What is the CRP assay used for?

What is CRP?

C – reactive protein (CRP) is an acute phase protein found in blood plasma and produced by the liver. The concentration levels of CRP increase in response to cytokines which are produced by white blood cells during inflammation, infection and tissue injury.

What is the CRP assay used for?

Increased C-reactive protein concentrations occur much earlier compared to other acute phase reactants. It can be detected in the bloodstream within 4 to 6 hours. For more information on acute phase reactants, please click here [external link]. However, with tissue damage, the concentration levels of C-reactive protein in the blood can double every 6 hours. This rapid response to trauma or infection is the distinguishing feature of CRP. In addition, CRP levels return to normal quickly at the end of an acute episode making CRP useful for both the detection of acute episodes and the monitoring of treatment.

A complete clinical history is required for the accurate interpretation of CRP levels. CRP levels within the normal range may be affected by a number of different factors and should always be compared to previous values.

The Randox CRP assay is used for the quantitative in vitro determination of CRP concentrations in serum. The Randox CRP assay can be used to aid in the detection of:

  • Viral infections
  • Bacterial infections, including those in neonates
  • Infectious diseases
  • Tissue injury
  • Inflammatory conditions
  • Myocardial infarction
  • Monitoring recovery from surgery, particularly renal transplant patients
