Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry"), the ...
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 .
Serum protein electrophoresis (SPEP or SPE) is a laboratory test that examines specific proteins in the blood called globulins. [1] The most common indications for a serum protein electrophoresis test are to diagnose or monitor multiple myeloma , a monoclonal gammopathy of uncertain significance (MGUS), or further investigate a discrepancy ...
A blood test is a laboratory analysis performed on a blood sample that is usually extracted from a vein in the arm using a hypodermic needle, or via fingerprick. Multiple tests for specific blood components, such as a glucose test or a cholesterol test , are often grouped together into one test panel called a blood panel or blood work .
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]
Consequently, if an ANA test is positive, it is often followed up with other tests associated with arthritis and inflammation, such as a rheumatoid factor (RF), an erythrocyte sedimentation rate (ESR), a c-reactive protein (CRP), and/or complement protein|complement levels.

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]
