What Does CIEIA Stand For?

CIEIA stands for Competitive Inhibition Enzyme Immunoassay

CIEIA, or Competitive Inhibition Enzyme Immunoassay, is a diagnostic technique used to measure the concentration of specific antigens or antibodies in a sample. This method involves the competition between a labeled analyte and an unlabeled target molecule for binding to a specific antibody. The resulting signal produced by the enzymatic reaction correlates inversely with the concentration of the target molecule, allowing for accurate quantification. CIEIA is widely utilized in biochemical research and clinical diagnostics due to its sensitivity and specificity.
