Detection of Intestinal Parasites
Cryptosporidium - Cysts with Acid Fast Stain
March 2009
This is special stain that we offer for Cryptosporidium detection in feces, which stains the oocysts a deep red-purple color as shown on this slide. You can see that they stand out very nicely against the blue-green background. However, this is also a subjective examination and low levels of infection may not be detected, again, arguing for the use of the antigen test as the preferred method of detection.
