So after reading Hester's post about her CSDA screen with Geneva labs I went back and realized I had done this a couple of years ago. The results showed "NG" for bifidobacterium, though I had 2+ levels for Lacto and 4+ levels for E. Coli.Hester or others, how certain are you as to the results of the Geneva labs test and if we really are "missing" bifidobacterium, is this really a serious problem or not?I gave my results at the time to my gastro here, but she didn't blink an eye at them. She never said - aha, no Bifido. I also had something else called Klebsiella something, which is a borderline organism that may or may not cause diarrhea, etc. But again, my gastro didn't seem to worry about it.Makes me think I should go back to her and press her on it. Hester, how much is the bifidobacterium supplements you take really helping, and how long did it take you?It has now been 2 years since I last took the test - maybe I should do it again. Just don't know.Any views on bacterial balance would be super helpful. Especially the absence of bifido.
