C-Reactive Protein (CRP), Quantitative
C-reactive protein (CRP) is one of the most sensitive of the acute-phase reactants. Measurement of CRP is useful for the detection and evaluation of infection, tissue injury, inflammatory disorders, and associated diseases.
Immune complexes formed in solution scatter light in proportion to their size, shape, and concentration. Turbidimeters measure the reduction of incidence light due to reflection, absorption, or scatter.
Collect: Serum Separator Tube (SST) - 0.5 ml serum
Specimen preparation: Serum free from hemolysis is the recommended specimens. Allow blood samples to clot (15 mins). Separate the serum from the cells by centrifuging for 10 minutes. Store serum at 2-8°C until analysis.
Stability: CRP specimens are stable for 11 days when stored at 18 - 25°C (room temperature) and 2 months when stored 2 - 8 °C. For longer storage, freeze serum at <-20°C.
