Hair Follicle Drug Testing - Sonora, TX

What it is, How it works

Hair analysis is recognized as a potent means for detecting substance use. The strands encapsulate a long-term history of alcohol and drug intake by storing biomarkers within the fibers of the hair as it develops. When taken near the scalp, a hair sample can reveal drug and alcohol use for up to roughly three months. It's straightforward to obtain, relatively tamper-resistant, and convenient to transport.

A sample of 1.5 inches of approximately 200 hairs (around the thickness of a #2 pencil) near the scalp yields 100mg, which is perfect for both screening and verification. For EtG, additional tests, or those exceeding 10 panels, 150mg of the sample is advisable. We suggest using a jeweler’s scale to measure the sample's weight. In the absence of scalp hair, a similar amount of body hair may be harvested. When discussing head hair, we specifically mean scalp hair. Body hair encompasses all other types (such as facial, axillary, etc.).

Process Overview

There are four primary phases in processing a lab drug test result: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the first step of incorporating a sample into the lab’s database. This step involves confirming the sample’s proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data input absent from an electronic chain of custody system.

Screening performs an initial swift evaluation of substance misuse. Although Screening is a budget-friendly method to exclude drug use in most samples, a court-admissible positive screen needs confirmation. Samples that appear positive in Screening necessitate an additional confirmation.

If Screening indicates a presumptive positive, additional hair is extracted from the original sample and readied for Extraction. In this procedure, drugs are retrieved from hair at significantly lower concentrations than most other methods (e.g., urine or oral fluid), rendering hair drug testing the most challenging method to execute.

Any positively screened samples undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. All samples deemed presumptively positive are cleansed prior to confirmation as required. The entire process from Accessioning to Confirmation is evaluated according to the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can detect substance usage for as long as 90 days, whereas urine tests have a more limited detection timeframe.
• Cheating is challenging: Hair drug tests are notably hard to manipulate, increasing the accuracy of the results.
• Offers historical insights: It reveals a pattern of drug consumption over time instead of merely recent usage.

Limitations:

• Not apt for recent use: Detection in hair takes around 5-7 days post-use.
• Expense: Hair drug tests are usually pricier than other testing techniques.
• Inconsistent results: Variables like hair color and individual hair growth differences can influence the concentration of drug metabolites in hair.

Note: Although often termed "hair follicle tests," the analysis targets the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing outperforms traditional urine tests in Sonora, TX, due to its superior detection accuracy and reliability. Unlike urine tests, hair analysis can identify substance use over a longer period, offering a broad view of an individual’s drug history.

While urine tests may capture recent use, hair testing gives a clear, comprehensive picture, making it a preferred method for thorough substance use assessment across various sectors, enhancing safety and compliance.

Extended Detection Window

Hair follicle testing in Sonora, TX provides an extended detection window, capturing substance use history up to 90 days prior. This expansive timeframe offers employers a thorough understanding of an applicant or employee's drug usage habits.

Compared to other testing methods, this longer window gives a complete snapshot of consistent behaviors over time. Employers can make informed decisions based on comprehensive data, enhancing workplace safety and integrity.

Tamper-Resistant Testing Method

In Sonora, the reliability of hair follicle tests lies in their tamper-resistant nature. These tests significantly reduce the chance of sample manipulation, ensuring the authenticity of results and maintaining trust in substance use assessments.

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.
