The epithelial cells in the salivary glands are active participants in the autoimmune-mediated process of Sjögren’s syndrome, and TNF-α levels are increased in that disease. (12,13) Relationships between TNF-α levels in blood and saliva are not fully understood.

Considerations for adding Salivary DNA to analyte Studies:
You can combine salivary analytes with easy, accurate, and affordable genomic testing using Salimetrics SalivaLab and the same sample that you are already collecting – no specialized saliva collection devices or additional samples are required.
Don’t know what SNPs are right for you? The SalivaLab’s DNA team specializes in genetic testing services, we recommend you Request a DNA Consult (gratis) to learn more about common considerations such as # of samples, participant ethnicity, and IRB Approval.
