What effect does hemoconcentration have on blood test results?

Hemoconcentration refers to the increased concentration of cells and proteins in the blood due to a reduction in plasma volume. This can occur in situations such as dehydration or when samples are taken after prolonged lack of fluid intake. The correct answer accurately states that hemoconcentration can falsely elevate values for various parameters in blood tests.

This occurs because, as the plasma volume decreases, the relative proportion of solid components, such as red blood cells and proteins, increases. Consequently, tests that measure these components will yield higher concentrations. For instance, the concentration of electrolytes, proteins, and some hormones may all appear elevated due to this process.

This phenomenon is significant for veterinary clinical pathology as it may lead to misdiagnosis or incorrect assessment of the animal's health status if hemoconcentration is not considered. Understanding the implications of hemoconcentration helps veterinary professionals interpret blood test results accurately and makes them aware of the need for proper sample handling and collection protocols to prevent such situations.
