Packed Cell Volume (PCV)
Packed Cell Volume (PCV)
A test that measures the percentage of red blood cells in a blood sample. It's like checking the ratio of red cells to the total blood volume.
Red Blood Cells
Red Blood Cells
Tiny, disc-shaped cells responsible for carrying oxygen throughout the body. They contain a protein called hemoglobin, which binds to oxygen.

Study Notes
Blood Sample Analysis
- Packed Cell Volume (PCV) measures the percentage of red blood cells in blood.
- Red blood cells transport oxygen throughout the body, utilizing the protein hemoglobin.
- Normal PCV range for dogs is between 40% and 59%.
- Red blood cells are also known as erythrocytes.
- White blood cells are referred to as leukocytes, playing a crucial role in immune defense.
- Plasma is the liquid component of blood, essential for transportation of nutrients and waste.
- Polycythemia may result in symptoms like diarrhea in affected animals.
- White blood cells defend against pathogens such as bacteria, viruses, and fungi.
- The lifespan of an average red blood cell is approximately 100 days.
Blood Draw Techniques
- The caudal tail vein is the preferred site for obtaining small blood samples from cattle.
- The medial saphenous vein can be used for blood collection from cats, but not from dogs.
- Platelets are produced in the bone marrow, contributing to clot formation.
- Lymphocytes, a type of white blood cell, are not formed in bone marrow; they develop in lymphoid tissue.
- The jugular vein is the optimal location for collecting large blood samples from horses.
- Following an injury, platelet levels increase, facilitating blood clotting and healing.
