How Accurate Is The Ttg Blood Test?


amicamom

Recommended Posts

Celiac Disease Comprehensive Panel tests are back...I AM FLABBERGASTED TO SAY THE LEAST...Charity, Bethany and I all tested NEGATIVE for Celiac Disease.

Bethany - TTG Antibody IGA <3 (negative is anything <5)

Bethany - Gliadin Antibody (IGA <3 (negative is anything <11)

Charity - TTG Angibody IGA <3 (negative is anything <5)

Charity - Gliadin Antibody <3 (negative is anything <11)

The lab did not perform the rest of the panel based on this information.

Me - TTG Antibody, IGA <3

Me - Gliadin Antibody (IGA) 8

IGA, Serum 212

The lab did not perform the rest of the panel based on this information.

I don't know what to think now. Of course, I am thankful we do not have celiac disease. However, I was certain this was the answer to my babies problems. What do I do now? Bethany is obviously thriving on a gluten free diet so I know there must be some kind of sensitivity. She is still scheduled to see a GI doctor next week.

The above tests did not even show a SENSITIVITY to gluten, right?

What should I do now?

The tTG test is pretty accurate.

Were you all on gluten before testing? If you were gluten free then that can really screw up tests.

False positives can occur - a gluten free diet can cause a false positive, and individuals deficient in IGA antibodies and cause a false positive.

All of the celiac tests can be inaccurate in children under 2 years. Also, there is some question about accuracy under 5 years of age. If your child is thriving on a gluten free diet, I would leave her on it for now. Or you could put her back on gluten and pursue an endoscopy and biopsy. Just be sure to get someone who knows how to do the biopsy properly - 4-6 samples from the 3rd portion of the duodenum. There are cases where intestinal damage is apparent, even when blood work is negative.

      Take it easy! I was just prompting you for some clarification.  In the distillation process, the liquid is boiled and the vapor descends up a tube and condenses into another container as it cools. What people are saying is that the gluten molecules are too large and heavy to travel up with the vapor and so get left behind in the original liquid solution. Therefore, the condensate should be free of gluten, no matter if there was gluten in the original solution. The explanation contained in the second sentence I quoted from your post would not seem to square with the physics of the distillation process. Unless, that is, I misunderstood what you were trying to explain.

      No they do not contradict each other. Just like frying oil can be cross contaminated even though the oil doesn't contain the luten protein. The same is the same for a distilled vinegar or spirit which originally came from a gluten source. Just because you don't understand, doesn't mean you can tell me that my sentences contradict each other. Do you have a PhD in biochemistry or friends that do and access to a lab?  If not, saying you don't understand is one thing anything else can be dangerous to others.

      The reason that it triggers your dermatitis herpetiformis but not your celiac disease is because you aren't completely intolerant to gluten. The celiac and dermatitis herpetiformis genes are both on the same chronometer. Dermatitis herpetoformus reacts to gluten even if there's a small amount of cross contamination while celiac gene may be able to tolerate a some gluten or cross contamination. It just depends on the sensitivity of the gene.

      @Mynx, you say, "The reason this is believed is because the gluten protein molecule is too big to pass through the distillation process. Unfortunately, the liquid ie vinegar is cross contaminated because the gluten protein had been in the liquid prior to distillation process." I guess I misunderstand what you are trying to say but the statements in those two sentences seem to contradict one another.

      It isn't a conjecture. I have gotten glitened from having some distilled white vinegar as a test. When I talked to some of my scientists friends, they confirmed that for a mall percentage of people, distilled white vinegar is a problem. The cross contamination isn't from wheat glue in a cask. While yhe gluten protein is too large to pass through the distillation process, after the distillation process, the vinegar is still cross contaminated. Please don't dismiss or disregard the small group of people who are 100^ gluten intolerant by saying things are conjecture. Just because you haven't done thr research or aren't as sensitive to gluten doesn't mean that everyone is like you.
