Good searching UKguy82!
I’ve got an autoimmune condition (Ankylosing Spondylitis, not cause by finasteride) so know a little about these tests. The Antinuclear antibody (ANA) test is usually used to diagnose Lupus although there are other autoimmune conditions which show a positive ANA (sarcoidosis, etc). I’m not sure there is a strong link to our symptoms really so not sure if the ANA test the most useful for us.
Although, I could be proved wrong. Has there been anyone on here who has developed autoimmunity from finasteride?
