THYROTROPIN RECEPTOR ANTIBODIES IN PAROTID-SALIVA

Parotid saliva was collected with a Carlson-Crittenden device, under c itric acid stimulation, in 18 patients with autoimmune thyroid disease . Thyrotropin Receptor Antibodies (TRAb) were measured with a radiorec eptor assay in parotid saliva and in serum in the same patients, and a statistical analysis of the data was performed. TRAb levels in paroti d saliva were higher than in serum in the 3 pathologies studied (Grave s' disease, Hashitoxicosis and Hashimoto's thyroiditis). There was goo d correlation between salivary and serum levels.
