Low hematocrit may be associated with reduced red cell volume or blood loss. It can be seen in nutritional deficiencies or fluid overload.
Quick summary
Hematocrit reflects how much of your blood volume is made up of red blood cells.
Hematocrit measures the percentage of blood made up of red blood cells.
To assess overall red blood cell volume.
This information is general and not a diagnosis.
Typical reference range: 36 - 52 %
Reference ranges may vary slightly by laboratory.
Low hematocrit may be associated with reduced red cell volume or blood loss. It can be seen in nutritional deficiencies or fluid overload.
A result within the reference range is generally considered typical. Interpretation depends on symptoms and other test results.
High hematocrit may be associated with dehydration or increased red cell concentration. It can be seen at high altitude or with reduced plasma volume.
These summaries are educational shorthand. Doctors still compare the full panel, symptoms, medicines, and the lab's own range.

These are common associations, not diagnoses. Many factors can affect a single result.
A single result rarely provides the full picture on its own.
They are related but different measures. Hematocrit is the percentage of red blood cells, while hemoglobin is a protein within them.

Theme hubs are useful when this result makes more sense as part of a liver, lipid, blood-cell, iron, or kidney-style pattern. If you have several numbers from the same group, you can enter them together there.
Start with CBC-style markers such as hemoglobin, WBC, hematocrit, MCV, and RDW when the question is about blood cell patterns.
