Cytologies should be submitted, stained and unstained, in plastic or cardboard slide holders. Biopsies should be submitted in an adequate amount of formalin. Small representative sections of necropsy tissue should be submitted with an effort to avoid redundant collection of specimens from any one tissue. Small birds may be submitted whole submerged in formalin, with the skull cap and sternum removed. Small turtles may be submitted whole with plastron removed. Other small animals (some lizards, amphibians, rodents, fish) may be submitted whole with the coelomic/abdominal cavity opened. Animals submitted whole in formalin are charged as multiple tissue cases (not necropsies).
