What is normal range for C3?

Is C3 high or low?

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.

Lupus patients usually have low C3 and C4 levels during disease flares because of activation of the complement system by immune complexes (ICs) [1].

What if C3 and C4 are high?

High expressions of C3 and C4 are related to adipose tissue variables and involved in the development of visceral adiposity30. Therefore, the complement system response to inflammation and infection may play an important role in MetS expression.

What is considered a low C3 level?

Low C3 and C4 levels, below 60 for C3 and 15 for C4 (in the usual American measure), occur in active lupus, especially in the setting of kidney disease or immune breakdown of blood cells (autoimmune hemolytic anemia, AIHA). Some types of lupus, such as brain disease, do not cause low complement levels.

What causes elevated C3 and C4?

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].

Levels of C3, which tend to be well maintained in patients with SLE, probably because of effective regulation of classical pathway activation by C4 binding protein, may be substantially below the normal range in patients with anti-C1q autoantibodies [107].

What is a C3 and C4 blood test for?
