C1r levels in sera from 100 normal adults were determined by electroimmunoassay. The 95 percent range was 71‐133 per cent of a normal reference pool. C1r values were well correlated to the levels of C1q (r = 0.708) and of C1s (r = 0.768). The interplate variation of the method on double determinations was 3.4 (SD). C1r values in normal sera not appreciably affected by storage at room temperature or by repeated freezing and thawing. The C1r antigen in EDTA plasma was found to be labile.
