Opsonin activity (OA) was investigated in serum samples from cord blood of 11 full-term newborn infants and 12 healthy adult volunteers by the method of luminol-dependent chemiluminescence (L-CL) and Cypiridina luciferin analog-dependent chemiluminescence (CLA-CL) together with the measurement of complement components (C3, C4, C3A and properdin). CL and complement components of cord samples were significantly lower than that of healthy adult blood. CLA-CL showed a significant correlationship to C3 and C3A. L-CL also displayed a significant correlationship to C3A but the relationship to C3 was not significant. From these results, when OA is measured by CL, CLA-CL is preferred to L-CL as a technique.
