Fluorescence Immunoassay Analyzers quantify proteins, hormones and antibodies by reading the fluorescent signal from a labelled test cartridge, giving numeric results where lateral flow strips give only a line. Test menus span cardiac markers, thyroid and fertility hormones, tumour markers and infectious diseases including HIV, hepatitis, influenza and COVID-19. Whole blood, serum, plasma, urine or saliva samples run directly, with automatic calibration and quality control on each cartridge lot. Portable, handheld and table-top formats suit emergency rooms, clinics and remote sites. Typical users include hospitals, diagnostic centers, point-of-care clinics and veterinary practices.
