Hair Follicle Drug Testing - Annetta North, TX

What it is, How it works

Hair testing is increasingly recognized as an effective method for detecting drug and alcohol use. It offers a long-term overview by preserving biomarkers within the hair's fibers as they grow. When collected near the scalp, hair samples can provide an up to 3-month detection period for alcohol and other drugs. Collecting hair is straightforward, relatively resistant to tampering, and convenient for shipping.

A 1.5-inch hair sample containing around 200 strands (roughly the thickness of a #2 pencil) from the scalp yields approximately 100mg, which is ideal for initial screening and confirmation. When performing EtG, add-ons, or extensive tests above 10 panels, 150mg is advised. Using a jeweler’s scale for weighing the specimen is recommended. If scalp hair isn't available, a similar amount of body hair can be used. By head hair, we mean scalp hair exclusively, while body hair encompasses all other types (such as facial and axillary hair).

Process Overview

The drug test processing in a lab comprises four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is about integrating a sample into a lab’s system initially. This step includes confirming the proper sealing and shipping of the sample, issuing a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry outside an electronic chain of custody system.

Screening provides a preliminary assessment for substance abuse. Although Screening is cost-efficient to eliminate drug use across most samples, any positive screening result must be confirmed for it to be accepted legally. Samples that yield a presumptive positive in Screening necessitate further confirmation.

If a sample is deemed presumptive positive during Screening, additional hair is drawn from the initial collection for Extraction. Here, drugs are extracted from hair in concentrations lower than other methods like urine or oral fluids, making hair drug screening particularly challenging.

Confirmation of any positive findings is accomplished via GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with presumptive positives undergo washing pre-confirmation as required. The entire lab process from Accessioning to Confirmation is subjected to reviews under the CAP (College of American Pathologists) Hair criteria and aligns with ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for a duration of up to 90 days, unlike urine tests which have a more limited detection span.
• Hard to tamper: The difficulty in altering a hair drug test assures more accurate outcomes.
• Presents historical patterns: It provides an overview of drug use over time, not just recent activity.

Limitations:

• Doesn't detect recent consumption: Hair needs roughly 5-7 days before drugs become detectable.
• Expense: Hair drug tests typically cost more than alternative testing methods.
• Result variations: Factors like hair type and individual growth rates may influence drug metabolite concentrations in hair.

Note: Despite often being called "hair follicle tests", the analysis targets the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why Hair Follicle Testing Beats Urine Testing in Annetta North, TX, lies in its superior detection methods. Hair testing offers a much longer detection window than urine testing, spanning up to 90 days compared to just a few days with urine. This extended period provides a more comprehensive view of someone's substance use history, which can be crucial for workplace assessments.
Hair tests are nearly impossible to falsify, enhancing trust in the authenticity of the results.

Extended Detection Window

Extended Detection Window is a major benefit of hair follicle testing in Annetta North, TX. While urine tests typically detect drug use within a few days, hair exams extend this window to up to 90 days. This gives employers a more thorough understanding of an employee's or candidate's potential drug use, allowing for more informed decision-making regarding hires or promotions.

Tamper-Resistant Testing Method

One of the key advantages of hair follicle testing in Annetta North, TX, is its tamper-resistant nature. Unlike urine tests, where samples are easy to adulterate, hair tests significantly reduce this risk, delivering reliable results that stand up in legal and professional contexts.

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.
