Determination of Complement Factor C3c Concentration

What is it?
It is one of the main tests for complement system proteins. The complement system is a complex part of the immune system that helps eliminate infectious microorganisms and supports the body's response to inflammation.

How is it performed?
The test is performed using venous blood. No specific preparation is required.

When is it recommended?

• Suspecting autoimmune diseases (e.g., systemic lupus erythematosus);
• Assessing the body's inflammatory response;
• Monitoring complement activity in infectious or chronic diseases.

Benefits:
Helps determine whether the complement system is functioning properly. A decreased C3c level may indicate an inflammatory process or an immune system disorder. The test is often performed together with C4.
