Why do test strips expire?

Test strips, including those used for urine analysis, have expiration dates due to their chemical and physical components. Over time, the chemicals on the strip that react with urine can degrade or become less effective. This degradation can affect the accuracy of the test results, as the chemical reactions may not occur as intended or may produce unreliable readings.

The expiration date is set based on stability studies conducted by the manufacturer, which determine how long the test strips maintain their intended performance under specified storage conditions. Factors such as exposure to moisture, heat, or light can accelerate the degradation process, potentially compromising the accuracy of the test.

Diagnox test strips are designed with high-quality standards to ensure reliable performance up to their expiration date. The longevity and accuracy of Diagnox test strips are backed by rigorous testing and stability evaluations. As long as they are stored correctly, in a cool, dry place, and the packaging is intact, Diagnox test strips provide reliable results throughout their shelf life.

To ensure accurate testing, always check the expiration date before use and follow storage instructions carefully. Using test strips past their expiration date may lead to inaccurate results, so replacing expired strips with new ones is essential for maintaining effective monitoring of health parameters.
