c-reactive protein
Definition
Noun: A protein produced by the liver and found in blood plasma, whose levels rise significantly in response to inflammation, infection, or tissue injury. It is a key biomarker used in medicine to detect and monitor acute inflammatory conditions.
Usage
C-reactive protein is used as a specific medical term. It is most commonly discussed in clinical and laboratory contexts to assess a patient's health status. * It is typically measured via a blood test. * High levels indicate the presence of an acute inflammatory process in the body. * It is often abbreviated as CRP.
Examples
- The doctor ordered a test for C-reactive protein to check for possible infection.
- A high level of C-reactive protein is a nonspecific indicator of inflammation.
- Monitoring CRP levels helps assess the effectiveness of anti-inflammatory treatment.
Advanced Usage
- High-sensitivity C-reactive protein (hs-CRP): A more sensitive assay used to measure very low levels of CRP, which can indicate low-grade, chronic inflammation associated with cardiovascular disease risk.
- Example: The hs-CRP test is sometimes used to evaluate a person's risk for future heart attacks.
Variants and Related Words
- CRP: The standard abbreviation for C-reactive protein.
- Acute-phase protein: C-reactive protein is classified as an acute-phase protein, a group of proteins whose plasma concentrations increase or decrease in response to inflammation.
Synonyms
- Inflammatory marker: A broader term for any substance measured to assess inflammation, which includes CRP.
- Acute-phase reactant: A technical synonym emphasizing its role in the body's acute-phase response to injury or infection.
Notes
- C-reactive protein is named for its ability to react with the C-polysaccharide of .
- While elevated CRP signals inflammation, it does not diagnose the specific cause (e.g., whether it is due to infection, autoimmune disease, or injury). Further investigation is always required.
Noun
-
a byproduct of inflammation; a globulin that is found in the blood in some cases of acute inflammation
