New Improved Confocal Laser Endomicroscopy System

Celiac.com 11/24/2007 - A new confocal laser microscopic probe has been developed by Mauna Kea Technologies which works in conjunction with conventional endoscopes providing real-time video sequences of the intestinal mucosa magnified 500-1000 times greater than the conventional endoscopic view.  Both normal endoscopic images and confocal images are available simultaneously, allowing the confocal probe to be visually positioned with the endoscope.  This system allows for an immediate diagnosis and eliminates the need to take and prepare intrusive biopsy samples.  The new system is an improvement over previously available confocal laser endomicroscopy systems, being easier and more intuitive to use.  Studies have shown the system to be effective in diagnosing celiac disease.  The Mauna Kea technologies website provides a detailed description of the device.

New clinical studies confirm Mauna Kea Technologies’ endomicroscopy system in a range of procedures

Explaining the term 'confocal' might make this article more meaningful.

Thank you ps, it may be better if the thread title was changed as we now have two 'overwhelmed' topics. If it were 'Bile ducts and celiac?' then it may attract more users with direct experience?

Hello and welcome Maybe? From reading others accounts there's a big variation in how quickly gluten antibodies respond to the gluten diet. I did similar to you and my doctor said that 1 week back on should be enough to show up in a test, but he didn't know what he was talking about sadly... The 2 week figure refers to the endoscopy, for blood testing 8-12 weeks on gluten is more normal. Basically if it comes back positive fine you have your answer. If its negative it may be a false negative due to your going gluten free beforehand. If you want to pursue a diagnosis then yes. Don't go off gluten again until you confirm that all testing is complete. Keep a journal noting any symptoms, that may be useful to you later. More info here: There's some good info in the site faq: https://www.celiac.com/gluten-free/announcement/3-frequently-asked-questions-about-celiac-disease/ I know how you feel! Partway through my gluten challenge I knew that too results notwithstanding. Fwiw I think you've found your answer. Good luck!

Learn more about testing for celiac disease here: http://www.cureceliacdisease.org/screening/ You do have to be on a gluten diet for ANY of the celiac tests (blood and biopsy) to work. While the endoscopy (with biopsies) can reveal villi damage, many other things besides celiac disease can cause villi damage too: http://www.cureceliacdisease.org/faq/what-else-can-cause-damage-to-the-small-intestine-other-than-celiac-disease/ So, both the blood test and endoscopy are usually ordered. There are some exceptions, but those are not common.

Exactly what are your allergy symptoms? Were they IgG or IgE? Allergy testing as a whole is not super accurate -- especially the IgG. Were you on any H1 or H2 antihistamines for the last five days when you were tested? As far as celiac testing, four days without consuming gluten probably would not impact testing.

I've been seeing my dr for a few weeks now about my stomach issues. We've ruled out the gallbladder and h-pylori and today I had the celiac blood tests done. From the reading I've done the past two days, it seems to me that it's highly likely that I have it. I've had digestive issues for years, but they've gotten progressively worse over the past 6 months or so. Pain and nausea when eating, bloat, eternal constipation, dh rash, at it's worse, tight cramp-like pain in a fist under my sternum, radiating through my back and around my right side keeping me up at night. Also heartburn/reflux and trouble swallowing, etc. Anyway, about 2 months ago, I needed a change. I didn't go to the dr immediately because it seemed pointless. (I've mentioned stomach ache when eating to drs before and been blown off.) So, I started the Whole30 elimination diet (takes out soy, grains, dairy, peanuts, and leaves you basically eating meat & veggies). Figured it would show me what I needed to take out of my diet and hopefully feel better. It worked- I felt great! And it seems that grains and gluten are my biggest offenders. But, now I've been off gluten prior to celiac testing. It's been 7 weeks. After 4 weeks I tested steal cut oats, that I later found out were probably glutened. And then nothing until yesterday. Yesterday I had 2 pieces of bread and a muffin and today I had two pieces of bread and then the blood test. Is this going to be enough to show up on the tests? My dr said that it would probably show up, since I had some yesterday and today and was currently having symptoms. But, google seems to say that I should be glutened for 2 wks straight before testing. Has anyone tested positive after just a little gluten? If it's negative should I insist on doing it again after weeks back on gluten? I feel awful, but do want clear answers. Obviously, gluten's not going to be a part of my life any more either way.
