Your doctor may order a hs-CRP if they’re focusing on cardiovascular issues. While the regular C-reactive test can help uncover different diseases that cause inflammation by measuring high levels of protein, the hs-CRP test measures lower (but still elevated) levels of protein, which can signal the risk of heart disease and stroke.
This test typically predicts heart disease and stroke. It’s important to note that a high-sensitivity C-reactive protein (hs-CRP) test is a slightly different test than a regular C-reaction protein test. If you have a previously diagnosed inflammatory issue, your doctor may also order this test occasionally to see how your treatment is working, and if the issue is being properly managed. This test can show there’s a high level of inflammation, but it does not show where the inflammation is located or what might be causing it. 12 July 2009.If your doctor suspects you may have an inflammatory disorder (like arthritis, cancer, an infection, etc.), they may order a C-reaction protein test. American Association for Clinical Chemistry. “Inflammation, Heart Disease and Stroke: The Role of C-Reactive Protein.” American Heart Association.“C-Reactive Protein.” Lab Tests Online.The American Heart Association and Centers for Disease Control and prevention maintain that a high-sensitivity CRP of less than 1.0 mg/L suggests a low risk for CVD, 1.0-3.0 mg/L suggests an average risk, and a CRP above 3.0 mg/L suggests a high risk. The antiserum contains a specific substance that is able to detect the CRP. However, the HS CRP can reflect many things in lupus patients besides lupus activity and/or one’s risk of heart attack.įor the HS CRP test, blood is taken from a vein in your arm and mixed with a substance called an antiserum. The high sensitivity CRP is important because studies have shown that lupus patients have higher levels of atherosclerosis than the general population. A high sensitivity test (high sensitivity C-reactive protein, or HS CRP) is used to evaluate this risk, because the level of CRP in the blood is low. In apparently healthy individuals, studies have shown that C-reactive protein (CRP) can be an indicator of the risk of cardiovascular disease (CVD), since certain types of CVD, namely atherosclerosis, are known to involve inflammation. High Sensitivity C-Reactive Protein (HS CRP) An elevated CRP can also be seen after someone has a heart attack, surgical procedure, or infection.
It is important to realize, though, that a low CRP value does not necessarily mean that an individual is experiencing no inflammation a low CRP can be seen in lupus patients with active inflammation. However, the amount of CRP can give an idea as to the degree of inflammation your body is experiencing, and it is used by doctors in lupus treatment to monitor flares and to assess how well your medications are working. The CRP is non-specific, meaning it cannot give your doctor information about where inflammation is occurring in your body. CRP plays a part in your immune response by interacting with your body’s complement system. However, CRP usually changes more rapidly than ESR because it is made by the liver and secreted hours after the beginning of infection or inflammation. Like the erythrocyte sedimentation rate, the C-reactive protein (CRP) test measures inflammation.
