The c4 protein is lower than normal in the body when there’s an active inflammation in the body. For patients with an active diagnosis of inflammatory autoimmune conditions, this test can be used to test the efficacy of offered treatments. Based on the test results, doctors can determine whether the treatments are effective or not by measuring whether the c4 protein levels are increasing or not. If the protein levels are increasing it could indicate positive efficacy of treatment and decreasing protein levels could indicate the opposite.
