Diagnosis and further testing Celiac

[Redanafs]

Hi everyone. Back in 2022 I had blood work drawn for iga ext gliadin. Since then I’ve developed worse stomach issues and all other health issues. My doctor just said cut out gluten. He did no further testing. Please see my test results attached. I just need some direction cause I feel so ill and the stomach pain is becoming worse. Can this test show indications for other gastrointestinal diseases?

It's strange to see two very different results in what appears to be a single blood test--one is positive and one is negative for a celiac disease test. Are these results separated by time?

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.

The DGP-IgA test is considered to have high sensitivity and specificity. In general, the DGP-IgA test has been reported to have a sensitivity ranging from 75% to 95% and a specificity ranging from 90% to 100%. Overall, the DGP tests, including DGP-IgA and DGP-IgG, exhibit a sensitivity of approximately 85-95% and a specificity of about 95-98%.

That is very strange, because it looks to me like two very different test results, but for the same test! It's definitely time to contact your doctor for clarity on this.
