Can anyone help me with an explanation?

I was diagnosed with microscopic poyangiitis in 2007. Recent test results included Anti-Scl75Ab+. I have not seen this before and do not understand it. Can anyone help me with an explanation?

Thank you

Does this help at all?

The introduction explains what they are and why they are looked at. As I understand it, they are very specific for certain types of scleroderma/myositis. Have you got symptoms that might relate to that?

Not that I am aware of but I don't know enough about that.

Than you.

It is a test that can be used to check for lung and muscle involvement in autoimmune diseases. A positive result may indicate pulmonary hypertension too so they should be testing for your blood pressure to check if you need medication or if you need meds adjusted. A positive would indicate they need to do more tests to explore.
