Final answer:
The blood sample showing dispersed cells upon adding saline indicates Rouleaux formation, which is reversible stacking of red blood cells.
Step-by-step explanation:
The finding that would be supported by a feline blood sample that exhibits stacked red blood cells observable with a microscope that, upon addition of saline, results in dispersed cells is a. Rouleaux formation. Rouleaux formation refers to the stacking of erythrocytes (red blood cells) and can be reversed with the addition of saline solution, which disperses the cells.
Agglutination occurs when antibodies bind to antigens on the surface of red blood cells, causing visible clumping. One notable assay for detecting such a reaction is the Coombs' test, which can indicate the presence of certain antibodies. Coagulation, on the other hand, is the process of blood clotting involving platelets, fibrinogen, and clotting factors to prevent bleeding.
