Are These Blood Tests Sufficient To Diagnose Celiac?

I asked this question before and was given an answer.  However, since then, the lab I was going to use reduced the price and am not sure the panel includes the same tests. 

 

 

 

 

Endomysial antibodies IgA
Celiac Disease Complete Panel
Tissue transglutaminase, IgG
Tissue transglutaminase, IgA
Deamidated gliadin IgA!
Deamidated gliadin IgG!
Serum IgA quantitation!

Why do I even have to ask these questions?  There should be a standard.

Looks good to me.  I don't know what a "Celiac Disease Complete Panel" is, but the others are the most recent, most specific, and when you combine them, the most sensitive celiac blood tests out there. Unless you are one of the small minority who serologically test negative (to me it appears to be somewhere between 5-15% of all celiacs), those tests should be accurate for you.

 

Good luck. I hope your last days of eating gluten before you test are tasty and not too uncomfortable.  ;)

That is the best Celiac panel I've ever seen.  

I wished mine was as complete.

And on sale too!

 

Eat 4 slices of bread for at least 12 weeks.

4 slices?  Wow.  Right now I eat one slice of flourless bread every day.  Not sure I could handle 4.

 

If I eat a giant slice of cake the night before the blood test, could that give me a more accurate diagnosis?

The most common suggestion is that 2 slices of bread (or the equivalent in other forms) a day is enough. Flourless bread might not work at all, since the flour is the gluten source.

 

Antibodies build up over time, hence the 12 weeks. A big load the night before won't make much difference.

      Hello, @NCalvo822, Blood tests for Celiac Disease test for antibodies our bodies make in response to gluten exposure. These Tg IgA 2 antibodies mistakenly attack our own bodies, causing problems in organs and tissues other than just the digestive tract. Joints can ache, thyroid problems or the pancreas can develop.

      symptoms.

      @Rebeccaj, When you smell toast or pasta cooking, that means that particles of that food are floating around in the air. Airborne gluten can then be inhaled and swallowed, meaning the food particles get into your digestive tract. If you're careful to avoid gluten and are still having symptoms, those symptoms could be caused by vitamin deficiencies...

      Hello, @NCalvo822, Blood tests for Celiac Disease test for antibodies our bodies make in response to gluten exposure.  These Tg IgA 2 antibodies mistakenly attack our own bodies, causing problems in organs and tissues other than just the digestive tract.  Joints can ache, thyroid problems or the pancreas can develop.  Ataxia is just one of over two hundred symptoms of Celiac Disease. Some people with Celiac Disease also make tTg IgA 6 antibodies in response to gluten exposure.  The tTg IgA 6 antibodies attack the brain, causing ataxia.  These tTg IgA 6 antibodies are also found in people with Parkinson's disease, though they may not have Celiac Disease.  First degree relatives (parents, siblings, children) of those diagnosed with Celiac should be tested as well.  Celiac is genetic.  Your mom and sister should be tested for Celiac, too!   Definitely a good idea to keep to a gluten free diet.

Deficiency symptoms of B vitamins resemble gastrointestinal symptoms when after eating gluten.  Gastrointestinal Beriberi is a form of Thiamine deficiency.   Do talk to your doctors about supplementing with essential nutrients while on the gluten free diet, especially if you're consuming processed foods.
