Symptoms of elevated C-Reactive Protein (CRP) levels include fever, fatigue, joint pain, and general discomfort. The CRP test is a medical tool used to assess inflammation in the body. Elevated CRP levels can indicate various underlying health issues, such as infections, autoimmune disorders, or cardiovascular disease. While this test doesn’t directly diagnose specific conditions, it helps healthcare professionals identify potential problems. Physicians use CRP results in conjunction with clinical evaluations to make informed decisions about further diagnostic tests and treatment plans for patients.
