C4 Complement near me in New Delhi









Available at an affordable price in New Delhi with Tata 1mg labs, the C4 Complement, the C4 Complement test is a blood test that assesses levels of Complement Component 4 (C4), a protein involved in the immune system's complement cascade. This test is helpful in detecting autoimmune diseases, infections, and other conditions where there is dysfunction in the immune system.
The C4 Complement test is especially helpful in identifying and monitoring autoimmune disorders, where changes in C4 levels are indicative of disease flare-ups or remission phases. Doctors may also advise the C4 blood test to individuals who have unexplained symptoms of autoimmune or inflammatory conditions, such as joint pain, renal issues, skin rashes, recurrent infections, or if you have a family history of autoimmune diseases. It is also used to assess disease activity and effectiveness of treatment in patients with SLE or other conditions that involve complement system dysregulation.
Overnight fasting (8 to 12 hours) is preferred for this test, however not mandatory.








What does C4 Complement measure?
The C4 Complement test measures the complement protein C4 level in the blood, which is an important part of the immune system. C4 has an important role in the complement system that fights infections, triggers inflammation, and clears out damaged cells. By determining C4 levels in the blood, this test offers crucial insights into the activity and functionality of the complement system. Abnormal (lower or higher than healthy range) results may point toward autoimmune conditions, inflammatory diseases, or infections, helping doctors diagnose and monitor various health issues related to the immune system.
