Theranostics is a term used to describe the proposed process of diagnostic therapy for individual patients. This involves testing for possible reaction to a new medication and tailoring a treatment based on the test results.

It encompasses the utilization of a wide range of subjects including predictive medicine, personalized medicine, integrated medicine and pharmacodiagnostics. The method is looked upon as the possible end result of new advances made in new drug discovery, molecular biology and microarray chips technology.

Although the use of the term Theranostics has been criticized as less than accurate, it is in line with today’s personalized approach to medicine, especially as it relates to cancer treatment. The stakes have never been higher to know that a drug therapy is working in real time than with cancer. Tumor responsiveness is critical to successful treatment and the term used to describe the process of making clinical treatment decisions mid-therapy in direct response to that precise therapy is Theranostics.

However, Theranostics is a confusing term and not understood by most professionals. There is no difficulty in describing this concept without using a special term, so if one needs to use a single word to describe a test linked to therapy, one can use pharmacodiagnostics, which is more appropriate and easy to understand.
