C-reactive protein (CRP) is a substance produced by the liver in response to inflammation. It is commonly measured in blood tests to assess the level of inflammation in the body. High levels of CRP can indicate various health issues, including infections and chronic diseases, making it an important marker for doctors to track health conditions.
CRP matters for health because it helps in diagnosing and monitoring diseases. Elevated CRP levels can signal inflammation related to conditions such as rheumatoid arthritis, lupus, and even cardiovascular diseases. By understanding CRP levels, healthcare providers can better evaluate a patient's health status and make informed decisions about further testing or treatment.
In the body, CRP functions as part of the immune response. When there is inflammation, CRP levels rise, signaling the immune system to react. This response helps the body fight infections and heal injuries. However, chronic high levels of CRP may indicate ongoing inflammation that could lead to more serious health issues.
It is important to note that CRP is a non-specific marker, meaning it does not point to a specific disease. Instead, it indicates that there is inflammation somewhere in the body. Further tests are often needed to identify the exact cause of increased CRP levels.
