zinc sulfate flotation techniqu

Just Ask the Expert What fecal analysis method do you use?

Centrifugal fecal flotation using Sheather's sugar solution is considered the gold standard method for detecting most if not all veterinary helminth eggs and coccidial oocysts 1 2 and is the most suitable test for routine screening Fecal flotation works on the principle that most parasite eggs (and some larvae) have a specific gravity of about 105 to 120 3 so they are less dense than
