What does a test result for c3 low and c4 normal? c3 value is 11.69
A doctor has provided 1 answer
Autoimmune disease: The complement system is a group of proteins that move freely through your bloodstream. The proteins work with your immune system and play a role in the development of inflammation. C3 deficiency is characterized by recurrent bacterial infections, and different forms of kidney disease (glomerulonephritis). You can inherit a deficiency in your complement C3, but it's much more common to acquire it.
