Anti SCL-70 Antibody

What is the Scl-70 Antibody test?

The Scl-70 Antibody test detects antibodies against the Scl-70 antigen, which is associated with systemic sclerosis, a type of autoimmune disease that affects the skin and internal organs.


Why is this test performed?

It is used to diagnose systemic sclerosis (scleroderma) and differentiate it from other autoimmune conditions like lupus or rheumatoid arthritis.


How is the test conducted?

A blood sample is collected, and the presence of Scl-70 antibodies is detected using immunoassay techniques such as ELISA or indirect immunofluorescence.


What do the test results indicate?

A positive result suggests systemic sclerosis, particularly the diffuse cutaneous form, which has a higher risk of internal organ involvement. A negative result does not completely rule out the disease.


What are the next steps after a positive result?

A positive result requires further clinical evaluation, imaging tests, and monitoring. Treatment focuses on managing symptoms with medications such as immunosuppressants and physical therapy.
