People are currently confronting major global healthcare difficulties as a result of emerging and reemerging diseases. Molecular diagnostics research has given us a greater understanding of molecular processes affecting human health and disease, and the tools developed as a result of this research are becoming the standard of care for the treatment of a variety of disorders. The technologies that fuel molecular diagnostics are constantly advancing to help solve some of the obstacles that come with using them, such as increasing their clinical utility. The fast-emerging technologies that underpin molecular diagnostics are poised to improve - perhaps even revolutionize - medical diagnosis and treatment.
