ANTI-SCL-70 Antibody Test: A Marker for Scleroderma and Autoimmune Conditions
The Anti-Scl-70 antibody test is a blood test used to detect the presence of antibodies against the Scl-70 protein (topoisomerase I), which is often associated with systemic sclerosis (scleroderma). It helps in diagnosing and monitoring the progression of this autoimmune disease, particularly the form known as diffuse systemic sclerosis. The test is typically used when a doctor suspects an autoimmune disorder affecting the skin and internal organs.

How our test process works!
Overview:
- Anti-Scl-70 is a type of autoantibody, which is an antibody that mistakenly targets the body's own tissues.
- Elevated levels of anti-Scl-70 antibodies are typically associated with systemic sclerosis, a chronic autoimmune disease that causes the skin and internal organs to become stiff and thickened.
- It is often ordered when a patient presents with symptoms suggestive of scleroderma, including skin thickening, joint pain, difficulty swallowing, and lung involvement.
Risk Assessment:
- Indications for testing:
- Patients showing symptoms of systemic sclerosis or scleroderma, including Raynaud's phenomenon (cold fingers and toes), skin thickening, lung fibrosis, and gastrointestinal issues.
- Testing may be part of a broader panel to assess for autoimmune conditions.
- Risk Factors:
- Women are more likely to develop scleroderma, particularly in the age range of 30-50 years.
- A family history of autoimmune diseases may increase risk.
Normal Range:
- Normal range: Typically, < 1:80 or < 0.5 U/mL, depending on the laboratory and the assay method used.
- Note: Different labs may use different methods, so it is important to consult with the lab's reference range to interpret the result accurately.
Interpretation:
- Positive result:
- Elevated levels of anti-Scl-70 antibodies are strongly associated with diffuse systemic sclerosis (a more aggressive form of scleroderma), which involves the skin and internal organs like the lungs, heart, and kidneys.
- A positive result can indicate that the individual may be at risk for lung fibrosis and other organ complications.
- Negative result:
- A negative test result does not entirely rule out systemic sclerosis but suggests that the disease may be of a less severe form, or the disease may not be present.
- Negative results can also occur in individuals with other autoimmune diseases.
Sample Type:
- The test typically requires a blood sample (serum) from the patient. A blood draw is performed, and the serum is analyzed for the presence of anti-Scl-70 antibodies.
