celiac scale

[Mac63]

hello i just got  tested  because  my  sister  has celiac. I'm in Winnipeg  Mb and i was told their  scale   is  0-19,they told me  my  number is 22,so what does  that all mean, could i have also   received a false positive result, for  i  know that even though i may  not have any symptoms that  i still can have celiac and should stop all  gluten.

Welcome to the forum, Mac63!

The scale that you supplied and the result . . . for which celiac antibody test is that for? Do you have the name of the test? Some antibody tests for celiac disease are more specific than others. More than than likely, it was the tTG-IGA test as that is the most common one physicians order initially.

This article might be helpful. It breaks down each type of test, and what a positive results means in terms of the probability that you might have celiac disease. One test that always needs to be done is the IgA Levels/Deficiency Test (often called "Total IGA") because some people are naturally IGA deficient, and if this is the case, then certain blood tests for celiac disease might be false-negative, and other types of tests need to be done to make an accurate diagnosis. The article includes the "Mayo Clinic Protocol," which is the best overall protocol for results to be ~98% accurate.
