Packed Cell Volume (PCV/Hematocrit)
PCV (hematocrit) is the percentage of blood volume made up by red blood cells. Low values indicate anemia; high values may indicate dehydration or polycythemia. Often included in CBC.

What is the PCV Test?
Packed Cell Volume (PCV) or Hematocrit measures the percentage of your blood volume that is made up of red blood cells. It's a quick indicator of anemia or dehydration. A low PCV means fewer red cells (anemia), while a high PCV can indicate dehydration or conditions where the body produces too many red cells.
Why Should You Take This Test?
Quick measure of red cell mass. Correlates with hemoglobin – PCV is roughly 3× hemoglobin value.
Who Should Get Tested?
Suspected Anemia
Quick assessment of red blood cell volume.
Dehydration Assessment
PCV rises with dehydration.
Dengue Monitoring
Rising PCV indicates plasma leakage in dengue.
Polycythemia Patients
Monitoring excessive red cell production.
