What Do Hematocrit Levels Indicate?
Hematocrit levels can indicate a variety of conditions, depending on whether they are high or low.
High hematocrit levels may indicate:
- Polycythemia vera: A condition in which the body produces too many red blood cells.
- Dehydration: A condition in which the body does not have enough fluids.

- Certain cancers: such as leukemia and lymphoma.
Low hematocrit levels may indicate:
- Anemia: A condition in which the body does not have enough healthy red blood cells.
- Blood loss: Bleeding from an injury or surgery can cause hematocrit levels to drop.
- Iron deficiency: Iron is an essential nutrient that the body needs to produce red blood cells.
- Vitamin B12 deficiency: Vitamin B12 is another essential nutrient that the body needs to produce red blood cells.
- Chronic diseases: Conditions such as cancer, heart disease, and kidney disease can lead to anemia and low hematocrit levels.
- Pregnancy: Hematocrit levels can drop during pregnancy due to the increased blood volume.
What Factors Can Affect Hematocrit Levels?
Several factors can affect hematocrit levels, including:
- Age: Hematocrit levels are generally lower in older adults.
- Sex: Men typically have higher hematocrit levels than women.
