Yes, RAT (Rapid Antigen Test) tests do expire.
It is crucial to check the expiry date (or use-by date) on the test packaging before using it. According to the provided reference, users are advised to not use a RAT after its expiry date. Using an expired test could lead to inaccurate results, potentially impacting health decisions.
Why Do RAT Tests Expire?
RAT tests contain chemical reagents that can degrade over time. This degradation can affect the test's accuracy and reliability, leading to:
