A member asked:
What illness could explain elevated c3 and c4 complement serum levels in the presence of angioedema? ana and rheum arth factor both negative.
A doctor has provided 1 answer
See details: Elevated levels mean nothing. The test were done to see in the C4 level was low and therefore would suggest hereditary angioedema..
