Samples from incident lot were returned for review and investigation.The samples provided were tested with a 3m lead check test to confirm the dots were manufactured with lead base ink.Upon confirmation of the lead based formulation a sampling of 40 dots were subjected to a simulated point of use study using a standard sterilization cycle of 270ºf for 4-minute cycles and a 20 minute dry time.Completion of testing yielded a 100% success rate in the dots transitioning to their signal color as intended.Dots were then subjected to a 7 day light study in which they were exposed to both artificial and natural light sources for 24 hours over the 7 day period.The results show that the dots exhibited some fading, but no initial color of blue.Based on the testing performed, crosstex was not able to replicate the failure mode.Crosstex is actively committed to providing quality products and client feedback is a tool that is utilized to implement process improvements and corrective actions.Note: a retrospective review of potential serious injury complaints was performed.This mdr was identified as a reportable malfunction as a result and filed as part of the review activities.
