Clinical Chemistry Analyzer
Clinical chemistry analyzers use measurement technologies including photometric and colorimetric testing, ion-selective potentiometry, and latex agglutination to analyze samples such as blood serum, plasma, and urine. Chemistry analyzers are used in all types of laboratories, from small point-of-care clinics to high-throughput clinical labs, to test for analytes such as proteins, enzymes, and electrolytes. Applications include monitoring diseases such as diabetes, testing for metabolic functions or cardiac markers, and drugs-of-abuse testing. Benchtop analyzers are the most common type, but compact bedside models, usually with fewer test options, and high-throughput floor-based units are also available.
These analyzers can be benchtop devices or placed on a cart; other systems require floor space. They are used to determine the concentration of certain metabolites, electrolytes, proteins, and/or drugs in samples of serum, plasma, urine, cerebrospinal fluid, and/or other body fluids. Samples are inserted in a slot or loaded onto a tray, and tests are programmed via a keypad or bar-code scanner. Reagents may be stored within the analyzer, and it may require a water supply to wash internal parts. Results are displayed on a screen, and typically there are ports to connect to a printer and/or computer.
