Detection of Intestinal Parasites
Algorithm Close-up

March 2009
Going back to our algorithm, you’ll see that Cryptosporidium antigen testing is recommended for patients with watery diarrhea and one of several risk factors. Some of these patient groups overlap with those at risk for Giardia infection, and in those instances, a physician may chose to order both Giarida and Cryptosporidium antigen tests. However, the tradition stool ova and parasite examination would not be indicated as a first line test for these patients.
