C-reactive protein (CRP) is an annular (ring-shaped) pentameric protein found in blood plasma, whose circulating concentrations rise in response to inflammation. It is an acute-phase protein of hepatic origin that increases following interleukin-6 secretion by macrophages and T cells .
Measurement of acute-phase proteins, especially C-reactive protein, is a useful marker of inflammation in both medical and veterinary clinical pathology. It correlates with the erythrocyte sedimentation rate (ESR), however not always directly.
The Dietary Inflammatory Index (DII) is a numerical score that assesses a diet for its effect on several biomarkers linked to inflammation. Its theoretical bounds are −8.87 to +7.98, and it is oriented such that negative scores are more anti-inflammatory and more positive scores are pro-inflammatory .
Ridker and his team found that in addition to LDL cholesterol, two other markers — a type of fat in the blood called lipoprotein (a), or Lp(a), and an indicator of inflammation — are important ...
In medicine, a biomarker is a measurable indicator of the severity or presence of some disease state. It may be defined as a "cellular, biochemical or molecular alteration in cells, tissues or fluids that can be measured and evaluated to indicate normal biological processes, pathogenic processes, or pharmacological responses to a therapeutic intervention."
Another test that checks the level of C-reactive protein (CRP) in the blood may also be conducted. CRP is produced by the liver in response to an injury or infection, and people with polymyalgia rheumatica usually have high levels. [17] [18] However, like the ESR, this test is also not very specific. [citation needed]
Reference ranges for blood tests, sorted logarithmically by mass above the scale and by molarity below. ( A separate printable image is available for mass and molarity ) Hormones predominate at the left part of the scale, shown with a red at ng/L or pmol/L, being in very low concentration.
C-reactive protein (CRP) is an acute phase protein. Therefore, it is a better marker for acute phase reaction than ESR. While ESR and CRP generally together correlate with the degree of inflammation, this is not always the case and results may be discordant [9] in 12.5% of the cases. [7]
