Is it safe for a person with celiac disease to donate blood?

Is it safe for a person with celiac disease to donate blood?

Sure, if not anemic: Celiac sprue isn't "catching"; you're blood is not tainted by infection.. If you don't have iron deficiency or anemia (both not uncommon in celiac), then yes you could donate blood, and thank you for doing it. ...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

How accurate is the blood test for celiac disease?

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

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

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

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

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

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
