Total hemolytic activity (CH 50), C 3, and C 4 are frequently decreased in a variety of conditions producing immune complexes. By stabilizing C4b2a, it prolongs the half-life of this convertase and protects C4b2a against decay dissociation by C4 binding protein (C4BP). Complement activation split products are present only in trace amounts in normal plasma in vivo. The proteins work with your immune system and play a role to protect the body from infections, and to remove dead cells . C3 and C4 concentrations are often low in patients with active SLE.

If a patient has a blood clot or other signs of APS, anticoagulation (blood thinning) may be necessary, potentially life-long. Total complement activity (CH50, CH100) looks at the overall activity of the complement system. The complement system is a group of nearly 60 proteins that are in blood plasma or on the surface of some cells. Your complement levels will often shoot up dramatically just after an infection or injury. Furthermore, it is a crucial factor in connecting the recognition pathways of the overall system instigated by antibody .
