What is an Immunoassay?
An immunoassay is a biochemical test that measures the presence or concentration of a macromolecule or a small molecule in a solution through the use of an antibody or antigen. Common types include:
- ELISA (Enzyme-Linked Immunosorbent Assay)
- RIA (Radioimmunoassay)
- Chemiluminescent Immunoassays (CLIA)
- Lateral Flow Assays (used in rapid testing kits)
These methods are widely used in:
- Disease diagnostics (HIV, COVID-19, cancer biomarkers)
- Therapeutic drug monitoring
- Hormone level detection
- Food and environmental safety
Key Market Drivers
- Rise in Chronic and Infectious Diseases Increasing cases of cancer, cardiovascular conditions, and infections like HIV and COVID-19 are fueling the need for early, reliable diagnostics.
- Technological Advancements Innovations such as automated immunoassay analyzers, multiplex assays, and point-of-care testing devices are boosting market demand.
- Growing Elderly Population Aging demographics are more susceptible to chronic illnesses, increasing the need for diagnostic testing.
- Expansion in Point-of-Care Testing (POCT) Immunoassays are now widely used in POCT due to their simplicity, rapid turnaround, and portability.
