Complement Component C3c details
What Complement Component C3c shows
Complement C3 is one of the central proteins in your complement system, a group of proteins that work together as part of your immune system's defense against infection and help clear immune complexes from your blood. Low C3 can indicate that the complement system is being actively consumed — a pattern often seen during active flares of autoimmune conditions like lupus, or during certain infections and kidney conditions (glomerulonephritis). It's typically tested alongside C4 and sometimes total complement (CH50), since the specific pattern of C3 and C4 levels together can help point toward the underlying cause and, in known autoimmune conditions, help track disease activity over time.
Tests that include Complement Component C3c
Complement C3 is a protein in the immune system that plays a key role in the complement cascade, which helps fight infections and clear damaged cells. A C3 test measures its levels in the blood and is often used to evaluate immune function or inflammatory conditions. Low C3 levels may indicate autoimmune diseases like systemic lupus erythematosus (SLE) or complement system deficiencies, while elevated levels can be seen in acute or chronic inflammation.
- Complement Component C3c One of the main proteins in your complement system, part of your immune defense. Low levels can indicate active autoimmune disease or certain infections.

- Complement Component C3c One of the main proteins in your complement system, part of your immune defense. Low levels can indicate active autoimmune disease or certain infections.
Decreased concentrations of both C3 and C4 suggest activation of the classical pathway, whereas decreased concentration of just C3 suggests activation of the alternative pathway. Both complement factors may be used to monitor activity of patients with systemic lupus erythematosus (SLE) and immune complex-induced vasculitis.
- Complement Component C3c One of the main proteins in your complement system, part of your immune defense. Low levels can indicate active autoimmune disease or certain infections.
- Complement Component C4c A complement system protein involved in immune defense. Low levels are associated with active autoimmune conditions like lupus, or certain genetic deficiencies.
