Following centrifugation, the RBCs are separated from the plasma. Plasma is mostly comprised of water, proteins, glucose, clotting factors, and mineral ions. When evaluating the PCV, the first step is to decide if the value is normal. While polycythemia a disease state where the proportion of blood volume that is occupied by red blood cells increases is possible, most commonly, an increase in PCV is seen with dehydration commonly termed hemoconcentration.

A more common clinical problem — at least in the veterinary ER or ICU — is the dilemna of determining why the patient is anemic e.

The TP is measured by breaking the hematocrit tubes once the PCV is determined following centrifugation, and placing the plasma directly onto the refractometer. The refractometer is then assessed pointing it into the direction of light — check out the picture to see the reading. The TP is the number read directly from the visible scale in this picture, a total protein of approximately 1. Next, the color and clarify of the plasma should be assessed.

If the plasma has a yellow-tinge, it typically represents an increase in bilirubin level. If the plasma has a red-wine color, the sample is typically hemolyzed e. Lastly, the serum should be evaluated for the presence of hyperlipidemia e. Similar to the PCV, the TP may vary slightly based on age and species, with normal values ranging from 6.

Elevated TP is most commonly seen with dehydration, with less common causes being chronic inflammation, neoplasia, infectious disease e. A lower than normal protein level can be seen with hemorrhage, malabsorption, liver disease e. April 25, at pm. April 26, at pm. Jordan says:. May 20, at pm. Mike Simons says:.

This number can also increase due to dehydration. Performing the PCV tests and the total solids is a pretty routine and simple test undertaken at many hospitals.

All medical members can easily perform the test but interpreting them is the tricky part. The readings can provide a lot of information regarding the patient's status and also help plan the next treatment step. A lower number of the PCV means that the RBC count loss is due to reasons such as blood loss, cell destruction and less bone marrow production. By looking at the tube out of the centrifuge, you can get an idea of the WBC content as well.

This buffy coat normally lies between the plasma and red cell layer. This shouldn't be counted as a part of the PCV test. There isn't any special preparation required for the PCV test. Also, any medications that you've been taking have to be relayed to the doctor. If there are any medical problems which are underlying too, you need to fast before taking a test.

A low PCV implies that the patient has a low number of red blood cells and is suffering from anaemia. The doctor may ask the patient to undergo further tests to determine the underlying causes of anaemia. Treatment will be given accordingly. The PCV test is calculated with the help of an automated analyser which means that it isn't directly measured.
