What is a hematocrit used for?
The purpose of a hematocrit test is to evaluate the percentage of the blood that is made up of red blood cells.
What does a hematocrit tell you?
A hematocrit (he-MAT-uh-krit) test measures the proportion of red blood cells in your blood. Red blood cells carry oxygen throughout your body. Having too few or too many red blood cells can be a sign of certain diseases.

What is a typical hematocrit?
Hematocrit is the percentage of red cells in your blood. Normal levels of hematocrit for men range from 41% to 50%. Normal level for women is 36% to 48%.
How do you read hematocrit?
The hematocrit is a ratio of the packed cells to total volume. Example: If the column of packed red cells measures 20 mm and the whole blood column measures 50 mm, the hematocrit is 20/50 = 0.4 or (0.4 × 100%) = 40%.
What are symptoms of low hematocrit?
When a person has low hematocrit levels they tend to present with the following symptoms:
- pale complexion.
- weakness.
- fatigue.
- low energy.
- trouble breathing.
- irregular heartbeat.
- cold hands or feet.
What happens if your hematocrit is too high?
If you’ve taken a hematocrit test and hematocrit is high, this means that you have more red blood cells than what’s considered to be healthy. High hematocrit levels could indicate underlying medical conditions like: Dehydration. Carbon monoxide poisoning.
How does dehydration affect hematocrit?
Both the hemoglobin and the hematocrit are based on whole blood and are therefore dependent on plasma volume. 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.
Is hematocrit three times hemoglobin?
Haematocrit (Hct) (%) is usually defined as three times the value of haemoglobin (Hgb) (g/dl), while the clinical definition of anaemia is related to either an abnormal Hct or Hgb value.
What does it mean if a patient has a hematocrit of 60 %?
A hematocrit of less than 15% can result in cardiac failure. A hematocrit of over 60% may result in spontaneous blood clotting.
What is a high level of hematocrit?
If you’ve taken a hematocrit test and hematocrit is high, this means that you have more red blood cells than what’s considered to be healthy. High hematocrit levels could indicate underlying medical conditions like: Dehydration. Carbon monoxide poisoning. Congenital heart disease.
What do you need to know about the hematocrit test?
Hematocrit test. Print. A hematocrit (he-MAT-uh-krit) test measures the proportion of red blood cells in your blood. Red blood cells carry oxygen throughout your body. Having too few or too many red blood cells can be a sign of certain diseases.
How is the hematocrit tube used for blood work?
Hematocrit. Dip the hematocrit tube into the blood and allow the blood to rise to the desired two-thirds to three-quarters level. Because blood cells naturally sediment, a prior thorough mixing of the blood in the tube is necessary to ensure accurate reading.
What does a lower than normal hematocrit mean?
A lower than normal hematocrit can indicate: 1 An insufficient supply of healthy red blood cells (anemia) 2 A large number of white blood cells due to long-term illness, infection or a white blood cell disorder such as leukemia… 3 Vitamin or mineral deficiencies 4 Recent or long-term blood loss More
How does an automated cell counter calculate hematocrit?
Definition. Automated cell counters calculate the hematocrit by multiplying the red cell number (in millions/mm 3) by the mean cell volume (MCV, in femtoliters). When so assayed, it is subject to the vagaries inherent in obtaining an accurate measurement of the MCV (see Chapter 152 ).
