1the mean C3 and C4 levels of the CIC-positive patients. C3 and C4 levels fell within the normal range for all CIC-positive patients (C3 normal range: 910–1500 mg/L; C4 normal range: 140–435 mg/L). C3 and C4 levels were not determined in CIC-negative patients. Four of 61 apparently normal individuals were CIC-positive
