Hair Follicle Drug Testing - Bejou, MN

What it is, How it works

Hair analysis is recognized as an effective method for identifying drug and alcohol consumption. Hair strands capture biomarkers from alcohol and drugs, providing a historical overview of substance intake. Samples collected near the scalp can reveal drug and alcohol use for up to three months. Hair samples are straightforward to gather, moderately resistant to tampering, and simple to transport.

A 1.5-inch section consisting of approximately 200 hair strands (comparable to the thickness of a #2 pencil) obtained close to the scalp will yield about 100mg of hair, suitable for testing. For EtG and additional panels exceeding 10, a sample size of 150mg is advisable. It is suggested to measure the sample using a jeweler’s scale. If scalp hair isn’t available, a comparable amount of body hair may be used as a substitute. “Head hair” refers exclusively to scalp hair, while “body hair” encompasses all other types (facial, underarm, etc.).

Process Overview

The laboratory testing process consists of four primary steps: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample is logged into the lab’s system, where its sealed condition is checked, a LAN (Laboratory Accessioning Number) is assigned, and necessary data not covered by an electronic chain of custody is entered.

Screening comprises a rapid assessment to detect drugs of abuse. Although Screening is economical for excluding drug use in many samples, a positive result requires official confirmation for legality. Samples testing positive during Screening need an additional verification step.

Samples that test positive in Screening proceed to the Extraction stage, where additional hair from the initial sample is processed. Drugs are extracted at much lower concentrations than other methods (e.g., urine or oral fluid), which is why hair analysis poses greater challenges.

Positive results are cross-verified using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Before confirmation, samples undergo washing if necessary. The overall laboratory process, from Accessioning to Confirmation, undergoes examination for compliance with the CAP (College of American Pathologists) Hair standards and ISO/IEC 17025 certification.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can uncover substance use for up to 90 days, unlike urine tests with shorter detection spans.
• High resistance to manipulation: Cheating a hair drug test is extremely challenging, enhancing result reliability.
• Tracks long-term patterns: It illustrates a timeline of drug consumption, rather than recent activity alone.

Limitations:

• Does not show immediate use: Drugs become traceable in hair after approximately 5-7 days.
• Cost factor: Hair tests typically incur greater expenses than alternative testing methods.
• Result disparities: Variables such as hair color and personal growth differences can influence metabolite levels in hair.

Note: Although often termed as "hair follicle tests," the evaluation is conducted 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.
