What is Packed Cell Volume? Your Complete Guide

The percentage of your blood volume that is made up of red blood cells. It moves in tandem with hemoglobin — if one is abnormal, the other usually is too.

💡Simply Explained

Think of your blood as a smoothie — PCV tells you what percentage is the thick part (red blood cells) versus the liquid part (plasma). It moves hand-in-hand with hemoglobin.

📏Normal Range

🩺When to See a Doctor

High Packed Cell Volume

PCV above 55% may indicate thick blood — see a doctor within a few days, especially if you have headaches or blurred vision.

Low Packed Cell Volume

Very low PCV (below 25%) needs urgent medical attention. Moderate drops should be evaluated within 1-2 weeks.

🎯Did You Know?

About 45% of your blood is cells and 55% is plasma (the liquid part). That balance is what PCV measures!
