Question

In order to successfully float parasitic eggs and other fecal debris, the specific gravity of the flotation solution should be maintained within what range?

1) 1.10-1.20
2) 1.20-1.30
3) 1.30-1.40
4) 1.40-1.50

Answer 1

The correct specific gravity range of a flotation solution for successful floatation of parasitic eggs and other fecal debris is 1.20-1.30. This range allows the less dense eggs to suspend in the solution, aiding in their detection under a microscope.

Step-by-step explanation:

The specific gravity of a flotation solution used to float parasitic eggs and other fecal debris in veterinary diagnostics should be within the range that allows the eggs and debris to suspend in the solution without sinking or floating to the surface. This specific gravity range is 1.20-1.30. Solutions within this range have a higher density than pure water (specific gravity of 1.0), which allows the less dense parasitic eggs to float. The precise control of specific gravity is crucial for the diagnostic accuracy of fecal flotation tests, as it ensures that the eggs are separated from the feces and can be detected and identified under a microscope.
