This trend is improving the diagnostic process, contributing to better patient management and outcomes, thus propelling the growth of the market.

Radioimmunoassay (RIA) is a sensitive and specific laboratory technique used to measure concentrations of antigens (such as hormones, drugs, or proteins) in various biological samples through the use of radioactively labeled substances. RIAs are categorized into competitive and non-competitive assays.

In competitive assays, a known quantity of radioactive antigen competes with the non-radioactive antigen present in the sample to bind to a limited number of antibody sites. Non-competitive assays, also known as immunoradiometric assays (IRMAs), involve the use of two antibodies: one labeled with a radioactive isotope and other responsible for capturing the antigen.

The applications of RIA are vast, including hormone level monitoring (e.g., insulin, thyroxine), drug testing, allergy testing, and the detection of infectious diseases. It is extensively used in clinical diagnostics, pharmaceutical research, and biotechnological studies. End users of RIA technology include hospitals, diagnostic laboratories, research institutions, and pharmaceutical companies.

These entities heavily rely on the high sensitivity and specificity of RIA to conduct accurate diagnostic tests, develop new drugs, and carry out cutting-edge research, thereby contributing to advancements in healthcare and medical science.
