Test Information

Observation of coccidia is routinely part of the Fecal Float test. Low numbers of Cryptosporidium/Giardia may not be detected with this technique.

Cryptosporidium/Giardia, if suspected, should be ordered separately (see Cryptosporidium and Giardia Antigen)

Normal Result is Negative

Interpretation
Fecal flotation is used to detect the majority of helminth ova which occur in animal feces.  Most nematode and protozoal ova will be detected by the flotation method.  Fecal sedimentation permits recovery of most trematode (fluke) ova and embryonated ova which are too dense to float.  The Baermann sedimentation method is used to detect larvae in feces.  
Flotation method: Zinc sulfate (specific gravity: 1.181)
