At Creative Biolabs, total complement activity tests are respectively carried out by CH50 for the complement classical pathway, AH50 for the complement alternative pathway, and LP50 for the complement lectin pathway. Among the tests, CH50 and AH50 assays are based on the complement hemolytic activity detection while the LP50 is based on the enzyme immunoassay of the terminal complement complex detection. All test procedures are shown as follows, both a one-stop test for all three pathways and a test for any one pathway based on the client’s demands are all available.
