I would recommend testing Rufus each week for the first year, then twice a month for a year, then monthly and sparatic test for keytones if you can.....you don’t want surprises and it’s a simple test and better to err on the side of caution then be faced with falling 9ut of remission. As you know I tested tons, but Davidson had a tooth issue and here we are again after 4 yrs....he must have missed all of you lol.
