What is packed cell volume (PCV)?
Does your pet have a packed cell volume hematocrit?
The most common test to diagnose anemia is the packed cell volume (PCV), also called the hematocrit (HCT). In a normal dog, 35% to 55% of the blood will be red blood cells. If the PCV is below 35%, the dog is generally considered anemic.
- Albumin is a small protein produced by the liver. Albumin acts as a sponge to hold water in the blood vessels. When blood albumin is decreased, the pressure created by the heart forcing blood through the blood vessels causes fluid to leak out of the blood vessels and accumulate in body cavities or in tissues as edema.
- Alkaline phosphatase originates from many tissues in the body. When alkaline phosphatase is increased in the bloodstream of a dog, the most common causes are liver disease, bone disease, or increased blood cortisol from specific drugs or because the animal has Cushing’s disease (hyperadrenocorticism).
- ALT is an enzyme produced by liver cells. Liver damage causes ALT to increase in the bloodstream.
- Amylase is an enzyme produced by the pancreas and the intestinal tract that helps the body break down sugars. Amylase may be increased in the blood in animals with inflammation (pancreatitis) or cancer of the pancreas.
Jan 17, 2018 · In a normal dog or cat, the PCV is 35-50%. But Wait, There’s More to a PCV Than Red Blood Cells. The remainder of the volume in the capillary tube is a few percentages of white blood cells and platelets in a section called the buffy coat. A bit more than half of the tube is plasma, or the liquid component of blood.
Abnormally low PCV (anemia) may be caused by loss of blood (hemorrhage), breakdown of RBCs in circulation (hemolysis), or lack of production of RBCs by the bone marrow (hypoplasia or aplasia). Presentation varies according to whether the condition is acute or chronic.
Advantages: small volume of blood required, quick to perform. Automatic counters calculate the hematocrit from the cumulative volume of the cells counted. Standardize technique using microhematocrit method.
An additional CBC indicated that the spun packed cell volume (PCV) was elevated at 76%; plasma protein was within reference range at 6.7 g/dL. A moderate reticulocytosis of 393 370/µL was present.
Anemia is a condition of decreased oxygen carriage capacity that may be caused by an absolute decrease in red blood cell (RBC) numbers, hemoglobin concentrations, or packed cell volume (PCV). Normal reference values may vary based on species, breed, sex, reproductive status, age, and geographic location.
