Answer

Conjunctival scrapings can be performed with topical anesthetic and gentle use of a platinum spatula or similar blunt metallic object. This should precede antibiotic therapy. Gram stain is useful to identify bacterial characteristics. Giemsa stain is helpful to screen for intracellular inclusion bodies of Chlamydia.
