CH50 Total Complement

The CH50 Total Complement test, available at IntroLab in Belgrade, is a specialized assessment of the complement system, a crucial part of your immune system. This test offers important insights into your health by evaluating how effectively your body responds to infections and inflammation.

What is CH50 Total Complement?

CH50, or total hemolytic complement activity, is a test that evaluates the overall functionality of the complement system in the body.

The complement system consists of a group of proteins present in the blood that play a crucial role in the immune response to infections. These proteins work together to help the body combat bacteria, viruses, and other foreign substances. The complement system also supports the inflammatory response and aids in the removal of damaged cells.

The CH50 test measures the efficiency of the complement system in performing hemolysis—the destruction or lysis of foreign cells. This is done in a laboratory setting by adding sensitive red blood cells to the patient’s serum. If the complement proteins in the serum are present and functional, they will cause the red blood cells to lyse. The degree of hemolysis is then used to assess the functionality of the complement system.

Why is it performed, and who should be tested?

The CH50 Total Complement test is performed when there is a suspicion that the complement system is impaired or not functioning properly. These abnormalities can result from hereditary conditions, autoimmune diseases such as systemic lupus erythematosus (SLE) or rheumatoid arthritis, or infections. The test can help confirm the diagnosis of these conditions, monitor their progression, or assess the effectiveness of treatment.

How are the results interpreted?

Results are generally categorized as normal, elevated, or decreased. A normal result indicates that the complement system is functioning properly. Elevated results may indicate an acute phase of infection or inflammation, while decreased results may suggest an active autoimmune disease or a hereditary complement deficiency.

Specifics and subtypes of the test

The CH50 Total Complement test is a comprehensive assessment that evaluates the overall functionality of the complement system. Additionally, there are specific tests, such as C3 and C4, that assess the functionality of particular components of this system. Your doctor will decide which test is most appropriate for you, based on your symptoms and medical history.
