Hematocrit, or packed cell volume (PCV), is the percentage of red blood cells in the blood and is crucial for assessing overall health. Normal levels vary by age and gender, and measurement methods include centrifugation and automated analyzers. This tool is essential for diagnosing conditions like anemia, monitoring blood loss, and evaluating hydration status.

Applications
Understanding Packed Cell Volume
and Its Medical Relevance

2. What is Hematocrit (PCV)?
• - Hematocrit, also called Packed Cell Volume
(PCV), is the percentage of red blood cells in
the blood.
• - It is measured using a centrifuge or
automated machines.
• - Helps assess the overall health and detect
various conditions.

3. Normal Hematocrit Levels
• - Men: 40-54%
• - Women: 36-48%
• - Children: 35-49%
• - Newborns: 55-68%
• Note: Values may vary slightly based on
laboratory standards.

4. Methods of Measuring PCV
• - Centrifugation Method:
• - Blood sample is spun in a centrifuge to
separate components.
• - Packed red cell layer is measured.
• - Automated Analyzers:
• - Advanced machines calculate PCV indirectly
based on red blood cell count.

5. Applications of Hematocrit (PCV)
• - Diagnosis of anemia and polycythemia.
• - Monitoring blood loss and fluid balance.
• - Assessing response to treatments like blood
transfusions.
• - Evaluating dehydration or overhydration.

6. Conclusion
• - Hematocrit (PCV) is a vital diagnostic tool.
• - It provides insights into red blood cell health
and overall blood composition.
• - Essential for detecting and managing various
medical conditions.
