- 1. Quantitative measurement of serum complement C4.
2. Evaluation of complement system function.
3. Diagnosis and monitoring of autoimmune diseases.
4. Identification of complement deficiencies.
5. Monitoring response to treatment in complement-associated diseases.

Purpose: Serum complement C4 is a protein of the immune system. This quantitative analysis is performed to measure the levels of this protein in the blood serum and to evaluate the immune function and inflammatory response of the body.
Common indications: It is used in cases where there is suspicion of autoimmune disorders, kidney disease, chronic infections or as part of a follow-up to monitor the status of the immune system.
Sample collection: A blood sample is usually taken from the patient's arm by venipuncture. This sample is placed in a specific test tube for laboratory analysis.
Sample processing: In the laboratory, the blood sample is centrifuged to separate the serum (liquid part) from the red blood cells and other cellular components. An analysis is then performed to measure the concentration of Complement C4 in the serum.
Interpretation of results: The results show the levels of Complement C4 in the blood. Abnormal concentrations, whether high or low, may indicate conditions such as autoimmune disorders, kidney disease, chronic infections, or other immune-related problems.
Clinical use: Results are used as a complementary diagnostic tool to assess immune status and inflammatory activity. They help healthcare professionals confirm diagnoses, assess the severity of certain diseases, and monitor the immune system's response to specific treatments.
