What is an Anti-SS-A/Ro (Antibody Serum Soluble Substance -A Antibody) Test?
The Anti-SS-A/Ro test is a blood test that detects specific antibodies that the immune system produces against certain proteins found inside cell nuclei. Doctors prescribe it when they suspect autoimmune conditions such as Sjögren's syndrome or systemic lupus erythematosus (SLE). A small blood sample is collected from a vein in your arm, and the serum (the liquid portion of blood) is analysed in the laboratory.
What Does an Anti-SS-A/Ro (Antibody Serum Soluble Substance -A Antibody) Test Measure?
The Anti-SS-A/Ro antibody test looks for antibodies directed against the SS-A/Ro antigen complex, a group of proteins found in the cell nucleus. This complex includes two distinct proteins and their associated molecules.
| Component | What it is |
|---|---|
| Ro60 antigen | A 60-kDa protein that helps repair misfolded RNA molecules inside cells |
| Ro52 antigen (TRIM21) | A 52-kDa protein involved in tagging other proteins for degradation within the body |
| SS-A/Ro antibodies | Immune proteins that target the Ro antigen complex; their presence indicates possible autoimmune activity |
Why is an Anti-SS-A/Ro (Antibody Serum Soluble Substance -A Antibody) Test Done?
This test is ordered when a doctor wants to investigate symptoms that may point to an autoimmune condition or to confirm a suspected diagnosis.
Common Symptoms That May Require This Test
Several symptoms may prompt a doctor to request this test. The following are listed in order of how commonly they lead to this investigation.
- Dry mouth causing difficulty chewing or swallowing
- Dry eyes with burning, itching, or a sandy sensation
- Joint and muscle pain without a clear cause
- Persistent fatigue that does not improve with rest
- Skin rashes, particularly on sun-exposed areas
- Photosensitivity (unusual skin reaction to sunlight)
- Blurred vision or light sensitivity
Conditions This Test Can Help Detect
The Anti-SS-A/Ro test can support the diagnosis of several autoimmune conditions.
- Sjögren's syndrome: anti-Ro/SS-A antibodies are found in 60 to 70% of primary Sjögren's syndrome patients
- Systemic lupus erythematosus (SLE): detected in 35 to 60% of active SLE cases
- Rheumatoid arthritis
- Systemic sclerosis (scleroderma)
- Idiopathic inflammatory myopathies (muscle inflammation disorders)
- Interstitial lung disease (scarring and inflammation of lung tissue), especially in patients with isolated anti-Ro52 antibodies
- Neonatal lupus and congenital heart block in infants born to affected mothers
Anti-SS-A/Ro (Antibody Serum Soluble Substance -A Antibody) Test During Pregnancy
A positive Anti-SS-A/Ro antibody result in a pregnant woman with SLE may indicate an increased risk of congenital heart block in the newborn. Maternal anti-SSA/Ro antibodies cross the placenta and can affect the developing foetal heart, sometimes causing complete congenital heart block. Echocardiographic (heart ultrasound) monitoring every two weeks from 16 weeks to at least 24 weeks of pregnancy is generally recommended for anti-SSA-positive women.
Anti-SS-A/Ro (Antibody Serum Soluble Substance -A Antibody) Test for Chronic Disease Monitoring
Elevated anti-SS-A/Ro antibody levels closely reflect the activity of Sjögren's syndrome and related autoimmune conditions. When treatment is effective and the disease enters remission, antibody levels typically decline. The test may be repeated periodically to track disease activity and how well treatment is working.
How to Prepare and What to Expect
No complex preparation is needed for this test. A few simple steps can help ensure a smooth experience.
Do You Need to Fast?
No, fasting is not required before the Anti-SS-A/Ro test. You may eat and drink normally before your appointment. If additional tests have been ordered at the same time, check with your doctor whether any of those require fasting.
Practical Tips Before Your Test
Follow these practical steps before your test appointment.
- Bring a detailed clinical history, including your symptoms, previous test results, and any relevant medical records, as this is required for the test
- Inform your doctor about all medications, supplements, immunosuppressants, steroids, or biologic drugs you are currently taking, as these may influence results
- Stay well-hydrated before your appointment to make blood collection easier
- Wear comfortable clothing with easy access to your arm for the blood draw
Step-by-Step Procedure
Here is what to expect during the sample collection.
- A trained phlebotomist (blood collection specialist) cleans the skin over a vein, usually on your inner arm.
- A small blood sample of approximately 3 ml is drawn using a fine needle into a gel tube.
- You may feel a brief pinch during the draw; minor bruising at the collection site is normal and usually clears within a day or two.
- The needle is removed, and light pressure is applied to stop any bleeding.
- The sample is labelled correctly and stored under refrigeration (2 to 8°C) to preserve it.
- The sample is dispatched to the laboratory, where it is tested using EIA (Enzyme Immunoassay), a method that detects and measures specific antibodies.
Factors That Can Affect Accuracy
Certain conditions and practices can influence the reliability of your results.
- Haemolysis (rupture of red blood cells) in the sample, which can occur if blood is handled roughly
- Lipaemia (high fat content in blood) at the time of collection
- Improper sample storage or delays in processing
- Current use of immunosuppressive medications or steroids
- Active or recent infections that may temporarily raise antibody levels
Understanding Your Anti-SS-A/Ro (Antibody Serum Soluble Substance -A Antibody) Test Results
Your results will indicate whether anti-SS-A/Ro antibodies were detected in your blood sample. Always review your report with your doctor, who will interpret the findings alongside your symptoms and medical history.
| Parameter | Result | Interpretation |
|---|---|---|
| Anti-SS-A/Ro antibodies | Less than 1.0 U (Negative) | No significant antibodies detected; lower likelihood of associated autoimmune conditions |
| Anti-SS-A/Ro antibodies | 1.0 U or above (Positive) | Antibodies detected; may suggest Sjögren's syndrome, SLE, or another connective tissue disease |
These ranges are general guidelines. Your doctor will interpret your results based on your age, health history, and other factors. Always consult a qualified healthcare professional for personalised medical advice.
Results During Special Conditions
Certain circumstances can affect how results are interpreted.
Recent infections or other active autoimmune diseases may cause a temporary rise in anti-SSA/Ro antibody levels, even in people who do not have Sjögren's syndrome or SLE.
Some patients recovering from SARS-CoV-2 (COVID-19) infection have also shown positive anti-SSA/Ro results. Immunosuppressive medications can suppress antibody levels, potentially affecting the accuracy.
How to Maintain Healthy Levels
These general wellness tips may support overall well-being, particularly for individuals who are anti-Ro positive.
- Attend regular follow-up appointments with your rheumatologist or physician if you have a known autoimmune condition
- Protect your skin from excessive sun exposure by using sunscreen and wearing protective clothing, as photosensitivity is common in anti-Ro positive individuals
- Stay well-hydrated and discuss options such as lubricating eye drops with your doctor if you experience dryness symptoms

Frequently Asked Questions
The Anti-SS-A/Ro test detects autoantibodies directed against SS-A/Ro proteins inside cell nuclei. It is commonly used to investigate suspected autoimmune conditions, particularly Sjögren's syndrome and systemic lupus erythematosus. Doctors may order it when a patient presents with dry eyes, dry mouth, joint pain, or unexplained fatigue.
A positive Anti-SS-A/Ro antibody result does not automatically confirm an autoimmune disorder. Further evaluation by a doctor is always required to understand the significance of a positive result. Antibodies can occasionally be elevated due to infections or other temporary factors.
Anti-SSA/Ro antibodies can cross the placenta and affect the developing foetal heart, potentially causing congenital heart block (a condition where electrical signals in the heart do not pass correctly). Pregnant women who test positive are typically monitored with regular foetal heart scans. Early detection allows doctors to take appropriate steps to protect the baby.
No fasting is required for this test. You can eat and drink as usual before your appointment. If your doctor has ordered other tests at the same time, confirm whether those have specific fasting requirements.
Isolated anti-Ro60 antibodies are more closely associated with SLE, while the presence of both Ro52 and Ro60 antibodies together is strongly linked to Sjögren's syndrome. Patients with only anti-Ro52 antibodies tend to show a higher rate of inflammatory muscle conditions, systemic sclerosis, or interstitial lung disease. Your doctor will consider which antibodies are detected when interpreting your results.
Doctors often order related tests to build a fuller picture of autoimmune activity. These may include ANA (antinuclear antibody), Anti-dsDNA, Anti-SS-B/La antibody, ESR (erythrocyte sedimentation rate), and CRP (C-reactive protein) tests.
Results for the Anti-SS-A/Ro test at Lupin Diagnostics are typically available within 3 days. Turnaround times may vary slightly depending on the location and laboratory workload.
