10mL Positive Urine Control - 2X Cutoff Low OPI - One Screen
The One Screen 10mL Positive Urine Control is a synthetic urine solution meticulously formulated to simulate human urine, ensuring the accuracy and reliability of urine drug testing procedures. Designed for use with all handheld onsite drug screening devices, this control solution provides a consistent negative result, serving as a critical component in quality control protocols.
One of the standout features of this product is its impressive stability. Unopened, it remains stable for up to 24 months when refrigerated (35–46°F) and up to 12 months at room temperature (77°F). After opening, the control solution maintains its integrity for six months if frozen or until the expiration date, whichever comes first. This extended shelf life ensures that laboratories and testing facilities can rely on the product over time without frequent replacements.
The synthetic urine-based matrix of the One Screen control closely mimics the chemical composition of human urine, including pH, specific gravity, and other key parameters. This similarity ensures compatibility with various testing systems and enhances the accuracy of test results. Moreover, the inclusion of 16 drug constituents within a single control vial, allows for comprehensive testing across multiple substances, streamlining the quality control process.
Ease of Use, Stability and Synthetic
Ease of use is another significant benefit. The product comes in ready-to-use 10 mL bottles, eliminating the need for preparation and reducing the potential for user error. This convenience is particularly valuable in high-throughput environments where efficiency is paramount. Additionally, the control solution is recommended by the majority of handheld device manufacturers, underscoring its reliability and effectiveness in various testing scenarios.
Incorporating the One Screen 10mL Positive Urine Control into your testing protocol not only enhances the reliability of your drug screening processes but also supports adherence to regulatory standards. By providing a consistent negative control, it helps identify potential issues with testing devices, thereby reducing the risk of false positives or negatives and ensuring the validity of test results.
In summary, the One Screen 10mL Positive Urine Control offers a robust solution for quality assurance in urine drug testing. Its synthetic composition, extended stability, comprehensive testing capabilities, and ease of use make it an indispensable tool for laboratories, clinics, and organizations committed to maintaining high standards in drug screening procedures.

How to use 10mL Positive Urine Control
Preparation: Ensure the liquid urine control is stored according to the manufacturer's guidelines, typically at 2–8°C (36–46°F). Do not freeze unless specified. Before use, allow the control to reach room temperature (20–25°C) to ensure accurate results. Gently swirl or invert the bottle several times to ensure homogeneity. Avoid vigorous shaking to prevent foam formation.
Application Methods: There are two common methods for applying liquid urine controls: Use a dropper to apply the control solution directly onto each reagent pad of the test strip. Ensure each pad is thoroughly saturated without over-saturating. Pour the control solution into a clean container. Dip the test strip into the solution, ensuring all reagent pads are immersed. Remove the strip promptly to prevent leaching of reagents.
Reading and Recording Results: Follow the manufacturer's recommended timing for reading results after application. Compare the color changes on the reagent pads to the provided color chart or use an automated analyzer if available. Record the results, including date, time, lot numbers of the control and test strips, and any observations.
Post-Test Handling: After use, promptly recap the control bottle and return it to the recommended storage conditions. Opened controls are typically stable for a specified period, such as 30 days at room temperature or until the expiration date if refrigerated. Avoid touching the dropper tip or pouring spout to any surfaces to prevent contamination.
Troubleshooting: If control results fall outside the expected range, consider the following steps: Verify that the control and test strips are within their expiration dates. Ensure proper storage and handling procedures were followed.
Repeat the test with a new control or test strip.
FAQ – Liquid Urine Control
1. What are Urine Controls?
Urine controls serve as quality control solutions that help verify the accuracy, consistency, and reliability of drug testing and urinalysis systems. They mimic real urine and contain known analyte levels to ensure instruments and reagents function correctly.
2. Why are Urine Controls important?
They help labs to Confirm test accuracy, Detect faulty instruments or reagents, Prevent false positives or negatives and Comply with regulatory standards
3. What types of Urine Controls are available?
Negative Controls contain no drugs or analytes and confirm that systems don’t produce false positives.
Positive Controls include specific drug concentrations to confirm test sensitivity and detection accuracy.
4. What tests use Urine Controls?
Urine controls support: Drug screening (workplace, clinical, forensic), Urinalysis (e.g., kidney, infection, diabetes testing) and Toxicology workflows and laboratory research
5. Are Urine Controls made from real urine?
No, manufacturers synthetically formulate urine controls to replicate human urine properties and deliver consistent analyte concentrations for accurate testing.
6. How do Urine Controls improve lab efficiency?
They reduce retesting, minimize errors, and streamline quality control—helping labs save time and maintain test accuracy.
