89533-4SCL-70 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

LP16758-2   SCL-70 extractable nuclear
Topoisomerase I (also known as Scl-70) is a nuclear enzyme that plays a role in releasing tension that is introduced in double-stranded DNA during DNA replication by transiently cleaving and rejoining one strand of the DNA duplex. Anti-Scl-70 autoantibodies are a marker of systemic sclerosis as well as other autoimmune diseases, including systemic lupus erythematosus (SLE). In patients with systemic sclerosis, anti-SCL-70 may be associated with more severe disease, and in patients with SLE, anti-SCL-70 suggests an increased risk of pulmonary hypertension and renal involvement. In general, anti-SCL-70 antibody status may help with diagnosis, treatment planning and prognosis in patients with connective tissue disease.
