C-reactive protein: What is the PCR test and what is it for?

Expert answer:

The test that measures the C-reactive protein (CRP) dosage is done by collecting donor blood. C-reactive protein, produced in the liver, is the major acute-phase marker of inflammatory and necrotic processes (tissue death) that occur in the body, mainly inflammatory processes associated with bacterial infections.

Therefore, the PCR test is used to investigate the individual's inflammatory state and to assess the risk of cardiovascular disease.

It is a precise, fast, safe and economical method, but it is also a non-specific method, that is, it is not sufficient to diagnose any disease.

This is because CRP may be elevated in the blood due to any inflammation in the body. The condition that led to this inflammation (rheumatologic diseases, autoimmune, among others) should be further investigated by the physician with other tests.

Already to evaluate the risk of cardiovascular disease is done the examination of Ultra-sensitive PCR, which makes a more accurate dosing of C-reactive protein. Many cardiovascular diseases result from two factors:

  • Constant inflammation in the walls of blood vessels;
  • Cholesterol accumulation in these vessels.

People with CRP levels persistently above 0.3 mg / dL (3 mg / L) are at higher risk of developing cardiovascular diseases, such as stroke and stroke. With these values, the CRP indicates that there is a discrete but continuous inflammatory process.
