Segments of In Vitro Diagnostics (IVD)

Point-of-care testing (POCT) are the medical tests that are performed by trained healthcare professionals at or near the site of patient. Main POCTs include blood and urine tests. POCT is aimed to collect specimen and get accurate results in a very short span of time. POCTs are mainly used in primary care, secondary care and community care based settings. POCT are performed via portable instruments such as blood glucose meter, blood gas, pH, electrolyte and metabolite and haemoglobin measurement meters.

A companion diagnostic is a medical device/ diagnostic test/ imaging tool, used companion to drugs and provides information regarding the applicability of drug or biologics to a specific person. It helps the healthcare professionals to determine whether the product will be beneficial to the patients or will have any risks or side effects.

Molecular Diagnostics is a collection of various techniques that are used to analyse biological markers in the proteome and genome and how their cells expressed the genes by the application of molecular biology to genetic testing. Globally the use of Molecular diagnostics growing rapidly. Major clinical applications are in the areas of oncology, infectious disease, genetic diseases, pharmacogenomics, human leukocyte antigen typing; and coagulation.

Last five decades has seen a tremendous growth in Immunodiagnostics tests and it emerged as a potential diagnostic technique.  The radioimmunoassay and Enzyme Linked Immunosorbent Assay (ELISA) were the predominant techniques during the initial era of Imunodiagnostics.
