How is Sjogren diagnosed?

Diagnosis of Sjogren is a multi-faceted process typically conducted by a rheumatologist, involving a combination of clinical evaluations, serological blood testing, and objective assessments of glandular function.

The Diagnostic Process

Because Sjogren is a systemic autoimmune disease, it often presents with vague symptoms that overlap with other conditions, leading to a notoriously long "diagnostic odyssey." Many patients spend years visiting various specialists before receiving a definitive answer. A rheumatologist will generally follow the 2016 ACR/EULAR classification criteria, which weigh several factors, including:

• Serology: Testing for specific autoantibodies, primarily anti-SSA (Ro) and anti-SSB (La).


• Ocular Assessment: Using tests like the Schirmer’s test or ocular surface staining to quantify dry eyes.


• Glandular Assessment: Measuring unstimulated whole salivary flow or performing a minor salivary gland biopsy to check for focal lymphocytic sialadenitis.


• Clinical History: Assessing the presence of oral dryness, joint pain, and fatigue.

Differential Diagnosis and Specialist Care

Sjogren is frequently misdiagnosed as fibromyalgia, chronic fatigue syndrome, or lupus due to the shared experience of systemic inflammation. It is vital to consult a rheumatologist who specializes in autoimmune connective tissue diseases. If your primary care physician or ophthalmologist suspects Sjogren, do not be discouraged if the initial workup is inconclusive; the disease can evolve, and repeat testing may eventually be necessary to confirm the diagnosis.

We understand that the path to a Sjogren diagnosis can be physically and emotionally exhausting. Being dismissed or told your symptoms are "all in your head" is a painful experience shared by many in our community. Please know that your symptoms are real, and continuing to advocate for a referral to a specialized center is a crucial step in managing this complex condition.
