- Description and Primary Use
- The complement system is part of the inate immune system that quickly responds to destroy foreign pathogens. This test provides the qualitative determination of total classical complement activity in blood. Low levels of total hemolytic complement may occur during infections, disease exacerbation in patients with lupus erythematosus and in patients with immune complex diseases such as glomerulonephritis. Undetectable levels suggest the possibility of a complement component deficiency.
