This information is nothing new, but this recent study is worth reading for anyone looking for information about metal ion readings.

Thanks John. You're right, it reinforces previous status, but some times repetition gives us more confidence.
We're all looking at statistics, the chance that the implant can fail. The fact that we can rely on blood levels as one way to identify failure and it is reliable gives me a good feeling.
Since I have low blood levels, it calms my mind. I also value that if my levels go up, I can catch a problem early, minimize the damage even if I need a revision.
