Overview

There are no diagnostic lab findings associated with orbital cellulitis. Some patients with orbital cellulitis may have elevated ESR, CRP, and white blood cells with a left shift. These are non-specific findings associated with infections, inflammatory conditions, and some neoplasia.

Laboratory Findings

There are no diagnostic lab findings associated with orbital cellulitis. Some patients with orbital cellulitis may have elevated ESR, CRP and white blood cells with a left shift. These are non-specific findings associated with infections, inflammatory conditions, and some neoplasia. Despite low positive and negative predictive values, blood and nasal mucosal cultures are often ordered to guide targeted antibiotic therapy but do not contribute to the diagnosis of orbital cellulitis.
