WebThe CH50 assay will be abnormal if there are specific hereditary or acquired C1-C9 complement component deficiencies or if there is consumption of complement due to immune (or autoimmune) complexes. This assay is a screening test for complement abnormalities in the alternative pathway. WebNov 9, 2024 · The CH50 functional test measures the function of the complete classical complement pathway, mediated by components C1 – C9. If this measurement is outside the normal range, then each of the nine different complement levels can be measured individually to look for hereditary or acquired deficiencies.

WebEvaluation of total complement function in human serum is an essential component of laboratory diagnostics of the human complement system. During recent years, established hemolytic assays for classical pathway and alternative pathway function, CH50 and AP50 assays, respectively, have been replaced in many diagnostic laboratories by ELISA assays.
WebFollow-up test for complement activity screening when CH50 is low or absent and AH50 is normal and high suspicion remains for complement deficiency. Allow specimen to clot for one hour at room temperature. Separate serum from cells ASAP or within 2 hours of collection. Transfer 1 mL serum to an ARUP Standard Transport Tube and freeze …
WebFunctional hemolytic assay for total complement activity: CH50 and APH50. Because complement components are heat-labile, samples for complement assays should be handled with proper precautions.
