Hair Follicle Drug Testing - Smith Point, TX

What it is, How it works

Hair analysis emerges as a potent method for detecting drug and alcohol use. It provides an extensive historical record of substances by entrapping biomarkers within the fibers of hair as it grows. When hair is gathered near the roots, it can offer a detection window that spans up to three months for drugs and alcohol. Collecting hair is straightforward, somewhat resistant to tampering, and convenient for transport.

Using a 1.5-inch section consisting of approximately 200 hair strands (comparable to a #2 pencil) closest to the scalp will provide 100mg of hair, the ideal amount for both screening and confirmation. For EtG, add-ons, or tests exceeding 10 panels, it is advised to have a sample weighing 150mg. We suggest using a jeweler’s scale for weighing. Should scalp hair be inaccessible, an equivalent amount of body hair may be gathered. When mentioning head hair, we specifically mean scalp hair. Body hair encompasses all other hair varieties (such as facial or axillary).

Process Overview

The laboratory analysis of a drug test result includes Accessioning, Screening, Extraction, and Confirmation as its four principal stages.

Accessioning refers to the initial integration of a sample into a lab’s system. This stage verifies proper sealing and shipping of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes additional data entry that an electronic chain of custody system might not provide.

Screening represents an initial and quick examination for substances of abuse. Although efficient for excluding drug use in most samples, a positive screening requires confirmation for court admissibility. Samples tentatively positive in Screening necessitate a subsequent confirmation.

If Screening results are presumably positive, further hair is extracted from the original sample and prepped for Extraction. During this stage, substances are extracted from hair at markedly lower concentrations than in other methods (e.g., urine or oral fluids), underscoring the complexity of hair drug screening.

Confirmation for any positive screening is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are washed as required before confirmation. From Accessioning to Confirmation, the full laboratory sequence is evaluated under CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Long detection duration: Hair analysis detects drug use for up to 90 days, whereas urine tests offer a shorter detection window.
• Cheating deterrence: Hair drug tests are challenging to circumvent, thus enhancing result accuracy.
• Retention of usage data: This method shows drug consumption patterns over time, not just recent use.

Limitations:

• Non-detection of recent use: Drugs take roughly 5-7 days to become traceable in hair.
• Expense: Hair drug testing is typically more costly than alternative drug testing techniques.
• Variable results: Hair color and personal hair growth differences might influence drug metabolite concentration within hair.

Note: Despite the common term "hair follicle tests", the test examines the hair strand, not the follicle underneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Smith Point, TX, hair follicle testing outweighs urine tests by offering superior detection capabilities and reliability. It stands out as a preferable choice for drug testing due to its longer detection window and resistance to common cheating methods.

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.
