Evaluation: note that the lot number reported was 611146-01 however, that is not a valid lot number.As such the investigation was performed without lot number.Without a valid lot number we were unable to review a manufacturing batch record or evaluate product retains.We did however receive returned product and were able to investigate based on that.Returned product was received on 04/19/2021.Of the returned product received, 12 samples were processed.All of the samples transitioned.Note than one lock fell off during testing so the transition was slightly lighter than the remainder of the locks but it did still turn noticeably from the initial blue color.As the testing of the returned product did not yield any issues with the product transitioning, the most likely root cause is end user storage conditions or end user equipment.It is important that steam indicator cis are stored correctly to ensure the product performs as expected.The product should be stored at 20 - 25°c average, with a relative humidity range of 30 - 70%.Avoid exposure to direct sunlight and/or heat sources.Store away from sterilants.Labeling is provided to guide the end user to avoid exposure to natural or uv lights, extreme heat sources, and residual sterilants.
