Part Description

LP29040-0   Complement total hemolytic CH50
Complement total hemolytic CH50 testing is used to monitor Systemic Lupus Erythematosus (SLE) patients' response to therapy. It is also used to evaluate complement component deficiency, complement activity in patients with immune complexes , glomerulonephritis, rheumatoid arthritis, and cryoglobulinemia. Complement is a system of 25 proteins associated with cell membranes and present in plasma; it plays a vital role in the function of the immune system. Complement components function in the "classical" and "alternative" pathways. The CH50 assay mainly evaluates the classical pathway. Complement proteins are activated during the acute phase of inflammation or infection. Decreased levels of complement components occur during hypercatabolism, expenditure in immune complexes or due to hereditary deficiency. Decreasing complement levels may signal upcoming clinical problems, especially lupus nephritis. Source: Regenstrief Institute

Change Reason
Updated term to align with existing complement activity terms and clarify that findings are based on actual/normal results.; The EIA method, which was always intended to cover more than just enzyme-linked immunoassay and whose display name for the long common name has always been Immunoassay, was renamed IA in order to eliminate ambiguity about whether the method has a broader meaning than just enzyme-linked immunoassay. Likewise, EIA.rapid was renamed IA.rapid. These changes were approved by the Laboratory LOINC Committee in June 2016.
