C4 Test (C4 Complement) and its Function
The C4 test, also known as the C4 complement test, is a laboratory test used to measure the levels of C4 complement component in the blood. The complement system is a part of the immune system that helps in the defense against infections and the clearance of immune complexes from the body. The C4 complement component is one of the proteins involved in the complement cascade, which is a series of reactions that help in the immune response.
Conditions that may require C4 Test (C4 Complement)
- Suspected Complement Deficiencies: Certain medical conditions, such as hereditary angioedema and systemic lupus erythematosus (SLE), are associated with deficiencies or dysfunctions in complement components, including C4. The C4 test can help in the diagnosis and monitoring of these conditions.
- Monitoring Disease Activity: In autoimmune diseases like SLE, the C4 test may be used to monitor disease activity and response to treatment. Decreased C4 levels can indicate disease flare-ups, while increased levels may suggest improvement.
- Evaluation of Kidney Disorders: Some kidney diseases, such as systemic lupus nephritis, can involve complement system activation and C4 consumption. The C4 test may be used to assess complement system involvement in these conditions.
