CDC DPDx Diagnostic Procedures Stool Specimens

May 03, 2016Stool specimens can be examined fresh or preserved. Examination of fresh specimens permits the observation of motile trophozoites, but this must be carried out without delay. Liquid (diarrheic) specimens (which are more likely to contain trophozoites) should be examined within 30 minutes of passage (not within 30 minutes of arrival in the laboratory!), and soft specimens (which

Fecal Flotation VCA Animal Hospital

Fecal flotation is a routine veterinary test used to diagnose internal parasites or worms. The test detects the eggs of mature parasites that live inside the body and pass their eggs to the outside by shedding them in the host's stool.

Flotation Technique for Fecal Parasite Concentration Methods

This technique is predominantly used in parasitology laboratories. By exploiting the density of the parasites, particularly eggs, it allows the parasites to float to the top of a dense solution (final specific gravity of about 1.20) and can then be skimmed from the top of the tube.. The most commonly used reagent is zinc sulphate.Operculated eggs as well as schistosoma and infertile Ascaris

DiagnosisPreventionPreparationUseResultsTo perform a fecal flotation, your veterinarian places a small amount of fecal material into a small container and mixes it with a special solution. This solution is made so that the eggs of many parasites (such as whipworms, hookworms, and roundworms) will float to the top. Your veterinarian then covers the top of the container with a microscope coverslip and allows it to sit for a few minutes. During this time, the parasite eggs float to the top of the solution and stick to the coverslip. After a few minutes, your veterin
