सारांश	ELISA is a plate-based immunoassay technique that detects and quantifies proteins, antibodies, antigens, hormones, and other analytes in biological samples. Widely used in veterinary science, medicine, and food safety, it exploits the specificity of antibody–antigen binding coupled to an enzyme-driven colorimetric signal to deliver sensitive, reproducible measurements across large sample batches.	Flow cytometry is a laser-based technology for analyzing and sorting individual cells based on fluorescent markers. Developed by Leonard Herzenberg in the 1970s, flow cytometry enables rapid assessment of cell phenotype, drug effects on cell populations, and therapeutic cell characterization in immunology and hematology.	Radioimmunoassay (RIA) is a highly sensitive, quantitative laboratory technique that measures the concentration of a specific antigen — such as a hormone, drug, or pathogen-derived protein — in a biological sample by exploiting competitive binding between a radiolabelled antigen and the sample antigen for a limited supply of specific antibody. Developed in the late 1950s, RIA is widely used in veterinary science, endocrinology, pharmacology, and clinical diagnostics.
