CRP and temporal arteritis: The diagnosis of GCA is typically made using the American College of Rheumatology criteria, which involves clinical systemic symptoms, a positive TAB, and elevated erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and potentially elevated platelet counts.[3] However, it is important to keep in mind that this disease can present itself in a wide spectrum, and a high index of suspicion is required to reduce the potential of missing this critical disease.
