Question

Quizplus · Accepted Answer

The osmotic fragility test measures the ability of erythrocytes to withstand swelling and shrinking in response to changes in the osmotic environment. This property is directly related to the surface-to-volume ratio of the cells, as cells with a larger surface-to-volume ratio tend to be more fragile in hypotonic solutions. Size and fragility of red cell organelles are not directly measured by this test.
