Progress in the development of microtechnology and its use in portable devices have made it possible for laboratory testing to move closer to the patient. The in-patient test, called POCT (Point of care testing), also known as in-bed analysis, was introduced in order to get the result of a blood sample analysis faster than you would get it from a laboratory. A rapid laboratory test is therefore defined as an analysis performed outside the laboratory, usually in the vicinity of the person or right next to him/her, and the test result may lead to changes in the patient's health care.
