Flotation Technique for Fecal Parasite Concentration

Home Parasitology Flotation Technique for Fecal Parasite Concentration Methods Flotation Technique for Fecal Parasite Concentration Methods. 5 years ago by Medical Labs 0. 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

03/05/2016· Stool 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

pertonic effects exerted by the flotation solu-tion. The methods most frequently used to recover parasite eggs and oocysts are flotation techniques that rely on the differences in the specific gravity (SG) of the egg(s), fecal debris, and flotation solution. The SG of most parasite eggs is between 1.05 and 1.23.1 For parasite eggs to float, the SG of the flotation solution must be greater than

Because these modifications failed to improve oocyst detection, we developed a new stool concentration technique that includes FEA sedimentation followed by layering and flotation over hypertonic sodium chloride solution to separate parasites from stool debris. Compared with the standard FEA procedure, this technique improved Cryptosporidium oocyst detection. The sensitivities of the two
