IMTEC-SS-B/La-Antibodies is an indirect solid-phase enzyme immunoassay (ELISA) for quantitative and qualitative measurement of IgG class autoantibodies against SS-B in human serum. The assay is intended for in vitro diagnostic use only as an aid in the diagnosis of Sjögren’s syndrome.

Autoantibodies directed against SS-B/La are especially detected in patients with Sjögren's syndrome at a frequency of 70%. These antibodies are also detectable in patients with SLE (25%), NLE (up to 70%) and subacute cutaneous lupus erythematosus (80%). Anti-SS-B/La-antibodies often occur together with antibodies to SS-A/Ro.
