I did 23andME and a lot of research on the internet. Sent SI gene raw data and LiveWello results to a group of doctors and researchers doing starch/sugar/IBS studies with DNA attached. They said it was positive and to follow up with a GI who knows about CSID. It took some detective work to find one, but am now waiting for appointment in a few weeks with the only one in the city. The "Gold Standard" is an upper endoscopy with biopsies and Disaccharidase Enzymes Assay lab test - which I asked for 3 years ago with another GI in the city who refused to do it saying "I don't treat those diseases" --I wanted him to verify the IBS/ Lactose Intolerance/Hereditary Fructose Intolerance they seem to think I had...but the diet just wasn't working like it should. I've suffered with this all my life and never thought the doctors had their diagnosis right. WOW! It just CLICKED when a friend's daughter was diagnosed with CSID and I looked it up on the internet. I am doing the first 2 weeks of the CSID Induction Diet and can really tell a difference. I ... More

Hello, I am currently searching for the SI gene template or report and I m unable to find one. Can you be of assistance helping me locate it? Also, what lab performed your DNA tesyting for CSID and what was the cost?
thanks

Had a confirmed DNA test positive for Congenital Sucrase-Isomaltase Deficiency , so now awaiting an appointment with a GI who is supposed to be familiar with this rare carbohydrate digestive disorder. The gold standard diagnosis is an upper endoscopy with biopsies so that we can figure out which of the 5 kinds it is [but I can eliminate 2 of them from my personal history with foods]. In the meantime, I am using the first 2 week of the Induction Diet which is safe to use without enzyme replacement [only available by prescription, and not a cure-all anyway]. Having to relearn how to eat has been an adventure.... but, I am also feeling better too.

I deal with a lot of allergies.

I would find a Naturopathic or integrative MD doctor who uses genetic testing and interpretation.

An allergist might help as well. Not sure where you live but. Allergy Associates of Lacrosse is really good!
