What does low hematocrit indicate?
A hematocrit level below the normal range, meaning the person has too few red blood cells, is called anemia. A hematocrit level above the normal range, meaning too many red blood cells, may indicate polycythemia or erythrocytosis.
What causes low hematocrit?

If a patient is severely dehydrated, the hemoglobin and hematocrit will appear higher than if the patient were normovolemic; if the patient is fluid overloaded, they will be lower than their actual level.
What happens if your hematocrit is too low?

What does hematocrit in blood test mean?
HCT. Hematocrit is a blood test that measures how much of a person’s blood is made up of red blood cells. This measurement depends on the number of and size of the red blood cells. Blood transports oxygen and nutrients to body tissues and returns waste and carbon dioxide.
What causes low hematocrit and hemoglobin?

What does a hematocrit measure quizlet?
What does the hematocrit measure? The hematocrit is a commonly performed test that provides the clinician with an estimate of the patient’s red cell volume and, thus, the blood’s oxygen-carrying capacity.

How do you interpret hematocrit results?
Your hematocrit test results are reported as a number. That number is the percentage of your blood that’s made of red blood cells. For example, if your hematocrit test result is 42, it means that 42% of your blood is red blood cells and the rest is white blood cells, platelets, and blood plasma.
