When evaluating RBC indicies you must know terminology. A normal MCHC is called ❌ while a normal MCV is ❌. Decreased MCV would be considered ❌ and an increase would be ❌. If the MCHC was low it would be considered ❌, and the high result would be ❌.

Only counting the aggregate reticulocytes during a reticulocyte count is standard procedure in dogs and cats.

Why would TP using serum yield lower test results?

A refractometer is used to conduct a TP test.

( Neutrophils, Basophils, Eosinophils, Monocytes ) are the most abundant WBC in most mammals and are known as ( Heterophils, Barr Bodies, Exoticophils, Hypersegmented Neutrophlis ) in avian, reptiles, fish, rats, rabbits, and guinea pigs. With the exception of bovine, who show ( Lymphocytes, Mycoplasma, Monocytes, Basophils ) as their most abundant WBC.

Normal TP ranges for serum are ❌ and plasma is ❌.

Platelet Count can be found by first scanning ( 10, 5, 50, 100 ) fields to find the average number/hpf. The normal range is between ( 8-10, 0-3, 1-5, 10-12 ) platelets/hpf. After the average is determined you multiply by ( 20,000, 20, 200, 2,000 ). If your results are less than 100,000 /uL your patient may have ( thrombocytopenia, hypopenia, platelet mass deficiency, vWD ).

Platelets, vWf, and vessel walls are essential in hemostasis, which produces platelet adhesion, activation, and aggregation.

1

During hemostasis fibrinogen converts to fibrin and strengthens the clot.

1

During tertiary hemostasis aids to break down the clot.

There are two types of analyzer types, Flow cytometry, which uses ❌ technology, such as the IDEXX Lasercyte in lab class; and Impedance, which uses a ❌ to process results, such as the Heska.
