Using an expired Covid-19 test kit can impact its accuracy, potentially leading to false results. This is important to consider, as the reliability of your test result can affect your next steps in seeking medical care or self-isolating.
The expiry date on a test kit indicates the end of its expected shelf life when it performs as intended. It's important to verify this date, mainly because the shelf life can be extended in some cases if new data supports this.
Covid test kits are designed with a specific shelf life, which affects how well they detect the virus. Over time, the test's sensitivity can degrade, meaning it might not detect the virus as well as a newer test.
The chemical agents in Covid test kits are carefully formulated to react with specific viral components. As these agents age, their reactivity may be reduced, affecting the test's ability to identify the virus accurately.
