✔ immunoassay analyzer is a laboratory instrument used to detect and measure specific substances in a sample, typically using an antibody as a reagent
✔ key features;  1.Antigen-antibody reaction: Immunoassay analyzers exploit the highly specific binding between antigens (the substances being measured) and antibodies
✔  2Detection methods: Various detection methods are used, including: Enzyme-linked immunosorbent assay (ELISA): Uses an enzyme-linked antibody to produce a measurable signal
✔  Chemiluminescent immunoassay: Uses a chemical reaction to produce light, which is measured.
