Presentation of Quiz #2

The Microbiology section has just decided to incorporate immunoassays for Giardia lamblia and Cryptosporidium parvum into the laboratory test menu. The laboratory is also considering the addition of tests for the Entamoeba histolytica/Entamoeba dispar group and the true pathogen, Entamoeba histolytica. What factors should be considered prior to implementation of these immunoassays? Please comment on the issues presented below.

It is important to remember that the immunoassay tests currently available are not designed to “take the place” of the Ova and Parasite examination (O&P) (direct wet smear [fresh specimen only], concentration, and permanent stained smear). Both the O&P examination and the immunoassays for intestinal protozoa should be separate orderable, billable tests.
