Complement C4 Test

Are you experiencing recurrent infections, joint pain, or kidney problems? A Complement C4 Test may help uncover the cause. This simple blood test measures your C4 protein levels, which play a key role in your body’s immune response and inflammation control. Abnormal C4 levels can point to autoimmune diseases, immune system disorders, or kidney issues. Identifying these changes early allows your healthcare provider to recommend targeted treatment and manage symptoms effectively. Taking a C4 blood test is an important step in evaluating your immune health, preventing potential complications, and supporting your overall well-being.
