What condition is characterized by a high red blood cell count, and what lab test is conducted to assess it?

Polycythemia Vera is a condition characterized by an increase in the number of red blood cells in the bloodstream. This overproduction can lead to increased blood viscosity, which can result in complications such as thrombosis.

To assess for Polycythemia Vera, a Complete Blood Count (CBC) is conducted. This test measures various components of the blood, including red blood cell count, hemoglobin levels, and hematocrit, which are critical in diagnosing this condition. A CBC provides an overview of the blood's cellular components and helps healthcare providers identify abnormalities that may indicate Polycythemia Vera.

The inclusion of CBC as the lab test highlights its role in monitoring overall health and diagnosing conditions involving red blood cells, making it the appropriate choice in this scenario.
