ICI

ICI, or Immunochromatographic Assay, is a quick diagnostic test that detects specific substances, like proteins or pathogens, in a sample such as blood or saliva. It works by using antibodies that bind to the target substance, producing a visual change—often a colored line—on a test strip. Commonly used for rapid testing in medical settings, such as pregnancy tests or infectious disease screening, ICIs are valued for their simplicity, speed, and ease of use, providing results within minutes without the need for complex laboratory equipment.
