LOINC display name : Cryptosporidium sp IF Ql (Water);
LOINC long common name : Cryptosporidium sp [Presence] in Water by Immunofluorescence;
LOINC short name : Cryptosp Wat Ql IF;
LOINC description : Cryptosporidium oocysts and cysts are identified in water through immunofluorescence,
where they are characterized by size, shape, and fluorescence and then counted. The
US Environmental Protection Agency has published guidelines for processing a water
sample for testing (https://www.epa.gov/sites/production/files/2015-07/documents/epa-1623.pdf).
This process starts with filtering a water sample to remove solids, then elutes the
material and centrifuges the elute to pellet the oocysts and cysts. These are then
removed from other materials in the sample and stained with fluorescent antibodies
for analysis.;
