What does a positive SS-A antibody mean?
A positive result for SSA (Ro) or SSB (La) antibodies is consistent with connective tissue disease, including Sjogren syndrome, lupus erythematosus (LE), or rheumatoid arthritis.
What are SS-A and SS-B antibodies?
INTRODUCTION. Anti‐SSA and ‐SSB antibodies are clinically important antinuclear antibody (ANA) in patients with systemic rheumatic diseases. These antibodies are found in Sjögren’s syndrome (SS), as well as other systemic autoimmune diseases (ADs), such as systemic lupus erythematosus (SLE), myositis, scleroderma, etc.
What is a SS-A blood test?
Useful For. Suggests clinical disorders or settings where the test may be helpful. Evaluating patients with signs and symptoms of a connective tissue disease in whom the test for antinuclear antibodies is positive, especially those with signs and symptoms consistent with Sjogren syndrome or lupus erythematosus.
What does a positive Sjogren’s antibody test mean?
What does it mean to have elevated Sjögren’s antibodies? Elevated Sjögren’s antibodies—anti-SS-A and anti-SS-B—are suggestive of inflammatory connective tissue disease. Elevated results on this test may indicate Sjögren’s syndrome or another autoimmune disease such as lupus or rheumatoid arthritis.
Does positive SSA mean lupus?
In pregnant women, a positive Anti-Ro(SSA) or Anti-La(SSB) warns doctors of the need to monitor the unborn baby. Limitations of the test: Like other antibodies, the fact that the test is not positive in many people with lupus means it can’t be used to diagnose lupus.
What is the normal range for SSA antibody?

Case 1 | Normal range | |
---|---|---|
Anti-SSA/Ro52・Ro60 antibodies (anti-SSA/Ro antibodies) | 203 | < 10 U/mL |
Anti-SSB/La antibodies | < 1.0 | < 10 U/mL |
Anti-Scl-70 antibodies | 10.7 | < 10 U/mL |
Rheumatoid factor (RF) | 16 | < 15 U/mL |
Does positive SS-A mean lupus?
What is the normal range for SS-A antibody?
Does everyone have Sjogren’s antibodies?
SS-B antibodies are less common, being found in approximately 30-50% of Sjögren’s syndrome patients. SS-A antibodies thus occur commonly by themselves. However, it is very uncommon for SS-B antibodies to occur alone. Accordingly, 20-40% of Sjögren’s syndrome patients may lack SS-A and/or SS-B antibodies.
Can you have Sjogren’s antibodies and not have Sjogren’s?
SS-A antibodies thus occur commonly by themselves. However, it is very uncommon for SS-B antibodies to occur alone. Accordingly, 20-40% of Sjögren’s syndrome patients may lack SS-A and/or SS-B antibodies. The finding of SS-A and/or SS-B antibodies is not specific to Sjögren’s syndrome patients.
Can you have Sjogren’s without lupus?
Sjogren’s syndrome can occur alone or in association with other autoimmune diseases, most commonly lupus and rheumatoid arthritis (RA). Several studies have shown various differences between people with SS alone and those with SS and another connective tissue disease.
What happens if Sjogren’s is left untreated?
Sjogren’s comes with serious complications if left untreated, including: an increased risk of lymphoma and multiple myeloma. oral yeast infections. dental cavities.
What does a sjogrens flare feel like?
Joint pain is one of the most common symptoms of Sjögren’s syndrome. Multiple joints are painful, usually episodically with periods of joint pain, known as “flares”, followed by periods of little or no joint pain. Tenderness and swelling of the joints, when present, are indicative of inflammatory arthritis.
How does rheumatoid arthritis affect eyes?
The most common eye-related symptom of rheumatoid arthritis is dryness. Dry eyes are prone to infection, and if untreated, severe dry eyes can cause damage to the cornea, the clear, dome-shaped surface of the eye that helps your eye focus.
What is a positive anti – SSA antibody?
See Connective Tissue Disease Cascade (CTDC) in Special Instructions. A positive result for SSA (Ro) or SSB (La) antibodies is consistent with connective tissue disease, including Sjogren syndrome, lupus erythematosus (LE), or rheumatoid arthritis.
What does SSA positive mean?
