Hair Follicle Drug Testing - Nashwauk, MN

What it is, How it works

Hair analysis has emerged as an effective method for uncovering drug and alcohol consumption. The hair captures long-term indicators of substances in its fibers during growth. When taken near the scalp, it offers roughly a 90-day detection period for alcohol and drugs. Hair is easy to collect, challenging to tamper with, and straightforward to transport.

A 1.5-inch hair sample of about 200 strands (comparable to a #2 pencil) near the scalp equates to 100mg, which is optimal for testing and verification. For EtG, additional assessments, or tests over 10 panels, 150mg is advisable. We suggest weighing the sample on a jeweler’s scale. If scalp hair is missing, an equivalent amount of body hair may be used. When we speak of head hair, it strictly means scalp hair. Body hair includes all other hair types (such as facial and axillary).

Process Overview

The primary steps in processing a drug test at the lab are Accessioning, Screening, Extraction, and Confirmation.

Accessioning covers the early integration of a sample into the lab’s system. This step ensures the sample is properly sealed and transported, assigns a unique LAN (Laboratory Accessioning Number), and completes any extra data entry absent from an electronic chain of custody system.

Screening provides an initial evaluation for drug presence. While it efficiently screens out non-drug usage in most cases, any positive screen necessitates confirmation for legal acceptance. Samples with presumptive positives in Screening need secondary verification.

For any presumptive positive in Screening, additional hair is prepared for Extraction from the initial sample. Drugs are separated from hair at lower concentrations than other methods (e.g., urine or saliva), which makes hair drug analysis particularly challenging.

After a positive screening, Confirmation is done using GC/MS, GC/MS/MS, or LC/MS/MS methods. All presumptive positives are washed before confirmation if necessary. The lab’s process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair program and ISO/IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair tests can reveal drug use for up to 90 days, unlike urine tests with shorter detection times.
• Hard to falsify: Cheating on a hair test is challenging, ensuring more reliable results.
• Historical insight: It shows drug use patterns over time, not merely recent usage.

Limitations:

• Recent use undetectability: Detecting drugs in hair typically takes 5–7 days.
• Expense: Hair drug screenings are generally costlier than other testing methods.
• Result variability: Aspects like hair hue and individual growth can influence drug metabolite levels in hair.

Note: Commonly known as "hair follicle tests," these tests actually examine the hair strand and 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.
