78433-0Soluble liver IgG Ab [Presence] in Serum 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. Various manufacturers classify this method as an immunoblot technique. 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 is Line blot.

Part Description

LP71714-7   Soluble liver
The presence of SLA antibodies has almost 100% specificity for autoimmune hepatitis, although only 12-30% have these antibodies. Thus, a negative SLA IgG test does not rule out autoimmune hepatitis. Source: ARUP Laboratories, SLA

Change Reason
This term was created for an assay that uses a membrane strip pre-coated with a specific set of antigens in parallel lines. Because the antigens are seperated by electrophoresis/chromatographic separation during manufacturing, not during the test procedure itself, this test was assigned a LOINC Method of Immunoassay (IA) and not Immunoblot (IB). However, upon further review of IA, IB, and Immunoblot strip methodologies and regulatory distinctions between these, we changed the Method from IA to Line blot so that users can distinguish between these three Methods. The meaning of the term has not changed since it was created for an IB strip assay as described in the term description.
