What does it mean when C3 complement is high?
The normal range for a complement C3 blood test is 80 to 160 milligrams per deciliter (mg/dL), or 0.8 to 1.6 grams per liter (g/L). Your complement levels will often rise very high just after an infection or injury. When your complement system responds to ongoing disease such as lupus, levels usually go down.
What is C3 complement blood test?
C3. Complement C3 is a blood test that measures the activity of a certain protein. This protein is part of the complement system. The complement system is a group of nearly 60 proteins that are in blood plasma or on the surface of some cells.
What disease can cause a high complement level?
If your results show higher than normal amounts or increased activity of complement proteins, it may mean you have one of the following conditions: Certain types of cancer, such as leukemia or non-Hodgkin lymphoma. Ulcerative colitis, a condition in which the lining of the large intestine and rectum become inflamed.
What causes low complement C3?
Decreased C3 may be associated with acute glomerulonephritis, membranoproliferative glomerulonephritis, immune complex disease, active systemic lupus erythematosus, septic shock, and end-stage liver disease.
What is a normal C3 level?
The normal range is 88 to 201 milligrams per deciliter (mg/dL) (0.88 to 2.01 g/L). Note: Normal value ranges may vary slightly among different laboratories. Talk to your provider about the meaning of your specific test results.
Why would C reactive protein be high?
A high level of CRP in the blood is a marker of inflammation. It can be caused by a wide variety of conditions, from infection to cancer. High CRP levels can also indicate that there’s inflammation in the arteries of the heart, which can mean a higher risk of heart attack.
What does elevated C3 and C4 mean?
It seems that elevated C3 and C4 are likely to result of increased synthesis in the liver in response to cytokines e.g. IL-1β, IL-6 or tumor necrosis factor (TNF), which are increased in active CU and are known to control synthesis of the APR proteins [9].
What is a normal complement C3 level?
What is the function of C3?
The C3 protein is essential for turning on (activating) the complement system. The presence of foreign invaders triggers the C3 protein to be cut (cleaved) into two smaller pieces. One of these pieces, called C3b, interacts with several other proteins on the surface of cells to trigger the complement system’s response.
What is C3 deficiency?
Disease definition. Complement component 3 deficiency is a rare, genetic, primary immunodeficiency characterized by susceptibility to infection (mainly by gram negative bacteria) due to extremely low C3 plasma levels.

Does high C-reactive protein mean Covid 19?
So, higher levels of CRP indicate more severe disease course‐linked to lung injury and worse prognosis. CRP levels are correlated well with the severity of symptoms of patients with COVID‐19; therefore, it may be a suitable marker in assessing a patient’s conditions together with other clinical findings.
