Blood Test Interpretation

4 posts in this topic

Hello all! I am new to this site and have an endoscopy and biopsy scheduled in two weeks. Unfortunately, my doctor did not explain my blood results to me and I don't have another appointment with him to go over it. He simply said some results were positive and the biopsy is the next step. (He is a Celiac Specialist so although I'm upset he didn't explain more, I'm hoping he is still a capable doctor).

I have a biology degree and an understanding of the basics..but if anyone can give me some insight, I would be grateful. Especially the TTG results. I am soooo stressed about the biopsy, mostly the sedation.

Here are my results:

-IGA serum: 191 (normal)

-IGA AB group: 191 (normal)

-endomysial IGA anibody: POSITIVE titer (high)

-Gliadin (Demidated) AB, IGA: 152.5 (high)

-Gliadin (Demidated) AB, IGG: <20 (normal)

-Transglutaminase IGA : 47 (high)

-Transglutaminase IGG: 8 (high)

I'm so glad I found this website. I don't have much support for this and am glad I can find this support! :) :)

Just going by your blood work it seems like you have celiac. The EMA and Deamidated gliadin are specfic to celiac. The tTG can be elevated in other autoimmune diseases also, but since the others are positive it's safe to say the elevated tTG is from celiac also. Some doctors will diagnose on blood work alone.

The EGD isn't that bad. You won't remember a thing. Just make sure the doctor takes enough samples to check for celiac. I think it is recommended to have 8-10 taken from different areas in the small bowel. They will also look at other things besides celiac. They look at the esophagus and will take biopsies if necessary and examine the stomach. It's pretty routine to have a biopsy in the stomach to look for H Pylori. Even if the biopsy comes back negative doesn't mean you don't have celiac. You can get a false negative biopsy due to an inexperienced doctor performing the biopsy, inexperienced pathologist looking at the samples, not enough samples taken, samples not taken in damaged areas(damage can't be seen with the naked eye and it can be patchy with normal areas and damaged areas) or damage is in another area of the small bowel that is beyond the reach of the scope. The scope only goes into the first portion of the duodenum(small bowel) and it's not very far.

After your scope I would go gluten free. No need to wait on the biopsy results. With blood work like yours I wouldn't hesitate to go gluten free and call it celiac and I'm not a doctor.

I put my youngest son gluten free without a scope/biopsy based on a postive IgA tTG alone. He does not have any other autoimmune diseases so it was safe to say it was because of celiac and the fact that I'm blood and biopsy diagnosed. My oldest son hasn't had any positive blood work in the past 4 years and even had a negative biopsy. He went gluten free almost a year ago and has done wonderful. I had toyed with the idea for two years to put him gluten free also but was hard to commit without anything positive. Now if he gets CC'd he is miserable. So he can't be diagnosed celiac, but he is definately gluten intolerent.

Ditto what Roda said. Lots of positive antibody tests, especially the anti-EMA, scream celiac.

The Biopsy is easy!

go to sleep for 10 min then feel great after. :-)

its only sedation, not anaesthetic

good luck.

    • Working a modifying a recipe to be both Vegan and Grain free. I am a bit low on funds right now and can not test it. Feed back is welcome and if you do it perhaps  get me a grams breakdown for duplication. 1 cup almond flour
      ½ cup unsweetened shredded coconut
      1 teaspoons cinnamon
      1 teaspoons apple pie spice
      1 teaspoon baking soda
      ½ teaspoon salt
      ¾ cup unsweetened applesauce
      ½ cup almond butter
      ½ cup Maple/Agave
      2 Tablespoons soft coconut oil
      2 Tablespoons Ground Flax Seed combined with 5 table spoons water whisked and set aside
      1 medium apple, diced small (about 1¼ cups)
      1 cup chopped pecans
      ¼ cup flax seeds

      Preheat oven to 350° F and grease a 9 x 13 inch baking pan.
      In a mixing bowl, whisk together the almond flour, coconut, cinnamon, baking soda, and salt.
      Add the applesauce, almond butter, honey, coconut oil, and ground flax mixture. Beat with a mixer until everything is incorporated.
      Stir in the diced apple, pecans, and flax seeds.
      Spread the batter in the prepared pan and bake for 25min
    • Sorry - didnt realize you couldnt see it. Talked about all grains having gluten.  
    • We can't see the video carle.  The site is banned from celiac com for spamming. Not having seen it, I'd guess they are selling something?
    • Sorry Doit, Ok, I think I see what you are talking about.  The serum IgA test?  The serum IgA is to verify if your body does make IgA antibodies.  Not all of us make that particular antibody type.  you do make IgA antibodies though, and your reading is fairly high.  the way I understand it, the serum IgA is not specific to celiac disease.  It does indicate a level of antibody activity though.  So perhaps you are fighting an infection or something?  Or it is celiac and for some reason your blood levels of antibodies are not high enough to detect right now. The below info on serum IgA is from Quest Labs. ******************************************************************** Test Highlight IgA, Serum    Clinical Use Diagnose IgA deficiencies Determine etiology of recurrent infections Diagnose infection Diagnose inflammation Diagnose IgA monoclonal gammopathy Clinical Background IgA is the first line of defense for the majority of infections at mucosal surfaces and consists of 2 subclasses. IgA1 is the dominant subclass, accounting for 80% to 90% of total serum IgA and greater than half of the IgA in secretions such as milk, saliva, and tears. IgA2, on the other hand, is more concentrated in secretions than in blood. IgA2 is more resistant to proteolytic cleavage and may be more functionally active than IgA1. IgA deficiency is the most prevalent isotype deficiency, occurring in 1/400 to 1/700 individuals. Many patients with IgA deficiency are asymptomatic, while others may develop allergic disease, repeated sinopulmonary or gastroenterologic infections, and/or autoimmune disease. Individuals with complete absence of IgA (<5 mg/dL) may develop autoantibodies to IgA after blood or intravenous immunoglobulin infusions and may experience anaphylaxis on repeat exposure. Elevated serum IgA levels are associated with infection, inflammation, or IgA monoclonal gammopathy. Method In this nephelometric method, anti-human IgA binds to IgA in the patient sample, forming an insoluble complex. The amount of light scattered by this insoluble complex is proportional to the concentration of IgA present in the sample.   ********************************************************************
    • Thanks for yoUr response GFinDC. For what it's worth,  I've eaten gluten daily for at a minimum of 10 weeks now. I have to taste at work, and initiallyni noticed no ill effect until after I'd been consuming it regularly over a period of time. Shortly before I initially went gluten free, I was suffering from unexplainable stomach cramping and issues that did go away when I quit gluten. It didn't come back until just the past couple of weeks though and now I'm remembering how painful, uncomfortable, and smelly the whole situation was 😂    Can you explain what the reflex test (the one I tested above range in) is?
