title: Use of C6- and C7-deficient human sera in quantitative hemolytic assays for C6 and C7.
abstract: Quantitative hemolytic assays for C6 and C7 using as R reagents sera from patients deficient in these components are described. The assays gave linear results. Normal range for serum C6 was found to be 21,400--41,700 C6 hemolytic units/ml; for serum C7 the normal range was 5540--9860 C7 hemolytic units/ml.
