SS-B/La - Serological hallmark of Sjogrens syndrome, but a small proportion of patients remain SS-B/La negative. Reported in 6 to 15% of sera from SLE patients, SS-B/La antibodies are associated with a lower prevalence of dsDNA antibodies and renal disease in these patients. Although a strong association of neonatal lupus erythematosus (NLE) with anti SS-A/Ro was recognized first, the majority of mothers with babies with NLE are now known to have serum SS-B/La antibodies as well.

Testing was performed on the Phadia 250 analyzer using Fluorescence Enzyme Immunoassay technology.
