89531-8Smith extractable nuclear Ab [Presence] in Cerebral spinal fluid by Line blotActive

Term Description

This term was created for, but is not limited in use to, the submitter's test strip, a membrane strip pre-coated with a specific set of antigens in parallel lines. If antibodies to any of those antigens are present in the patient's serum, they will bind to the specific antigen. The bound patient antibodies are then detected using labelled anti-human antibodies. Manufacturers call this method by different names, including immunoblot, line blot, and line immunoassay. LOINC uses the immunoblot (IB) method to mean that some electrophoretic/chromatographic separation occurs such that position (size) of the band is part of the assessment (as in Western blot). Because this assay does not involve a separation step but rather uses strips with pre-fixed antigens, the LOINC Method for this term is Line blot.

Part Description

LP39757-7   Smith extractable nuclear Ab
The presence of Smith antibody is specific for systemic lupus erythematosus (SLE), but occurs only in 30-35% of patients with SLE. The Smith and related nuclear ribonucleoproteins are targets for the autoantibodies developed by patients with SLE.
