Analyzers, Laboratory, Immunoassay, Photometric, ELISA

Definition : Photometric immunoassay analyzers that use enzyme-labeled antigens or antibodies and a solid-phase binding support (e.g., beads, microtiter plates) to detect and/or quantitate the substance of interest. These analyzers combine reagent and sample dispensers, washers, and photometric readers in a single instrument. Antigen detection may be performed using several methods, including competitive binding, "sandwich" technique, and antibody inhibition. ELISA (enzyme-linked immunosorbent assays) can detect nano- and picogram quantities of analytes. These analyzers are used mostly to evaluate the quantity of antigen or antibodies associated with most infectious viral diseases (e.g., measles, herpes, rubella) and other nonviral applications (e.g., mycoplasma pneumoniae), as well as many parasitic and fungal infections.
