The packed cell volume illustrated in a blood sample provided is an indication of which condition?

Packed cell volume (PCV), also known as hematocrit, measures the proportion of blood volume that is occupied by red blood cells. A low packed cell volume indicates a deficiency in red blood cells, which is characteristic of anemia. Anemia can result from several underlying causes, including nutritional deficiencies (like iron or vitamin B12), chronic disease, or bone marrow problems.

In veterinary practice, assessing PCV is essential as it provides immediate insight into the animal's overall health and can guide further diagnostic steps. For instance, if the infectious disease or inflammation is present, it may not necessarily affect the PCV in a noticeably detrimental way initially, while severe dehydration may also result in an elevated PCV instead of a decrease.

Thus, a low PCV is a strong indicator of anemia, which aligns with the question's context. Understanding the implications of PCV is vital in diagnosing and managing conditions that affect red blood cell production or lifespan.
