Hair Follicle Drug Testing - Lengby, MN

What it is, How it works

Hair testing is recognized as a potent method for identifying drug and alcohol use. The hair strand retains biomarkers in its fibers, providing a lasting record of substances consumed. When sourced near the scalp, hair can reveal substance use over an estimated duration of up to three months. The collection of hair is straightforward, challenging to tamper with, and convenient to transport.

A sample measuring 1.5 inches, consisting of approximately 200 hair strands (comparable to the thickness of a #2 pencil) near the scalp, yields 100mg, which is ideal for both screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, a 150mg sample is advisable. For accuracy, weighing this sample on a jeweler's scale is recommended. In the absence of scalp hair, an equivalent quantity of body hair can be used. When discussing head hair, we specifically mean scalp hair. The term body hair encompasses all other hair types (such as facial or axillary).

Process Overview

The core stages in laboratory drug test processing include Accessioning, Screening, Extraction, and Confirmation.

Accessioning begins with processing a sample into the laboratory's database. This involves verifying proper sealing and shipment of the sample, generating a random LAN (Laboratory Accessioning Number), and completing any necessary data entry absent from an electronic chain of custody.

Screening is an initial expedited assessment for drug presence. Although an effective way to negate drug usage on most samples cost-efficiently, a positive indication must be verified for court validity. Any sample showing a presumptive positive in Screening undergoes further confirmation.

If Screening suggests a positive result, additional hair is sourced from the initial sample and readied for Extraction. This step extracts drugs from the hair at much lower concentrations compared to other methods (e.g., urine or oral fluid), which renders hair drug screening particularly challenging.

Confirmation of any positive screening result employs GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples are washed before confirmation if necessary. The laboratory process from Accessioning through Confirmation is subject to evaluation under the CAP (College of American Pathologists) Hair accreditation and ISO / IEC 17025 standards compliance.

Advantages of hair drug testing:

• Extended detection period: Hair tests identify drug use extending up to 90 days, unlike urine tests with shorter detection spans.
• Hard to falsify: The challenge of tampering with a hair drug test ensures more reliable outcomes.
• Historical substance use data: It outlines a substance use trend over time, not just recent intake.

Limitations:

• Incapable of recent use detection: Detectability in hair occurs roughly 5-7 days post-consumption.
• Expense: Hair drug testing is typically pricier than alternative testing methods.
• Result variability: Elements like hair color and individual hair growth patterns can influence the level of drug metabolites in hair.

Note: Commonly termed as "hair follicle tests," the examination actually concerns 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.
