In vitro diagnostics refers to a wide range of medical and veterinary laboratory tests that are used to diagnose diseases and monitor the clinical status of patients using samples of blood, cells, or other tissues obtained from a patient.
Molecular diagnostics uses in vitro biological assays such as PCR-ELISA or Fluorescence in situ hybridization. [19] [20] The assay detects a molecule, often in low concentrations, that is a marker of disease or risk in a sample taken from a patient.
Laboratory-developed tests (LDTs) are a class of in vitro diagnostics (IVDs) designed, manufactured, and used within a single laboratory. They are employed for various medical diagnoses and research applications, offering advantages in flexibility and fostering innovation in the diagnostics field. [2]
The European Union defines that a rapid test means qualitative or semi-quantitative in vitro-diagnostic medical devices, used singly or in a small series, which involve non-automated procedures and have been designed to give a fast result. [3]
In vitro diagnostics, a category of medical tests; Ideographic Variation Database, a database of Unicode's ideographic variation sequences
A Strategic Group of Experts on In Vitro Diagnostics (SAGE IVD) is appointed by the WHO to advise on its development as it is regularly reviewed and expanded. [8] Different countries can adapt it; the Indian Council of Medical Research produced its own version of the EDL in 2019, a year after the first edition. [9]
Often a portion of the definition of a medical device is intended to differentiate between medical devices and drugs, as the regulatory requirements of the two are different. Definitions also often recognize In vitro diagnostics as a subclass of medical devices and establish accessories as medical devices. [citation needed]
A bioassay is an analytical method to determine the potency or effect of a substance by its effect on living animals or plants (in vivo), or on living cells or tissues (in vitro). [1] [2] A bioassay can be either quantal or quantitative, direct or indirect. [3] If the measured response is binary, the assay is quantal; if not, it is quantitative ...
