what information does a PVC give you
measures level of packed red blood cells and can show anemia.
why do you prepare two hematocrit tubes instead of one
in case one of them leaks during the centrifuge process you still have one. And to balance the centrifuge
what must you do to the end of the hematocrit tube
put a plug with the Clay

used to measure total protein

How do you name decrease in ‘phils’ and ‘cytes’

What is a decrease in red blood cells known as ?
Anemia
What is an increAse in white blood cells mean
Leukocytosis
What does a decrease in white blood cells mean
Leukopenia
What is the disadvantage to using automated counter
Can get misleading information. Could give low red blood cell values if there is a lot of agglutination. Cannot count all the cells in the clump.
What do you use to stain a reticulocyte
Methylene blue
What are the inclusions on the reticulocyte
Rna
Why is counting the reticulocytes useful
Can indicate whether anemia is due to low erythropoiesis or hemolysis ( ie. Production problem vs destruction problem)
What is needed for an abnormality to be considered significant
Need to find it in every field of view examined
What are the types of abnormalities
Color Distribution SiZe - anisocytosis Shape - poikilocytosis Inclusions
What is hypochromasia
Large central pallor, decreased Hemoglobin, could be due to iron deficiency.
What are polychromatophils
Make up less than 1% of red blood cells in circulation. Larger in size, purpleish, still have nuclear material. Rare in the horses
What is agglutination
Clumping of a erythrocytes. Often due to an immune mediated disease. Caused by the cross-linking of antibodies. Cells held together firmly.
What is Rouleaux
Coins. Can be an indicator of some disease, some Rouleaux present in nonruminant’s especially cats and horses. Caused by weak electrostatic attraction’s on cell surface. Cells held together loosely. Saline agglutination test can help distinguish between them. High amounts of plasma proteins can increase rouleaux.
What are Heinz bodies
Normally found in cats. Less than 10% of red blood cells. Pathological finding in other species. Result of oxidative cell injury such as red Maple poisoning in horses.
How do you do a white blood cell differential
Count 100 white blood cells and keep track of each type seen
Describe the difference between dog red blood cells and cat and horse red blood cells
Dog red blood cells are larger and tend to have a more central Paller than cats and horses. Cat red blood cells appear more spherical than horses and dogs
Describe the difference between eosinophils and heterophils
Eosinophils are slightly larger than heterophils. The nucleus is less segmented and the cytoplasmic granules are larger, round and bright red compared to heterophils. Granules usually completely fill the cytoplasm.

What is minor crossmatching
Recipient rbc tested with donor plasma
Is the first transfusion of the wrong blood type usually a problem
Nope. It’s the ones after that
What is IMHA
