No: This is not a typical symptom of celiac disease. More common would be diarrhea, loose, watery stools, and failure to gain weight. Tarry stools is a symptom of intestinal bleeding. ...Read more

Gastrointestinal Bleeding (Definition)

A long tube runs from the mouth to the anus. It includes, in order, the mouth, throat, esophagus, stomach, small intestine (duodenum, jejunum, ileus), caecum, the ascending, transverse, descending, and sigmoid colon (or large intestine) and the rectum. The space inside that tube, the lumen, is considered to be outside of the body. When we bleed into that space ...Read more

My endoscopy biopsy looked exactly like something caused by Celiac disease but my blood test came back negative, what else could it be?

My endoscopy biopsy looked exactly like something caused by Celiac disease but my blood test came back negative, what else could it be?

Biopsy definitive.: In regards to celiac disease, the biopsy is more diagnostically reliable than the blood test, so if the blood test showed typical evidence of celiac disease, I'd believe it. ...Read more

Two negative blood test for celiac disease is it possible to still have it and it be the cause of bone loss? How do I test and make sure 100%

Two negative blood test for celiac disease is it possible to still have it and it be the cause of bone loss? How do I test and make sure 100%

There's no 100%: The labs are probably not totally sensitive / specific but they're pretty good. Have you had a biopsy? This is one to work out with your physician. Bone loss won't be the primary manifestation of celiac disease despite "pop" wisdom. "Low blood pressure" isn't an illness. A full workup, including some zebras like porphyria or other neuropathies, may be a consideration along with supportive Dr. ...Read more

Very high B12 blood level, low iron, rt side ab pain despite very strict gfdiet for celiac disease, not on vitamins. What could cause high B12 levels?

High B12 and folate (folic acid): Levels are caused by their accumulation and non use in the body. I have seen it related to vitramin b1 deficiency. Worth trying. ...Read more

Daughter diagnosed with Celiac Disease 8 weeks ago. Now has severe itching on lower legs only at night time. Low white blood count and high Globulin Serum levels. Severe weight loss, and bruising What could cause this? Itching Issues

There is a very: Characteristic skin rash that accompanies celiac disease: dermatitis herpetiformis. Typically this is a skin manifestation of non-celiac wheat sensitivity. Extremely itchy bumps or blisters appear, especially on the forearms. The lab abnormalities you describe are not typical for celiac; in fact serum globulins may be low. I suspect more than one diagnosis; continue working closely with her Doctor ...Read more

Does anal fissure or what disease cause headaches / Stress / loss appetite / itchy after stool / sometimes blood in stool / stressing out about it?

Does anal fissure or what disease cause headaches / Stress / loss appetite / itchy after stool / sometimes blood in stool / stressing out about it?

Different conditions: An anal fissure or hemorrhoids can cause blood in stool and anal pruritus or itchiness. The headaches and stress may be due to a different condition. A possible link would be through a degree of anemia if the rectal bleed has been going on for a while. Stress is the disease of the century and lifestyle changes are usually necessary. Talk to your doc about your symptoms at next visit. ...Read more

If one tests negative for wheat blood allergy test, does this mean no chance of celiac disease?

If one tests negative for wheat blood allergy test, does this mean no chance of celiac disease?

No, definite chance: Blood tests for wheat allergy measure IgG and/or IgE antibodies to proteins in wheat (which may include gluten) but not everyone with celiac disease will have these antibodies. The best blood test is IgA anti-tissue transglutaminase. If you really want to rule out celiac disease you should get that test- but only after eating gluten!

I have not checked for Celiac disease. Should I get a blood test? I have been under a lot of stress lately. I also drink a lot of caffeine.

I have not checked for Celiac disease. Should I get a blood test? I have been under a lot of stress lately. I also drink a lot of caffeine.

Maybe: Your question does not provide enough info to confirm or exclude need for a celiac screening. It is a real problem with some subtle symptoms and effects. Screening is simple but confirmation requires an intestinal biopsy. You should have it confirmed before trying a gluten free lifestyle, which has a cult like following. True celiacs have other associated risks that need to be explored. ...Read more

What are the tests for celiac disease? Blood?

What are the tests for celiac disease? Blood?

Anti-tTG first: In suspected celiac disease / gluten enteropathy / sprue, the cheap screening test is the anti-ttg (tissue transglutiminase); followup may include the more costly IgA anti-endomysial antibdies (ema), biopsy of the gut, and/or a trial of a gluten-free diet. No one knows how common celiac disease really is; what matters is whether gluten elimination ultimately helps you. ...Read more

Celiac disease blood testing involves what tests usually?

TTG IgA, others: Arguably the most accurate is the ttg IgA level. In those who are IgA deficient, I believe a dpg igg is the best. Others include anti-endomysial antibodies. The gold standard is duodenal biopsies obtained during endoscopy. ...Read more

How accurate is the blood test for celiac disease?

Not very: It is perhaps about 50% accurate. We believe it when positive but not when negative. Even biopsy can miss the diagnosis. Best to test celiac genetic panel. Mayo lab and enterolab can do this. Google enterolab and order the test yourself $150. ...Read more

Celiac disease and having green stools, is this normal?

Green=fast: Green stools could mean your food is traveling thru your GI tract faster than usual. It might be time to visit your dr and have a blood test to monitor your antibodies for celiac. If they are elevated from last test, this could mean, your diet has some gluten in it, that might be affecting the transit of your stool. Also check your weight, and stool for fat. ...Read more

My doc ordered 4 blood tests testing for celiac disease. I live in rural Iowa. They had to sent to Mayo. Why is this? What are the tests?

My doc ordered 4 blood tests testing for celiac disease. I live in rural Iowa. They had to sent to Mayo. Why is this? What are the tests?

Varies: There are a number of tests that are used to screen for celiac disease. The tissue transglutaminase IGA is one of the more dependable, usually ordered with an IGA level. There are others, and the delicate nature of the tests requires that they be done in a facility that does them often to be reliable. Local hospitals rarely have the volume to invest in the specialized equipment. ...Read more

Is it possible for a toddlers blood test to be negative for celiac disease but upon endoscopy or colonoscopy be found to indeed have celiac disease?

Is it possible for a toddlers blood test to be negative for celiac disease but upon endoscopy or colonoscopy be found to indeed have celiac disease?

Possibly: If the correct test was done (measurement of IgA antibody to human recombinant TTG is recommended for initial testing for CD by NASPGHAN) and was negative, AND if a child has chronic diarrhea or failure to thrive OR if they have selective IgA deficiency or a + family hx of CD, a biopsy might be recommended. Consult with a pediatric GI physician if this is the case. Best of luck! ...Read more

Is it absolutely impossible to have celiac disease without positive blood tests and biopsy? Even with all symptoms and other autoimmune diseases?

Very unlikely: The gold standard of celiac disease is the small bowel biopsy. Blood tests, if positive are helpful. You don't provide enough clinical detail to give you more specific advice. Denmark has several excellent hospitals and medical schools. I suggest you should be evaluated in a tertiary medical center. L ...Read more
