What are the similarities between ELISA and CLIA (chemiluminescence)?

ELISA and CLIA are two types of immunoassay techniques that rely on the binding of antibodies to specific antigens to detect and quantify target proteins or other biomolecules in a sample. 

Both techniques are highly specific and sensitive, making them effective for detecting low concentrations of target analytes. Both are versatile techniques that can be used for a wide range of applications in various clinical and research settings
