Intended Use

Immunoturbidometric assay for the in vitro quantitative determination of CRP in human serum and plasma on Roche automated clinical chemistry analyzers.

Device Story

Tina-Quant C-Reactive Protein Gen 3 is a particle-enhanced turbidimetric assay for quantitative CRP measurement in human serum and plasma. The device utilizes latex particles coated with monoclonal anti-CRP antibodies; human CRP in the sample causes agglutination of these particles. The resulting precipitate is measured turbidimetrically at 570 nm on Roche automated clinical chemistry analyzers. The assay is operated by laboratory technicians in clinical settings. Output is a quantitative CRP concentration (mg/L), which healthcare providers use to assess tissue injury. The device provides an automated, standardized method for CRP quantification, facilitating clinical decision-making regarding inflammatory states and tissue damage.

Clinical Evidence

Bench testing only. Precision studies demonstrated within-run CVs of 0.48-4.00% and between-run CVs of 1.9-6.2%. Analytical sensitivity reported as LoB 0.2 mg/L, LoD 0.3 mg/L, and functional sensitivity 0.6 mg/L. Method comparison against the predicate device on the Hitachi 917 analyzer showed a slope of 1.020, intercept of 0.000, and correlation coefficient (r) of 1.000. Interference testing confirmed no significant impact from hemolysis (up to 1000 mg/dL), lipemia (L index 1000), or icterus.

Technological Characteristics

Particle-enhanced turbidimetric assay. Reagents: latex particles coated with monoclonal anti-CRP antibodies. Detection: turbidimetric measurement at 570 nm. Platform: Roche/Hitachi automated clinical chemistry analyzers. Measuring range: 0.3-350 mg/L. Sample types: serum, Li-heparin plasma, K2/K3-EDTA plasma.
