Identification of a condition, disease, disorder, or problem by systematic analysis of the background or history, examination of the signs or symptoms, evaluation of the research or test results, and investigation of the assumed or probable causes. Effective prognosis is not possible without effective diagnoses.

In Vitro Diagnostics

An in vitro diagnostic is a method of performing a diagnostic test outside of a living body in an artificial environment, usually a laboratory. Everyday examples of in vitro testing include checking blood for signs of infections, or urine for the presence of glucose. The expression ‘in vitro’ comes from Latin, literally meaning “within the glass”. The name reflects the fact that historically such tests were conducted in glass vessels, such as test tubes.

The concept of ‘in vitro’ contrasts with that of 'in vivo' – literally 'within the living' - where the tests are conducted within a whole, living organism. Examples of in vivo testing include the clinical testing of new pharmaceuticals in human volunteers. In addition, the recently adopted expression 'in silico' testing refers to carrying out experiments by means of a computer simulation.


Medical Imaging

Medical Imaging, or in vivo diagnostics, technologies that allow clinicians to see the human body for normal biologic processes or pathological indications. Imaging is a key part of medicine and most diagnoses in medicine occur after an imaging procedure. Technologies that are including in imaging are x-ray, magnetic resonance imaging ( MRI ), and ultrasound.

But newer technologies are the focus of the imaging industry and thus the subject of many market reports.
