Fluorescent immunoassay (FIA) is another immunoassay technology commonly employed in autoimmune disease testing, offering enhanced sensitivity, dynamic range, and multiplexing capabilities compared to traditional colorimetric assays. FIA assays utilize fluorescently labeled antibodies, antigens, or detection probes to generate specific signals in response to target analytes in patient samples. Fluorescent signals are detected and quantified using fluorescence detection systems, such as fluorescence microplate readers or flow cytometers, enabling rapid, quantitative, and multiplexed analysis of multiple analytes in a single sample. FIA technology is particularly useful for detecting low-abundance biomarkers, analyzing complex sample matrices, and performing high-throughput screening in autoimmune disease research, biomarker discovery, and clinical diagnostics.

Chemiluminescence immunoassay (CLIA) represents another robust immunoassay technology widely utilized in autoimmune disease testing, offering high sensitivity, wide dynamic range, and excellent signal-to-noise ratios for detecting and quantifying specific antibodies, antigens, or biomarkers in patient samples. CLIA assays utilize chemiluminescent labels, such as acridinium esters or luminol derivatives, coupled with enzyme-catalyzed reactions to produce light emissions proportional to the concentration of target analytes. Chemiluminescent signals are detected and quantified using specialized luminometers or chemiluminescence immunoassay analyzers, enabling sensitive and quantitative measurement of analytes across a broad range of concentrations. CLIA technology is widely employed in clinical laboratories, diagnostic companies, and research institutions for autoimmune disease diagnosis, patient monitoring, and therapeutic monitoring applications.

Radioimmunoassay (RIA) is a classic immunoassay technology that utilizes radioactive isotopes, such as iodine-125 or tritium, coupled with antigen-antibody interactions to detect and quantify specific antigens or antibodies in patient samples. RIA assays offer high sensitivity, specificity, and precision for measuring low-abundance analytes, making them particularly useful for detecting trace levels of hormones, proteins, or antibodies in biological fluids. However, RIA technology has become less common in clinical practice due to safety concerns associated with radioactive materials, as well as advances in non-radioactive immunoassay technologies offering comparable sensitivity and specificity with improved safety profiles.
