The term "theranostic" is a portmanteau of two words, therapeutic and diagnostic, thus referring to a combination of diagnosis and treatment that also allows for continuing medical assessment of a patient. The first known use of the term is attributed to John Funkhouser, a consultant for the company Cardiovascular Diagnostic, who used it in a press release in August 1998.[6]
