When a person experiences symptoms such as pain, redness, and swelling, it can indicate that their body is experiencing inflammation. To determine the cause of this inflammation and the extent of the damage, a doctor may order a blood test to measure certain biomarkers. Blood tests that measure inflammation can provide insight into a variety of conditions, including infections, autoimmune disorders, and chronic diseases like cardiovascular disease, diabetes, and cancer.
The most common blood tests to measure inflammation are the erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP). The ESR measures the speed at which red blood cells sediment in a tube of blood and is used to detect inflammation caused by infections, autoimmune disorders, and some cancers. The CRP is a protein produced by the liver and is used to detect inflammation caused by infection, injury, or chronic diseases.
In addition to the ESR and CRP, other blood tests that can be used to measure inflammation include: white blood cell count, which measures the number of white blood cells in the blood; ferritin, which measures the amount of iron in the blood; and albumin, which measures the amount of the protein albumin in the blood. These tests can help determine the cause and extent of inflammation and can be used to monitor the effectiveness of treatments.
Blood tests are an important tool in diagnosing and managing many inflammatory conditions. The results of these tests can provide insight into the cause of inflammation and can help guide treatment decisions. It is important to discuss the results of any blood tests with a doctor or other healthcare provider to ensure that the most appropriate treatment plan is put into place.
