Since the elevated level of guanidinosuccinic acid was demonstrated in sera of uremic patient by Bonas et al.(1963), so many studies have been focused on analyses of gua-nidino compounds as uremic toxins. In this monograph, more than 50 of naturally occurring guanidino compounds were classified, and analytical methods for guanidino compounds were reviewed compactly as follows:
