I recently had blood work done to check my thyroid and to test me for celiac. My labs are back and overall look good except for concern of celiac as stated in an email from my doc. My tranglutaminase ab value is 29.8. Does this mean Celiac? Also, we are waiting on one lab still, and ana titer, which was "sent for supplemental screening". I see this on the net as a test for Lupus. Is the ana titer screening also run to test for Celiac Disease? I'm confused why I would be tested for Lupus if there is a concern for Celiac. Any insight would be greatly appreciated.
