Hair Follicle Drug Testing - Sandy Ridge, NC

What it is, How it works

Hair testing is increasingly recognized as a potent means for detecting drug and alcohol consumption. Hair encapsulates a prolonged history of substance exposure by seizing biomarkers within its fibers as it grows. When sampled near the scalp, hair can reveal substance use spanning up to roughly 3 months for alcohol and drugs. Collecting hair is straightforward, relatively resistant to tampering, and convenient to transport.

A 1.5-inch clip comprising around 200 hair strands (comparable to a #2 pencil’s size) closest to the scalp secures 100mg of hair, the optimal amount for screening and confirmation. For EtG, additional tests, and/or panels exceeding 10 in number, a 150mg specimen is advisable. We suggest measuring the specimen with a jeweler’s scale. If head hair is unobtainable, a similar volume of body hair can be used. In the context of head hair, it specifically pertains to scalp hair alone. Body hair includes all other hair types (facial, axillary, etc.).

Process Overview

The laboratory process for drug test outcomes covers four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning constitutes the primary phase of processing a sample within a lab’s system. This stage ensures the sample was correctly sealed and dispatched, generates a unique LAN (Laboratory Accessioning Number), and completes any outstanding data entry absent an electronic chain of custody system.

Screening entails a preliminary swift inspection for substances of abuse. Although Screening offers a budget-friendly solution to exclude drug consumption in most samples, a positive outcome demands confirmation for legal validity. All samples indicating presumptive positivity in Screening must undergo additional confirmation.

If a sample displays presumptive positivity during Screening, supplementary hair is taken from the original sample for Extraction. Here, drugs are isolated from hair at notably lower concentrations compared to alternative methodologies (e.g., urine or oral fluid), underlining hair drug screening as the most challenging method to execute.

Confirmation of any positive Screening result occurs using GC/MS, GC/MS/MS or LC/MS/MS. Any presumptive positive samples are cleansed before confirmation as necessary. The complete lab process from Accessioning through Confirmation receives scrutiny under both the CAP (College of American Pathologists) Hair classification and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Prolonged detection window: Hair drug tests can identify drug use up to 90 days prior, unlike urine tests with shorter detection spans.
• Challenging to manipulate: It is quite challenging to trick a hair drug test, thereby enhancing result accuracy.
• Yields historical data: Hair tests reveal drug use trends over time, beyond recent usage.

Limitations:

• Incapable of detecting recent usage: Drugs appear in hair after a period of about 5-7 days.
• Expense: Hair drug tests typically cost more than other drug testing forms.
• Variability in results: Hair color and individual growth differences can alter metabolite concentrations within hair.

Note: Commonly termed "hair follicle tests", these assessments analyze the hair strand itself, not the scalp’s underlying follicle.

Why Hair Follicle Testing Beats Urine Testing

Opting for hair follicle testing in Sandy Ridge, NC, offers several advantages over traditional urine tests. Hair tests are renowned for their superior accuracy and reliability. They are less susceptible to tampering and provide a more extended window of detection, offering detailed insights into an individual's drug use history that urine tests simply cannot match.

Extended Detection Window

In Sandy Ridge, NC, hair follicle testing delivers an extensive drug use detection window lasting up to 90 days. This long detection period grants employers a broad perspective on an employee’s substance history, facilitating better-informed decisions based on consistent and comprehensive data. Such an interval provides more holistic insights into substance use behavior over time.

Tamper-Resistant Testing Method

The method of hair follicle testing used in Sandy Ridge, NC, significantly reduces risks of sample tampering. While urine samples can be adulterated with relative ease, hair tests are difficult to manipulate. This greatly enhances the reliability and indefensibility of test results, ensuring trustworthy data for decision-making.

Convenient Nationwide Locations

With convenient testing locations nationwide and locally in Sandy Ridge, NC, Accredited Drug Testing makes the process of accessing testing services straightforward. This network ensures that clients experience rapid and hassle-free services, no matter where they're situated, adding a layer of convenience to the testing experience.

Simple, Confidential Process

The process of obtaining a hair follicle test in Sandy Ridge, NC, is designed to be both simple and confidential. From ordering the test to collecting the sample and receiving the results, users can be assured of privacy and ease throughout the entire process. This simplicity fosters a feeling of comfort and security.

Affordable, Fast Turnaround

In Sandy Ridge, NC, the competitive pricing and rapid turnaround times of hair follicle drug tests offer excellent value. Whether for small enterprises or large corporations, the affordability of these services, combined with their prompt results, provides businesses with a cost-effective means to uphold their workplace standards.

Fast, Accurate, and Reliable Results

The hair follicle drug test in Sandy Ridge, NC, offers fast and reliable outcomes. The precision of this test ensures that substance use is detected with high accuracy, minimizing chances of error or false results. Compared to other testing methods, it provides a dependable and swift evaluation, making it a trusted option for many users looking for accurate diagnostics.

Compliance and Peace of Mind for Employers

Using hair follicle tests in Sandy Ridge, NC, ensures compliance with stringent drug-free workplace policies. This reduces legal risks and enhances overall workplace safety.
