C-Reactive Protein (CRP) is a blood test that measures the level of CRP, a protein produced by the liver in response to inflammation. It's a nonspecific marker of inflammation, meaning it can be elevated in various conditions, including infections, autoimmune diseases, and heart disease. While CRP doesn't diagnose a specific condition, it can help monitor disease activity, assess the risk of heart attack or stroke, and guide treatment decisions.

A Complete Blood Count (CBC) is a comprehensive blood test that provides information about the cells in your blood. It measures the number of red blood cells, white blood cells, and platelets, as well as hemoglobin (the protein that carries oxygen) and hematocrit (the percentage of red blood cells in your blood). A CBC is used to diagnose and monitor a wide range of conditions, including anemia, infections, bleeding disorders, and blood cancers.
