Screening for Giardia/Cryptosporidium Infections Using an Enzyme Immunoassay in a Centralized Regional Microbiology Laboratory
|
Context.-Stool parasitologic testing for Giardia and Cryptosporidium (G/C) previously relied on staining (ie, modified iron hematoxylin-kinyoun), ethyl acetate concentration procedures, and microscopy (the stool ova and parasite method). In April 1999, a microplate enzyme immunoassay (EIA) (ProSpecT G/C, Remel, Inc, Lenexa, Kan) for routine screening of all stool specimens was implemented.
Objective.-To determine the clinical and laboratory impact of this service change.
