In general, diagnostic tests do not typically need to be performed for suspected blepharitis. Research and other rare protocols may involve eyelid margin cultures, transillumination studies of the meibomian glands, digital-imaging techniques, conjunctival impression cytology, marginal biopsies, or even analysis of gland secretions.

Testing patients with blepharitis for tear insufficiency or nasolacrimal drainage problems is appropriate because these can be associated with blepharitis and can often complicate management.
