Area of Science:

  • Clinical chemistry
  • Biomedical instrumentation
  • Immunodiagnostics

Background:

  • Automated immunoassay testing is crucial for efficient clinical laboratory operations.
  • Existing methods may have limitations in speed, throughput, or analyte range.

Purpose of the Study:

  • To introduce and describe the IMx, a novel automated instrument for clinical immunoassay testing.
  • To highlight the technologies and capabilities of the IMx system.

Main Methods:

  • The IMx instrument utilizes Microparticle capture Enzyme ImmunoAssay (MEIA) for high-molecular-mass analytes and fluorescence polarization immunoassay (FPIA) for hapten assays.
  • It employs a front-surface fluorometer for MEIA and a fluorescence polarization optical system for FPIA.
  • Robotic automation with a carousel processes up to 24 patient specimens.
