Patient : Hello,
My question is more in the field of immunology but I didn't find it in the list.
Today I got the results from the blood tests I did this week and C4 complement is 6.5 (lab normal: 15 - 53) and C3 is 117 (lab normal is 82 - 185). I am scared I may have Hereditary Angioedema (i had 4 episodes of angioedema in the past) or some immunological disease. Can the low C4 complement be harmless or it clearly sugests a disease?
