Our liquid quality control products are known worldwide for their long-term stability and consistency, making laboratories more efficient by eliminating the need for repeat runs.
We offer the most complete line of liquid urinalysis controls, as well as controls for general chemistry, special chemistry, and diabetes.
We apply the most rigorous standards in development and manufacturing, and we’re proud to offer products that give our customers confidence that their tests provide accurate results.
What are clinical laboratory controls and why are they important?
A clinical laboratory control simulates a patient sample and is run on a test system, in the same manner as a patient sample, to estimate test precision and to detect systematic analytical deviations that may arise from reagent or instrument variation.
Clinical laboratory quality control is a measure of precision, or how well a test system reproduces the same result over time and under varying operating conditions.
Controls are usually run at the beginning of each shift, after an instrument is serviced, when reagent lots are changed, after calibration, and whenever patient results seem inappropriate.
A control should be a close simulation of a patient specimen, taking into account properties such as viscosity, turbidity, composition, and color. It should be simple to use, with minimal vial-to-vial variability, because variability could be misinterpreted as systematic error in the method or instrument.
Quantimetrix controls improve the quality of patient care by helping to ensure consistent and accurate test results.
