Hair Follicle Drug Testing - Acalanes Ridge, CA

What it is, How it works

Hair analysis has emerged as a potent method for detecting substance use, capturing long-term substance history by embedding biomarkers within the hair strand fibers. When collected near the scalp, hair can reveal a detection timeline of up to around three months for substances. Collecting hair is straightforward, somewhat tamper-resistant, and easily transportable.

A sample measuring 1.5 inches consisting of approximately 200 hairs (around the diameter of a #2 pencil) nearest to the scalp yields 100mg, which is an optimal sample size for both screening and verification. For EtG, supplemental, and/or tests exceeding 10 panels, a specimen of 150mg is preferred. It is advisable to weigh the sample using a jeweler's scale. Should scalp hair not be available, a comparable volume of body hair is acceptable. References to head hair exclusively concern scalp hair. Other hair types encompass body hair (facial, axillary, etc.).

Process Overview

The laboratory examination of a drug sample involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails initial sample processing within a lab's system, confirming proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing additional data input not available from an electronic chain of custody system.

Screening involves a preliminary evaluation for substances of abuse. While Screening is an economical method to dismiss drug usage in most samples, a positive screen requires confirmation for legal validity. Samples testing presumptive positive in Screening necessitate secondary verification.

If Screening indicates a presumptive positive result, additional hair is extracted from the initial sample for Extraction. During this phase, substances are isolated from hair at a significantly lower concentration relative to alternative methods (ex. urine or oral fluid), which is why hair drug testing is the most intricate technique to implement.

Any positive screening outcome undergoes Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives are cleansed before confirmation as necessary. The laboratory process, from Accessioning to Confirmation, is audited under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.

Benefits of hair drug testing:

• Extensive detection period: Hair drug tests can identify drug usage for up to 90 days, unlike urine tests that have a shorter detection period.
• Hard to manipulate: Achieving deception in a hair drug test is very challenging, thus enhancing result accuracy.
• Chronological data provision: It shows a pattern of substance use over time, not merely recent use.

Drawbacks:

• Inability to detect recent use: Drugs require around 5-7 days to become detectable in hair.
• Expense: Hair drug testing generally incurs higher costs compared to other methods.
• Outcome variations: Aspects like hair color and individual hair growth variability can influence drug metabolite concentration in hair.

Note: Often described as "hair follicle tests", the analysis targets the hair strand itself, not the follicle below the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Acalanes Ridge, CA, hair follicle testing often surpasses traditional urine tests. Superior detection accuracy is a key benefit, as hair tests can identify drug use over a longer timeframe.

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.
