Hair Follicle Drug Testing - North Oaks, MN

What it is, How it works

Hair examinations have gained recognition as an effective method for uncovering drug and alcohol consumption. Hair offers a prolonged account of alcohol alongside other substances by encapsulating biomarkers within the strands of the developing hair. When acquired near the scalp, hair can yield a detection timeframe of up to approximately 3 months for alcohol and drugs. Collection of hair is straightforward, relatively difficult to tamper with, and simple to transport.

A sample measuring 1.5 inches, consisting of around 200 hair strands (resembling the size of a #2 pencil), nearest to the scalp will provide 100mg of hair, the perfect sample size for screening and verification. For tests like EtG, additional elements, and/or analyses exceeding 10 panels, a specimen quantity of 150mg is advised. Using a jeweler’s scale for weighing the specimen is suggested. If scalp hair cannot be obtained, a comparable amount of body hair is collectable. When discussing head hair, it specifically refers to scalp hair. Body hair encompasses all alternative hair types (like facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result involves four principal steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning represents the preliminary step of incorporating a sample into a laboratory’s system. This step checks that the sample was properly sealed and sent, assigns a unique LAN (Laboratory Accessioning Number), and finalizes any leftover data entry not provided by an electronic chain of custody system.

Screening provides an initial rapid assessment for illicit substances. While it is a cost-efficient method to eliminate drug usage in the bulk of samples, a positive screen necessitates confirmation to become court-admissible. Any presumptively positive samples in Screening necessitate secondary validation.

If indicated as presumptively positive during Screening, additional hair is extracted from the original specimen and readied for Extraction. Drugs are isolated from hair at a significantly lower concentration compared to other methods (e.g., urine or oral fluid), which contributes to hair drug screening being the most complex method to execute.

Any affirmative screen result undergoes Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptive positive samples undergo washing before confirmation as required. Every stage from Accessioning through to Confirmation is evaluated under the CAP (College of American Pathologists) Hair designation, maintaining ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests discern drug use up to 90 days, in contrast with urine tests which cover a shorter detection timeframe.
• Challenging to manipulate: Hair drug tests are notably hard to compromise, enhancing result accuracy.
• Supplies historical insight: It indicates drug consumption patterns over a duration, not just recent intake.

Limitations:

• Incapable of identifying recent intake: Drugs require roughly 5-7 days to be identifiable within hair.
• Expense: Hair drug assessments tend to be pricier than alternate testing approaches.
• Result variability: Influences like hair color and individual hair growth peculiarities can alter drug metabolite concentration within hair.

Note: Commonly termed "hair follicle tests", the procedure itself evaluates the hair strand, abstaining from 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.
