3-Hydroxy-3-Methylglutaryl-coenzyme A reductase Ab [Presence] in Serum by Line blot
Active
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
LP220363-8 3-Hydroxy-3-Methylglutaryl-coenzyme A reductase Ab
3-Hydroxy-3-Methylglutaryl-coenzyme A reductase (HMG-CoA reductase or HMGCR) is an enzyme in the cholesterol-synthesis pathway and is the target of HMG-CoA reductase inhibitors, also known as statins. Autoantibodies to HMGCR may be a marker of necrotizing autoimmune myopathy (NAM), which is characterized by muscle fiber necrosis with little or no inflammation and responsiveness to immunosuppressive treatment. Anti-HMGCR positive cases of NAM usually have limited extramuscular involvement, slow onset of muscle disease, and can occur in both adults and children. Due to the insidious onset, pediatric cases of NAM may be initially confused with muscular dystrophy. The anti-HMGCR antibody titer may correlate with muscle strength and creatine kinase level. Some cases of NAM have been diagnosed in patients previously exposed to statins, and in some of these cases, stopping the statin drug was the only intervention necessary for the resolution of disease. However, exposure to statins is not required to diagnose cases of NAM, and first-line treatment typically includes corticosteroids or other immunosuppressive drugs such as methotrexate.

- 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.
