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

LP220407-3   Titin
The titin protein plays a role in the assembly and functioning of striated muscles by connecting individual microfilaments, and may play a role in chromosome condensation and segregation during mitosis in non-muscle cells. [UniProt: Q8WZ42] Myasthenia gravis (MG) is an autoimmune disease mediated by antibodies against the acetylcholine receptor (AChR) in the postsynaptic membrane of the motor end plate, but antibodies against other targets, including titin, also play an important role. Anti-titin autoantibodies are also a sensitive marker for thymoma, which is often associated with MG, especially in patients with MG who are younger than 60 years old.

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.
