How Is Sjogren's Disease Tested? Blood Tests, Lip Biopsy, Ultrasound & More

If you suspect you might have Sjogren’s disease, one of your first questions may be: What tests do doctors use to check for Sjogren’s disease?

Maybe you’re experiencing dry eyes, dry mouth, unexplained fatigue, joint pain, or neurological symptoms. Perhaps your doctor has already ordered blood work, but the results haven’t provided clear answers. Or maybe you’ve heard about a lip biopsy, salivary gland ultrasound, or specialized antibody panel and aren’t sure what these tests involve.

There is no single test that can reliably confirm or rule out Sjogren’s disease in every patient. Sjogren’s is a systemic autoimmune disease, and testing often involves several pieces of information. Understanding what each test measures can help you have more informed conversations with your healthcare team.

1. What Blood Tests Are Used for Sjogren’s Disease?

Blood tests are often the starting point. They look for antibodies and other findings that may support an autoimmune diagnosis.

Anti-SSA/Ro Antibodies

Anti-SSA, also called anti-Ro, is one of the most important tests associated with Sjogren’s disease. A positive result provides supporting evidence, particularly alongside compatible symptoms and objective findings. SSA antibodies also occur in other autoimmune diseases, including lupus. You can have Sjogren’s disease even if your SSA test is negative.

Anti-SSB/La Antibodies

Anti-SSB, also called anti-La, is another associated antibody. Some people test positive for both SSA and SSB. An isolated positive SSB result without SSA is not enough on its own to meet established Sjogren’s classification criteria.

ANA (Antinuclear Antibodies)

ANA may be positive in Sjogren’s disease, other autoimmune conditions, and sometimes people without autoimmune disease. A negative ANA does not automatically exclude Sjogren’s disease.

Rheumatoid Factor (RF)

Rheumatoid factor may be positive in Sjogren’s disease and does not necessarily mean someone has rheumatoid arthritis.

Other Blood Tests

Depending on symptoms, clinicians may order:

  • Complete blood count (CBC)

  • Comprehensive metabolic panel (CMP)

  • ESR and CRP inflammatory markers

  • Complement levels, including C3 and C4

  • Immunoglobulin levels

  • Thyroid function testing

These help assess overall health, inflammation, organ function, and alternative causes. They do not independently diagnose Sjogren’s disease.

2. What Is the Early Sjogren's Antibody Panel?

Some patients encounter the Early Sjogren’s Syndrome Profile, sometimes called the early Sjogren’s antibody panel. It measures antibodies such as salivary protein-1 (SP1), carbonic anhydrase VI (CA6), and parotid secretory protein (PSP). Researchers have investigated whether these markers might help identify earlier disease, but they have not demonstrated sufficient diagnostic reliability for routine use. They are not included in established classification criteria, and British Society for Rheumatology guidance does not recommend novel Sjogren’s antibodies for routine diagnosis outside research. Positive results do not confirm the disease, and negative results do not rule it out.

3. What Is the AVISE Test?

AVISE CTD is a specialized blood-testing panel offered by Exagen to help clinicians evaluate autoimmune connective tissue diseases, especially when symptoms overlap. Its Sjogren’s-related testing includes anti-SSA/Ro52, anti-SSA/Ro60, and anti-SSB/La antibodies. AVISE may provide additional information in selected patients, but it is not a standalone Sjogren’s diagnostic test and is different from the early antibody panel. Ask what information it may add beyond testing already completed.

4. What Eye Tests Are Used for Sjogren's Disease?

An ophthalmologist can assess tear production and whether dryness has affected the eye surface.

Schirmer’s Test

Small strips of specialized paper are placed near the lower eyelids, usually for five minutes, to measure tear production.

Ocular Surface Staining

Special dyes help an eye specialist identify surface changes associated with dryness, sometimes recorded using an ocular staining score. Abnormal findings on either test are not specific to Sjogren’s disease.

5. How Is Saliva Production Tested?

An unstimulated salivary flow test, also called sialometry, measures how much saliva a person produces without stimulation over a specified period. Low flow can support evidence of salivary gland dysfunction. Dehydration and medications, including some antihistamines and antidepressants, can also reduce saliva. Do not stop prescribed medications without discussing them with your clinician.

6. What Is a Lip Biopsy for Sjogren's Disease?

A minor salivary gland biopsy, commonly called a lip biopsy, removes a small sample of salivary gland tissue from inside the lower lip. A pathologist examines it for characteristic inflammation.

What Is a Focus Score?

A focus score describes clusters of inflammatory cells in a defined area of gland tissue. A score of at least one, with characteristic findings, is an important part of established classification criteria.

Does Everyone Need a Lip Biopsy?

No. It may be especially useful when symptoms suggest Sjogren’s disease but anti-SSA is negative. Decisions depend on the individual case. Risks include discomfort, bleeding, infection, and occasionally persistent numbness or altered sensation. Tissue sampling and pathology expertise also matter. Ask: How would the result change my evaluation or care?

7. Can Salivary Gland Ultrasound Detect Sjogren's Disease?

Salivary gland ultrasound is noninvasive imaging of major glands, especially the parotid and submandibular glands. Trained clinicians look for structural changes that may be associated with Sjogren’s disease. Ultrasound can provide useful additional information but does not independently establish a diagnosis. As of October 2026, it is not part of the 2016 ACR/EULAR classification score and does not formally replace antibody testing or biopsy within that framework. Availability and expertise vary.

8. Clinical Diagnosis Versus Classification Criteria: Why the Difference Matters

A clinical diagnosis is made by a qualified healthcare professional considering symptoms, history, examination, tests, and alternative explanations. Classification criteria are standardized rules designed primarily for research and clinical trials.

The 2016 ACR/EULAR criteria assign points to these findings:

Test or finding

Points

Positive anti-SSA/Ro antibodies

3

Characteristic lip biopsy with focus score ≥1

3

Ocular staining score ≥5, or equivalent specified threshold

1

Schirmer’s test ≤5 mm in five minutes

1

Unstimulated salivary flow ≤0.1 mL/min

1

For eligible individuals without specified exclusion conditions, a score of four or more meets the classification threshold. Eligibility and exclusions also matter. Classification criteria are not mandatory diagnostic rules for every patient: someone may receive a clinical diagnosis without meeting the research threshold, and a numerical score does not replace medical judgment.

9. How Is Sjogren's Disease Tested in Children?

Sjogren’s disease can affect children and adolescents, but its presentation may differ from adults. One important warning sign is recurrent swelling of the salivary glands, particularly the parotid glands in front of the ears and along the jaw. Swelling may occur on one or both sides, may be painful, and may precede noticeable dry eyes or dry mouth.

Recurrent gland swelling does not automatically mean Sjogren’s disease. Other causes, including juvenile recurrent parotitis and infections, must be considered.

What Tests Are Used for Pediatric Sjogren’s Disease?

  • Blood tests: SSA/Ro, SSB/La, ANA, and other laboratory studies
  • Salivary gland ultrasound: noninvasive imaging for gland changes
  • Eye examinations: Schirmer’s testing and ocular surface evaluation when appropriate
  • Salivary flow testing: measurements of saliva production
  • Minor salivary gland biopsy: considered in selected cases

Ultrasound may be especially helpful to consider in children because it is noninvasive and can help assess recurrent gland swelling. The 2016 ACR/EULAR classification criteria were developed and validated primarily for adults and may not fully capture pediatric presentations. There are no universally accepted, validated pediatric-specific classification criteria. Evaluation by a pediatric rheumatologist familiar with the disease may be valuable. Absence of classic dryness or positive antibodies should not automatically end an appropriate evaluation.

10. What If Your Sjogren's Tests Are Negative?

Some people have seronegative Sjogren’s disease, meaning they lack detectable disease-associated antibodies, particularly anti-SSA/Ro. Depending on the clinical picture, a rheumatologist may consider objective eye tests, salivary flow testing, ultrasound, or lip biopsy. Negative results also make it important to investigate other possible causes. The next step depends on the full clinical picture, not one laboratory result.

11. Can Sjogren's Disease Affect More Than Your Eyes and Mouth?

Yes. Sjogren’s is systemic. Some people experience fatigue, joint pain, or neurological symptoms, including tingling, numbness, burning sensations, or autonomic nervous system problems. These symptoms have many possible causes and deserve appropriate evaluation.

12. Questions to Ask Your Rheumatologist About Sjogren's Testing

  1. Which Sjogren’s blood tests have I already had?
  2. What do my antibody results mean?
  3. Should I have objective eye or salivary flow testing?
  4. Could my medications or another condition explain my symptoms?
  5. Would ultrasound or a lip biopsy provide useful information?
  6. How are you interpreting these results for a clinical diagnosis?
  7. If testing remains inconclusive, what happens next?

You don’t need to know which test to request before seeing your doctor. Understanding the options can help you participate more confidently in the conversation.

The Bottom Line: How Is Sjogren’s Disease Tested?

Testing may involve blood work, eye examinations, saliva measurements, salivary gland imaging, and sometimes lip biopsy. Not everyone needs every test, and results don’t always provide a straightforward answer. In children, recurrent salivary gland swelling may be an important reason to investigate even without classic dryness. The key is understanding what each test measures, its limitations, and how the findings fit together. Ask which tests you’ve completed, what the results suggest, and whether further evaluation is appropriate.
