Guest guest Posted April 27, 2012 Report Share Posted April 27, 2012 Morning Everyone. The last time I had a CD-57 test was in 2007 and it was at 42. I have been doing the GB-4000 since 1/30/12, (just the hand held contacts, not the plasma bulb unfortunatley) I had the CD-57 test again and it came back at 82. How often should I keep checking ???? Next month ???? Six weeks ???? eight weeks ???? Thanks. J Quote Link to comment Share on other sites More sharing options...
