Hair Follicle Drug Testing - Campbellton, TX

What it is, How it works

Hair analysis has emerged as a substantial method for identifying substance and alcohol consumption. Hair encases enduring evidence of alcohol and other substances by capturing biomarkers within the strands as they grow. When obtained closely to the scalp, it offers a detection span for alcohol and drugs extending to roughly three months. The collection of hair is straightforward, tough to tamper with, and simple to send.

A sample measuring 1.5 inches comprising around 200 hair strands (similar in size to a #2 pencil) near the scalp equates to 100mg of hair, deemed the optimal sample for both analysis and validation. For EtG, supplementary analysis, and/or extensive panels above 10, a specimen of 150mg is advised. Using a jeweler’s scale is suggested for weighing. In the event of limited scalp hair, a similar quantity of body hair can be gathered. The term head hair refers only to scalp hair. Body hair encompasses all other hair categories (facial, axillary, etc.).

Procedure Outline

Four primary phases comprise the lab processing of a drug test outcome: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial integration of a specimen into a lab’s infrastructure. It encompasses confirmation of the specimen’s sealed and correct shipment, allocating a unique LAN (Laboratory Accessioning Number), and completing any further data entries absent from an electronic chain of custody mechanism.

The Screening process involves an initial, swift evaluation for substance misuse. While Screening economically discerns drug intake in most samples, a positive result must undergo confirmation to hold legal validity. Any samples with a positive indication in Screening necessitate additional confirmation.

In instances where a sample indicates positivity during the Screening phase, additional hair is extracted from the primary specimen for Extraction. This phase extracts drugs from hair at significantly lower concentrations compared to alternative methodologies (e.g., urine or oral fluid), establishing hair drug screening as the most challenging method to execute.

Confirmation of all positive screening outcomes occurs through GC/MS, GC/MS/MS, or LC/MS/MS. Prior to Confirmation, all samples indicating presumptive positivity are washed when necessary. The full laboratory process from Accessioning through Confirmation is subject to review under the CAP (College of American Pathologists) Hair designation alongside ISO / IEC 17025 standards accreditation.

Benefits of hair drug assessment:

• Extended detection span: Hair drug assessments can reveal drug intake up to 90 days back, while urine tests possess shorter detection spans.
• Cheating difficulty: Hair drug assessments are notably difficult to manipulate, enhancing result precision.
• Supplies historical insight: It offers a narrative of drug intake across a timeline, not solely recent use.

Constraints:

• Lacks recent use detection: A timeframe of approximately 5-7 days is required for drug presence to manifest in hair.
• Expense: Generally, hair drug assessments incur higher costs compared to other methods.
• Result variance: Variables such as hair color and personal hair growth differences can influence metabolite concentration in hair.

Note: Although commonly called "hair follicle tests", the examination targets the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

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.
