RIA: The Foundation of Radioimmunology
RIA is a powerful analytical method used to detect tiny quantities of biological substances such as hormones, drugs, and antigens.
How RIA Works:
A radioactive tracer and a non-radioactive version of the target molecule compete to bind to a specific antibody.
Measuring the radioactivity in the bound fraction determines the substance’s concentration in the sample.
Advantages of RIA:
✅ Exceptional Sensitivity: Capable of detecting substances at extremely low concentrations, essential in fields like endocrinology and pharmacokinetics.
✅ High Specificity: Delivers accurate results with minimal interference.
✅ Proven Reliability: Decades of successful application in clinical and research settings.
While concerns about radiation safety and waste management have encouraged the adoption of methods like ELISA and chemiluminescent assays, RIA remains indispensable where the highest sensitivity is required.
