What term describes the integration of chemistry and immunoassay in modern analyzers?

• A. Modular Analyzers
• B. Spectrophotometers
• C. Chromatography Systems
• D. Immunoassay Analyzers

Answer: (A)

The concept being tested is how modern analyzers combine different testing modes on a single platform. This integration is achieved with modular analyzers, which are built from interchangeable modules that handle different types of tests. A chemistry module runs standard biochemical assays using photometry or other detection methods, while an immunoassay module handles antibody-antigen tests with methods like chemiluminescence or colorimetric detection. Because the modules can be added, swapped, or upgraded, the same instrument can perform both chemistry and immunoassay tests, offering a unified workflow, automated sample handling, and higher throughput. This modular architecture is what makes the term a good description for combining chemistry and immunoassay capabilities on modern analyzers. In contrast, spectrophotometers focus on measuring light absorbance, chromatography systems specialize in separation, and immunoassay analyzers may focus on immunoassays but don’t by themselves describe the integrated, expandable platform.
