Hi
Blood tests alone are not the accepted criteria anymore for Sjogrens, according to the ACR-EULAR Classification Criteria. A positive lip biopsy, Anti-SSA that is positive, Schirmer's test and salivary flow test are some of the other tests. I had a negative SSA, but a positive lip biopsy and all other positive criteria.
It is discouraging that some people (and doctors, sadly) don't realize that this disease should never be diagnosed based on blood tests alone.
Here is a great resource https://www.sjogrensadvocate.com/
This website is run by a doctor with Sjogrens and you will learn a lot about the myths and misunderstandings of this complex autoimmune disease.
Its important to find a good rhemetologist, and it sometimes takes awhile to find a well-informed doctor.
I wish you the best and know that you are not alone!
The Sjogren's Foundation also has some good articles and information. Their website is: https://sjogrens.org/understanding-sjogrens
