Yep, blood tests are good but not perfect.

I used to hear in a perfect world that anti-endomysial and anti-tTG should be consistent, but they aren't always. Which is why a thorough doctor will run them all. I know in our case, only the anti-tTG was run, yet I believe it can go both ways (negative anti-tTG and positive anti-endomysial)

It is also why it makes me a little crazy that some of our major celiac centers (like a very windy one) suggest all is needed is a single anti-tTG test.

Recommendations for testing come down to picking what is considered the BEST TEST OVERALL to contain cost, but it is a shame that it comes down certain people falling through the cracks because no test is 100% accurate.
