Once you are diagnosed with celiac disease, it is important that first-degree relatives (parents, siblings, children) undergo the study to rule out that they do not suffer from it.

Your family doctor can perform the study, which would consist of:

Performing an analysis with antitransglutaminase IgA and total IgA and genetic study of HLA DQ2 and DQ8 on all first-degree relatives of the patient.
