Blood tests are a common method used to detect inflammation in the body. There are several types of blood tests that can be used to diagnose inflammation, including a complete blood count (CBC), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and rheumatoid factor (RF).
The CBC test measures the number of red and white blood cells in the body, as well as the size and shape of the red blood cells. An abnormally high or low number of cells can be an indication of inflammation. Additionally, the presence of immature or abnormally shaped red blood cells can be a sign of inflammation.
The ESR test measures the rate at which red blood cells settle to the bottom of a tube when placed in a centrifuge. An elevated ESR can indicate inflammation in the body, especially if it is accompanied by other abnormal blood tests.
The CRP test is used to measure the amount of a protein in the blood called C-reactive protein. This protein is produced by the liver in response to inflammation. An elevated level of CRP can be an indication of inflammation in the body.
Finally, the RF test measures the presence of a protein called rheumatoid factor in the blood. This protein is produced by the immune system in response to inflammation and is often seen in people with rheumatoid arthritis. An elevated level of rheumatoid factor can be an indication of inflammation in the body.
Overall, a variety of blood tests can be used to detect inflammation in the body. A complete blood count, erythrocyte sedimentation rate, C-reactive protein, and rheumatoid factor can all be used to diagnose inflammation.
