demand further confirmation.

Should a sample display preliminary positivity during Screening, additional hair is extracted from the original specimen for Extraction. In this stage, drug extraction from hair occurs at much lower concentrations compared to other methods (e.g., urine or oral fluid), rendering hair drug screening the most intricate technique to execute.

For any positive screening result, Confirmation is undertaken via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples receive washing prior to confirmation if required. The comprehensive lab procedure from Accessioning to Confirmation is reviewed adhering to both the CAP (College of American Pathologists) Hair standards and the ISO / IEC 17025 accreditation criteria.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can report drug consumption up to 90 days, unlike urine tests which have a briefer detection period.
• Cheating difficulty: Manipulating a hair drug test is notably challenging, thereby enhancing result precision.
• Offers historical insight: It delivers a consumption pattern over time, not limited to recent usage.

Limitations:

• Lacks recent usage detection: Drugs take roughly 5-7 days to become traceable in hair.
• Expense: Hair drug testing typically incurs higher costs than other methods.
• Result variation: Factors including hair color and individual hair growth differences can influence drug metabolite levels in hair.

Note: Although often termed "hair follicle tests", analysis is performed on the hair strand, 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.
