pepperbird Posted July 31, 2020 Posted July 31, 2020 a question re: antibody levels. When doing an antibody panel for autoimmune diseases, does a "positive" Sm antibody finding (paired with a positive ANA) always indicate lupus? Does the number matter, or just that's it's positive?
introverted1 Posted August 5, 2020 Posted August 5, 2020 ANA is not specific for lupus as it can be elevated in a number of conditions, many benign. Your doctor should be able to educate you on the tests that are specific for lupus.
