Well, as SactoBob says... you don't really need permission from any doctor or lab to decide you need to stay away from gluten or whatever... but it could be that you are not totally sure that's the problem, maybe, and want some help figuring it out.
Or that you want the diagnosis "validated," so that if you did ever find yourself in need of the hospital, it would be so much more believable if you had an actual diagnosis.
Plus... one point here that SactoBob made that I might disagree with... that hospitals are aware of allergies, etc. Not from what I've heard. I've heard numerous stories of celiacs or parents of celiac children thinking they had it all squared away about their food needs, and then they were given gluten anyway, many of them, especially in the case of the kids, ate it unknowingly and got a reaction at a very bad time.
The best (or worst) horror story I remember reading on a celiac board a couple of years or so ago was a grown man going to have same-day, minor surgery. He told everybody, many times over, about his formally diagnosed celiac condition, and they all assured him they would keep that in mind. So as he recuperated from the surgery, they gave him the usual recuperation foods, cokes and crackers. He felt good, sipped the coke and nibbled the crackers and said to the nurse he had never had such tasty crackers and wanted to know what kind they were so he could buy them and have them at home... and she holds up a package and says something like... "Oh they're just plain old Keebler." Then he became instantly horrified and reminded her for the hundredth time that he wasn't supposed to eat wheat, by doctor's orders. She read the pack and said, "Oh these are okay... they don't have any wheat at all, just enriched white flour." This is both terrifying and amusing... health care professionals do not know the difference between Wheat and enriched white flour.
I wouldn't trsut them, even if I did have a real diagnosis... if I went to stay in the hospital, I'd take my own food... they usually have microwaves and refrigerators on each floor. If you were bad enough off, you could beg a nurse to go microwave your stuff for you.
As to Enterolab... I have no experience, but seen what several people have said. I'm not THAT impressed, although it might be as good or better than the regular tests one would get from a doctor.
The idea behind enterolab makes sense to me... that somebody's poopers would have antibodies to foods ingested causing a reaction, and supposedly it stays that way for up to a year AFTER a person stopped eating those foods. And apparently this is how they test for celiac in some European countries... rumor has it.
But I've seen where some peopel suspect that in this particular test, everyone shows antibodies to wheat... or just about everybody. And the doctor who formulated and does this test... Kenneth Fine, says he believes most people are reactive to gluten, whether they know it or not.
Well I can't argue... I don't know one way or another, but it does seem that Western countries are the gluten-eaters and the ones with the chronic disease, for the most part... but of course we all know there are millions of variables at work, both in concert and in isolation... so who the heck knows? And of course most people don't seem to have chronic diseases associated with wheat, but we see them eat wheat several times a day... so... there's that.
One disturbing thing to me is that Kenneth Fine has said he is about to publish his own studies from Enterolab results soon... he's said this for several years now. It also bugs me that he looks exactly like Jesus Christ on steroids... hmmm... maybe you can't judge a book by its cover... but possible megalomania or something seems to be suggested to me when I see him in action... I could just be paranoid, though... have never corresponded with him or seen him in person... but the net image of him kinda concerns me. He could still be a medical genius and kinda whacked out... so, again... I don't know what to think.
I don't know about insurance either... people complain celiac disease is about as bad as alcoholism for insurance purposes. I have no experience, since I am totally self-diagnosed.
So... I guess all this groundhog rambling is totally unhelpful. DianeR, who used to be on here... did use Enterlab and found it helpful. Not only was she more confident about the gluten giving her troubles, but she said they alerted her to a soy problem she didn't know about... got off soy and found herself feeling better... so... there's a good experience. It's also possible all the people who tested possible for gluten intolerance through Enterolab were in a state of denial about that... which, to me is kinda normal to go through when people first discover they can't have gluten and still be healthy... I know I went through this for five years, finally got smart and got back off the gluten and faced up to the whole situation. Maybe those who complained just really didn't like the idea of being gluten intolerant.
As you can see, I'd make a lousy judge, because I can't ever decide who's right and who's wrong!!! LOL... but those are just my thoughts.
I understand theneed to have a diagnosis... I wish I had one, just so I can tell others or if I ever need to tell health professionals... it would be so much easier to say "My Doctor says," rather than, "From years of misery, denial, research, and trial and error, I've come to realize...."
Good luck with whatever you choose to do
