Complement factors C3 & C4
Complement Factor C3 is Important for the body’s immune function and response to inflammation. The main function is to destroy bacteria and viruses. C3 Levels are also used to identify low levels of immune function as well as the identification of autoimmune disease like Lupus, chronic inflammation, diabetes, metabolic syndrome, fatty liver, and CVD.
Complement Factor C4 is Important for the body’s immune function and response to inflammation originating from the HLA system. The main function is as a marker to connect the recognition pathways of the antibody antigen complexes to the effector proteins of the innate immune response system to mark and destroy pathogens, immune complexes and dying cells. Levels are used to determine SLE (Lupus), inflammation and risks of inflammatory nature including metabolic syndrome and CVD.
