In vitro diagnostics are tests conducted to determine infections, diseases or conditions. These tests are performed in laboratory, at professional health settings or are used by consumers at home. In-vitro diagnostics medical devices are accessories used for the examination of specimens derived from the human body to deliver information for diagnostics, monitoring or compatibility purposes. This would help to prevent disease, help to detect infection, monitor drug therapies and diagnose a medical condition. These tests could either be used alone or in combination. The devices used, vary from simple tests to sophisticated DNA technology that includes reagents, kits, calibrators, software, control materials and other instruments. Clinical chemistry, urine test strips, HIV tests or hepatitis, coagulation test systems, diabetic blood sugar monitoring systems, pregnancy tests, are few examples of in-vitro diagnostic medical devices. These could be used by doctors as well as by individuals at home.
