What does a change in the indicator tape on a sterilization bottle indicate?

A change in the indicator tape on a sterilization bottle signifies that the bottle has been through a sterilization cycle. This tape typically contains indicators that change color or appearance when exposed to the specific conditions of sterilization, such as temperature and pressure. The purpose of the indicator is to provide a visual confirmation that the item has been subjected to the necessary sterilization process, ensuring that it is safe for use in a clinical setting.

In addition to confirming exposure to sterilization conditions, it does not necessarily indicate if the cycle was successful or if the sterile condition has been maintained after the process. Therefore, while it confirms the completion of a sterilization cycle, further verification may be needed to assess the overall sterility and usability of the items.
