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.

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

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 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.
