What is the FR-CRP test?

Under normal circumstances, FR-CRP usually refers to C-reactive protein (CRP), which is a test item in blood biochemical examination. CRP can be used to assess the severity of bacterial infection and to evaluate the effectiveness of anti-infective treatment. The specific analysis is as follows:

C-reactive protein is a type of protein in plasma that rises rapidly when the body experiences infection or tissue damage. It plays a regulatory role by activating the complement system and enhancing phagocytosis by phagocytes, thereby helping to eliminate invading pathogens as well as damaged, necrotic, or apoptotic tissue cells. CRP exists in the blood or other bodily fluids and is an extremely sensitive indicator of bacterial infection.

If a patient experiences physical discomfort, infection, or injury, a blood test for C-reactive protein can help determine whether a viral infection is present. Elevated CRP levels suggest acute or chronic inflammatory diseases, non-specific infections, severe trauma, acute myocardial infarction, rheumatoid arthritis, or systemic vascular diseases; decreased CRP levels may indicate conditions such as hypoproteinemia or liver cirrhosis.

If a patient develops any symptoms of illness, it is recommended to seek timely medical evaluation at a hospital to avoid delays in diagnosis and treatment.
