Anti SCL-70 Antibody

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.

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

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

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.

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