The result of my SS-A/Ro Antibody, IgG, Serum is 1.6 and it says High. What could this mean? I have many lupus symptoms.

Indeterminate. Anti-SSa/Ro autoantibodies are present in about 0.1-0.5 percent of people. There is an association with lupus but also biliary cirrhosis and Sjögren's syndrome. If you have this and other symptoms if lupus, as u say, it is possible you have lupus. You should consult with the doctor who ordered the blood work to determine for sure the next steps. Good luck!
