Hair Follicle Drug Testing - Meadows Place, TX

What it is, How it works

Hair testing is widely recognized as an effective means for identifying drug and alcohol consumption. By capturing biomarkers within the fibers of growing hair strands, it offers a long-term record of alcohol and drug use. When collected near the scalp, hair can reveal up to a three-month history of alcohol and drug use. Hair is straightforward to gather, fairly tough to manipulate, and simple to transport.

A 1.5-inch section of roughly 200 hair strands (comparable to a #2 pencil's thickness) near the scalp yields 100mg of hair, the optimal amount for analysis and validation. For EtG, add-ons, or tests exceeding 10 panels, 150mg of the sample is advised. We suggest measuring the sample on a jeweler’s scale. If scalp hair isn't available, an equivalent amount of body hair can be used. When mentioning head hair, we mean scalp hair only. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The four primary stages in the lab processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial integration of a sample into a lab's system. This step includes ensuring the sample was correctly sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and completing any extra data input not available via an electronic chain of custody system.

Screening entails an initial fast examination for substance abuse. While Screening offers a budget-friendly method to exclude drug use on most samples, a positive screen requires confirmation to be valid in legal settings. Any samples that show a presumptive positive in Screening must undergo a secondary confirmation.

If a sample is presumptively positive during the Screening phase, more hair is taken from the original sample and prepared for Extraction. In this phase, substances are removed from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening the most challenging methodology to execute.

Confirmation of any positive screening result is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleaned before confirmation as needed. The entire process from Accessioning to Confirmation is evaluated under both CAP (College of American Pathologists) Hair designation and accreditation per ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which have a shorter detection window.
• Difficulty to cheat: It is significantly hard to tamper with a hair drug test, enhancing the accuracy of the results.
• Provides historical data: It can reveal a pattern of drug use over an extended period, not just recent usage.

Limitations:

• Cannot detect recent use: It takes about 5-7 days for drugs to become detectable in hair.
• Cost: Hair drug tests are usually more costly than other drug testing approaches.
• Variations in results: Factors like hair color and personal differences in hair growth can influence drug metabolite concentrations in hair.

Note: Although often referred to as "hair follicle tests," the test actually analyzes the hair strand and not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why Hair Follicle Tests Outperform Urine Tests in Meadows Place, TX

Hair testing surpasses urine tests with a superior detection accuracy. Unlike urine tests, hair tests provide a longer window for substance detection, increasing reliability. Hair follicle tests are less susceptible to tampering, offering a much stronger defense against attempts to obscure true drug or alcohol use history.

Extended Detection Window

Extended Detection Period in Meadows Place, TX

Hair follicle testing affords a significant advantage over other testing methods, offering up to a 90-day detection window. This extended period provides employers with a full substance usage profile of employees or prospective hires, unlike the limited timeframe that urine tests cover.

Such comprehensive detection allows companies to make informed decisions founded on thorough knowledge of an individual's long-term substance use.

Tamper-Resistant Testing Method

Secure Testing Method in Meadows Place, TX

The hair follicle testing process ensures a level of tamper-resistance unmatched by traditional 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.
