What is SSA 52 blood test?
SSA-52 (Ro52) and/or SSA-60 (Ro60) antibodies are associated with a diagnosis of Sjögren syndrome, systemic lupus erythematosus (SLE), and systemic sclerosis. SSA-52 antibody overlaps significantly with the major SSc-related antibodies.
What is the normal range for SSA antibody?
Table 1
| 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 |
What is RO 52 antibody positive?
Ro52 is an interferon-inducible protein of the tripartite motif family. Antibodies against Ro52 have been described in patients with different autoimmune diseases, such as systemic lupus erythematosus and Sjögren’s syndrome, that are often associated with anti-Ro60 antibodies.
What does high Sjogren’s Anti-SSA mean?
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 antibodies are high in Sjogren’s?
The antibodies associated with Sjogren’s include anti-Ro (SS-A) and anti-La (SS-B) antibodies, rheumatoid factor, and antinuclear antibodies.
What is a positive result for Sjogren’s?
Antinuclear Antibody (ANA): The ANA test is positive in the majority of Sjögren’s syndrome patients. However, a positive ANA test is also common in healthy individuals. The ANA test is most commonly performed using a technique that involves immunofluorescent staining of human cells grown in tissue culture (Figure 3).
What does positive Ro antibodies mean?
A positive result for SS-A/Ro antibodies is consistent with connective tissue disease, including Sjogren syndrome, lupus erythematosus (LE), or rheumatoid arthritis. A positive result for SS-A/Ro antibodies in a woman with LE prior to delivery indicates an increased risk of congenital heart block in the neonate.
What is connective tissue disease?
A connective tissue disease is any disease that affects the parts of the body that connect the structures of the body together. Connective tissues are made up of two proteins: collagen and elastin. Collagen is a protein found in the tendons, ligaments, skin, cornea, cartilage, bone and blood vessels.
Which is worse lupus or rheumatoid arthritis?
So, is RA Worse than Lupus? To answer the original question, neither disease is “worse” than the other, but they are different, and require treatment accordingly. Patients with each diagnosis can have a mild or severe form of either disease.
What were your first symptoms of Sjögren’s?
The two main symptoms of Sjogren’s syndrome are:
- Dry eyes. Your eyes might burn, itch or feel gritty — as if there’s sand in them.
- Dry mouth. Your mouth might feel like it’s full of cotton, making it difficult to swallow or speak.
