Well, the fecal blood test result was positive. I suspected that it might be because my son has been cheating on the diet for the last week without my permission - and not in a small way. Not to mention the fact that he hasn't been eating his vegetables that I pack in his lunch - and sometimes with dinner (I found his veggies in the cat's bowl last night after he went to bed). Well, as the saying goes - you give them and inch and they take a mile. It's back to the basic diet and enemas again for him. He's not happy about it, but there's no alternative as far as I'm concerned. I plan to perform the test again in about a month. Will post the results then as well. Thanks again Sheldon, for everything.
