Common errors in parasite fecal diagnostics

In this dvm360® interview, Michael Dryden, DVM, MS, PhD, university distinguished professor of veterinary parasitology (emeritus) at Kansas State University, explained common problems with using passive floatation for parasite fecal diagnostics. He added, though, that practices are starting to move away from this method and implement better diagnostic technologies to detect these infections.

The following is a partial transcript of the video.

Michael Dryden, DVM, MS, PhD: For a number of decades now many practices have used what we call passive flotation...where you're just passively floating the eggs up through the flotation medium, and you let it sit on the counter for some period of time. And the data showed, actually very good data that the vast majority of practices, that's what they were doing...but the problem is it doesn't work very well.
