Weakly positive anti-Ro52 antibody alone is not clinically specific and only indicates autoimmune disorders and possible rheumatic immune system diseases such as dry syndrome. Anti-Ro52 antibody has certain reference value for diagnosing rheumatic immune system diseases, and its positivity is usually seen in dry syndrome, systemic lupus erythematosus, systemic sclerosis and other rheumatic immune system diseases. If the combination of anti-SSA and anti-SSB antibodies is positive and accompanied by symptoms such as dry mouth and dry throat, it may be dry syndrome; if the combination of anti-phospholipid antibody and anti-ds-DNA antibody is positive and erythema occurs, it may be systemic lupus erythematosus; if the combination of anti-nuclear antibody is positive, Raynaud’s phenomenon occurs and the skin becomes thicker and harder, it may be systemic sclerosis. Weakly positive anti-Ro52 antibody alone is not clinically specific, and generally needs to be analyzed in combination with clinical symptoms and other auxiliary tests. If you find anti-Ro52 antibody weak positive, it is recommended to go to the hospital in time, under the guidance of the physician, after a clear diagnosis to give targeted treatment.
