Comparison of chemiluminescence and absorptiometry in enzyme immunoassays for protein quantification

The use of chemiluminescence in competitive binding assays for human serum albumin, human alpha-fetoprotein and human immunoglobulin G and in double antibody sandwich enzyme immunoassays for cytomegalovirus and herpes simplex virus increased the sensitivity of the detection of antigen or antibody 16- to 95-fold above that obtained by conventional absorptiometric methods.
