Gastroenterology blood work / Celiac disease

Doctors called me regarding my son blood work and they said if something came back abnormal they will contact me. I missed the call today and it was late by the time I called them back to review his results. lm pretty nervous they did blood work to check for Celiac disease

I'm worried and im trying to fine answers I can't wait until tomorrow.

Anyone who had done Celiac disease tesr and test came back abnormal what is the next step you or child had to take ??

Some test are still under review
