Test Information
​Fecal Egg Count if Performed if Fecal Float is Positive
Reference Intervals
Performing Location Reference Intervals
​All Sites ​Float: Normal result is Negative

Egg Count:
Normal result is Negative
Positive value is resulted numerically.
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)
