20mL Negative Liquid Urine Control

20mL Negative Liquid Urine Control - COMBO-H - Detectabuse

The Detectabuse 20mL Negative Liquid Urine Control is a trusted solution for clinical laboratories and toxicology testing facilities that require consistent, accurate quality control. Prepared from stabilized human-based urine, Detectabuse controls are available in both negative and positive formats, with various constituent target levels. This versatile control is designed for in vitro diagnostic (IVD) use under prescription, and plays a critical role in monitoring the precision of drug screening procedures.

Unlike synthetic alternatives, Detectabuse controls use a real human urine matrix, carefully stabilized to extend shelf life and maintain performance integrity. Positive controls are spiked with reference drug standards and/or drug metabolites sourced from ISO-certified manufacturers, all of which are certified to a minimum purity of 98%. These controls are formulated to align with normal physiological parameters, such as pH, specific gravity, and creatinine.

The DEA-exempt status of Detectabuse simplifies handling, storage, and logistics, especially for facilities operating under strict regulatory compliance. This exemption removes the need for additional licensing to purchase or store the product. Furthermore, Their reliability and compliance make them an ideal choice for hospital labs, forensic labs, and diagnostic testing centers.

Human Based, Authentic and Versatile

Detectabuse is available in a range of vial sizes, drug panels, and concentration levels to meet the specific needs of any testing program. Laboratories can choose from standard negative controls, multi-analyte positives, or custom-configured vials tailored to specific testing thresholds. Enhance your lab’s drug screening protocols with the proven performance and regulatory convenience of Detectabuse Liquid Urine Control.

Detectabuse controls offer exceptional stability, helping laboratories reduce waste and manage inventory more effectively. When stored unopened at 2°C to 8°C, the controls remain stable up to the expiration date. After opening, controls maintain their integrity for 31 days refrigerated or six months frozen, and can endure up to five freeze-thaw cycles without affecting performance.

Using Detectabuse Liquid Urine Control is straightforward. Before testing, simply allow the sample to reach room temperature and swirl gently to ensure homogeneity. Transfer an aliquot based on your testing protocol and proceed with analysis. Positive controls will produce positive test results for their listed analytes, while negative controls should yield negative outcomes. These consistent and predictable responses help labs identify errors, verify instrument calibration, and confirm reagent sensitivity.

Features & Benefits:

• Human-Based Matrix: Each bottle contains stabilized human urine, closely mimicking patient samples for realistic testing scenarios.

How to use 20mL Negative Liquid 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. Make sure you follow proper storage and handling procedures. 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
