Avian Hematology

Name five or more things that are part of an avian CBC

How many parts of the avian CBC can be obtained from one microhematocrit tube (MHCT)?

4-5 parts

What is the main difference between the total protein values in a bird and those in a mammal?

Mammal cut off it 3.5 cut off and avian 2.5

When doing a manual white blood cell count in birds (not a differential) what two cells are stained on the hemocytometer and counted?

Eosinophil, heterophils

When calculating a manual white blood cell count in birds, what two values do you need?

White bloods cells, leukocyte estimate factor

What is the formula for WBC count in birds?

Total WBC = number of cells stained in chamber x 32 x100
