A serological testing algorithm for the diagnosis of primary CMV infection in pregnant women

Serological diagnosis of CMV primary infection is usually based on the detection of specific IgM antibody. However, as the presence of IgM antibody is not always correlated with primary infection, measurement of IgG avidity must be performed. The aim of our study was to evaluate the best procedure for serological diagnosis of CMV primary infection. In other words, is it better to first search for IgM antibody, and, if positive, then measure IgG avidity, or first measure IgG avidity without the detection of IgM antibody?
