Perchloric acid, toxicolor, endospecy, and miconazole in the early diagnosis and treatment of fungemia.

As a procedure for the diagnosis of fungemia, Toxicolor and Endospecy (limulus tests using a synthetic chromogenic substrate) were used to measure (1----3)-beta-D-glucan (beta-glucan), which is a membranous component of fungus. The plasma samples were pretreated with a new perchloric acid method. These methods permit measurement of the beta-glucan within about two hours. Patients in whom fungemia was diagnosed were effectively treated with miconazole.
