The permanent stained smear is designed to facilitate the identification of intestinal protozoa.Several staining methods are available;the two most common methods are the Wheatley's modification of the Gomori tissue trichrome and the iron-hematoxylin stains.This part of the O&P examination is critical for the confirmation of suspicious objects observed in the wet examination and for the identification of protozoa that might not have been seen in the wet preparation.The permanent stained smear is the most important procedure performed for the identification of intestinal protozoan infections;the permanent stained smears are examined using oil immersion objectives (600× for screening,1000× for final review of 300 oil immersion fields).
