Description

Product Overview

The SAA / CRP Combo Test Kit enables simultaneous measurement of two important acute‑phase inflammatory biomarkers. SAA increases rapidly during early infection and tissue injury, while CRP reflects systemic inflammatory response. Combined evaluation improves clinical differentiation of bacterial and viral infections and helps monitor treatment response.

Intended Use

For in vitro quantitative determination of Serum Amyloid A (SAA) and C‑Reactive Protein (CRP) in human blood samples as an aid in diagnosis and monitoring of infection, inflammation and tissue injury.

Clinical Significance

SAA is an early acute‑phase protein that rises significantly during infection, trauma and inflammatory diseases. CRP is widely used for assessment of systemic inflammation, sepsis risk stratification and cardiovascular inflammatory conditions. Combined testing improves sensitivity and clinical confidence in emergency and ICU settings.

Test Principle

The assay is based on sandwich fluorescence immunoassay technology. Specific monoclonal antibodies labelled with fluorescent markers bind target analytes forming immune complexes. The fluorescence signal intensity measured by the analyzer is directly proportional to the concentration of SAA and CRP present in the sample.
