Giant cell arteritis typically presents with which laboratory finding?

Giant cell arteritis triggers a strong inflammatory response, so inflammatory markers rise markedly. The erythrocyte sedimentation rate is typically very high, often well over 100 mm/hr, and C-reactive protein is commonly elevated as well. This pattern is a hallmark of the condition and helps differentiate it from other causes of headaches or visual symptoms in older adults. Temporal artery biopsy positivity is diagnostic, but it isn’t a presenting laboratory finding and can be negative if skip lesions are present. Anemia can occur with chronic inflammation, but it’s not as specific or pronounced as the ESR elevation. White blood cell counts are usually normal or only mildly elevated. Therefore, the very high ESR best reflects the typical lab finding associated with giant cell arteritis.
