^aDetermined as described for SeroHSV IgM in Materials and Methods. 

^bNo addition of free antigen. 

^cAddition of free HSV-1 plus HSV-2 antigens at a concentration 10 times higher than that of the bound antigen. 

^dAddition of free M. pneumoniae antigen at a 10-fold-higher concentration relative to the bound antigen.
