QIA

QIA stands for Quantitative Immunoassay, a laboratory technique used to measure the amount of a specific substance, such as a protein or hormone, in a sample. It works by using antibodies that specifically bind to the target substance. When the antibody binds, a detectable signal, often a color change or fluorescence, is produced proportionally to the amount of the substance present. This method allows precise, accurate quantification, making it useful in medical diagnostics, research, and quality control to assess the levels of specific molecules in biological samples.
