Corneal Epithelial Scraping (Identification of Acanthamoeba)

Acanthamoeba keratitis may mimic herpes simplex keratitis. The prevalence of this infection may be greater than suspected previously

Our laboratory developed a rapid screen for the identification of Acanthamoeba organisms in corneal epithelial scrapings.

Our lab staff can answer questions for you about the proper techniques required for this rapid screening test.

 

Acanthamoeba trophozoite nested between two benign corneal epithelial cells. The specimen was obtained from a corneal epithelial scraping. Hematoxylin-eosin stain.
