What does a Hematocrit test measure?

A Hematocrit test measures the percentage of blood that is made up of red blood cells (RBCs). This test is essential in assessing conditions related to blood cell production and overall blood health, helping to diagnose anemia, dehydration, and other medical conditions. The hematocrit value is typically expressed as a percentage, providing insight into the volume of red blood cells in a given volume of whole blood.

In a healthy individual, a normal hematocrit value indicates an adequate number of red blood cells, which are vital for transporting oxygen from the lungs to other tissues in the body. If the hematocrit level is too low, it can suggest a decrease in red blood cell production or an increase in red cell destruction, while a high level can indicate dehydration or conditions that cause increased red blood cell production.
