flotation method of stool examination

Fecal Flotation Procedures - Jorgensen Laboratories

2017-5-2  Flotation solution must have a higher specific gravity than parasite egg or oocysts. ♦ Specific gravity refers to weight of object compared to equal volume of water. ♦ Specific gravity of water is 1.000 and most parasite eggs are 1.05 - 1.24 ♦ Flotation solutions should be > 1.24 Specific Gravity of Common Parasite Eggs - dogs and cats
