High Red Blood Cells Hemoglobin And Hematocrit – Although a high red blood cell count does not always indicate a health problem, in certain cases it can also be a symptom of a disease or disorder.
Red blood cells (RBCs), also called erythrocytes, are the cells that carry oxygen throughout the body. They are also one of the most important components of blood. Having a high red blood cell (RBC) count means that the number of RBCs in the bloodstream is higher than normal.

High Red Blood Cells Hemoglobin And Hematocrit
When you have signs and symptoms of a disease that may involve problems with the production of red blood cells, a complete blood count (CBC), which includes an RBC count, is usually ordered to help with the diagnosis. A complete blood count is usually part of a pre-surgical examination as well as routine physical exams.

Changes in the RBC count also mean that there are changes in the level of hemoglobin and hematocrit in the blood. When the RBC, hemoglobin and hematocrit count is below the established normal range, the patient is said to be anemic. On the other hand, when a person has values that exceed the normal limit, he or she is said to be polycythemic. Too many RBCs can lead to a reduced flow of blood and other related health problems, while too few RBCs can significantly affect the amount of oxygen reaching the tissues.
Healthcare providers may order a CBC when patients show some of the common signs and symptoms of anemia, such as:
This blood test may also be performed regularly to help monitor patients with certain blood disorders, such as chronic anemia, bleeding problems, and polycythemia, including kidney disease.
People undergoing cancer treatment should also have a regular CBC, as radiation therapy or chemotherapy tends to reduce the production of all blood cells in the bone marrow.
Increased Red Blood Cell Volume
The following reference ranges are only a theoretical guideline and should not be used to interpret test results. There may be variations between the reference range and numbers reported by each laboratory that performs the test. Please consult your healthcare provider for the interpretation of your test results.
Although a high red blood cell count does not always indicate a health problem, in certain cases it can also be a symptom of a disease or disorder. Lifestyle and health factors can also cause an increase in the red blood cell count. They include:
This rare blood disease develops when the body produces too many red blood cells (RBCs). When there is an overproduction of red blood cells, blood becomes abnormally thick, making people more likely to develop blood clots. The formation of blood clots can affect the normal flow of blood through the arteries and veins, and cause a heart attack or stroke.
A weakened blood flow also means that the body’s organs are deprived of the oxygen they need to function normally, and can lead to serious health problems, such as angina and heart failure.

Polycythemia vera is a chronic blood disease that can be life-threatening if not properly diagnosed and treated. Although the condition has no cure, there are treatments that can help manage the disease and its complications. Treatment for PV may also involve more than one treatment method to help manage the disease.
The body tries to compensate and increase the production of red blood cells for any medical condition that may cause low oxygen levels. These conditions include:
An abnormally functioning kidney due to kidney disease, kidney transplant and kidney cancer can cause the production of too much erythropoietin, which increases the production of red blood cells.
Certain medications, such as methyldopa and gentamicin can increase red blood cell (RBC) counts. Methyldopa is a drug used to treat hypertension (high blood pressure) and gentamicin is an antibacterial drug used to treat bacterial infections in the blood. Be sure to inform your doctor about the medications you are taking.
Components Of Blood (article)
When a person is dehydrated, the plasma or the liquid component of the blood decreases and increases the red blood cell concentration.
Your healthcare provider may recommend certain medications or procedures to help lower your RBC count, especially if a medical condition is causing the abnormal count.
A procedure called phlebotomy can be done on a regular basis by a healthcare professional until the level of your red blood cells (RBCs) is close to normal. In this procedure, a needle is inserted into your vein to draw blood into a designated container or bag.
In people with bone marrow disease or polycythemia vera, health care providers may prescribe hydroxyurea, which is an anticancer medication that can help slow the production of red blood cells in the body. Regular doctor’s appointments are necessary while taking this medication to monitor and ensure that the number of red blood cells does not drop excessively to dangerous levels.
Hematocrit (hct) Blood Test: High Vs. Low Levels
An elevated RBC count is usually discovered when doctors order blood tests to help diagnose a patient’s condition. You can ask your doctor and discuss the results of your blood tests. Having a high red blood cell (RBC) count and other abnormal test results are some clues that can help your doctor identify the cause of your condition.

Adults with XY chromosomes usually have an HCT ranging from 40% to 54%, and adults with XX chromosomes have an HCT ranging from 36% to 48%. In addition to RBCs, blood has three other main components: white blood cells, platelets, and plasma.

Hematocrit measures the percentage of red blood cells in the total blood volume. A hematocrit test can be performed using a capillary tube and a centrifuge machine (ie a machine that uses centrifugal force to separate the substances from the blood due to their different densities). Usually the hematocrit levels are identified as part of a complete blood count (CBC), but it can also be tested alone. However, a CBC is the most common blood test that measures HCT while also measuring the red blood cell count, white blood cell count, hemoglobin levels and platelets.
Hematocrit is a very useful laboratory finding since too few or too many RBCs can be a clinical indicator of various medical conditions, such as anemia or polycythemia, respectively. It can also be used to monitor individuals post-operatively to prevent or screen for complications, such as internal bleeding.
Low hematocrit levels, also known as anemia, can result from decreased production of RBCs, increased blood loss, increased destruction of RBCs, or a combination of these.
The most common cause of low hematocrit levels is chronic (eg, ulcers, colon cancer) or acute (eg, trauma, internal bleeding) bleeding, which results in significant blood loss. In particular, individuals of reproductive age who are assigned female at birth may have a low hematocrit due to menstruation. However, hematocrit can also decrease due to peripheral destruction of RBCs as seen in conditions such as sickle cell anemia, where RBCs have a shorter lifespan; and splenomegaly (i.e. enlargement of the spleen), where a large number of healthy RBCs are destroyed in the spleen. Another cause of low hematocrit is decreased production of RBCs, as seen in chronic inflammatory diseases, or bone marrow suppression caused by radiation therapy, malignancies, or medications such as chemotherapy. Finally, malnutrition (eg iron, B12 and folate deficiency) as well as overhydration can also lead to reduced hematocrit levels.
Anemia And Hemoglobinopathies
Dehydration, due to fluid loss from repeated vomiting, overheating, or limited access to fluids, can cause hemoconcentration. In addition, low oxygen availability causes the production of new blood cells to transport oxygen throughout the body and can be caused by smoking; high altitudes; congenital heart disease; or certain pulmonary disorders, such as pulmonary fibrosis or chronic obstructive pulmonary disease (COPD). In addition, polycythemia vera, which is characterized by the overproduction of RBCs due to increased bone marrow stimulation (ie, myeloproliferation), can cause high hematocrit levels. Similarly, increased erythropoietin production, either as a result of androgen use or as a result of erythropoietin production from kidney, liver, and ovarian tumors, can also increase hematocrit. Finally, various pathologies of the endocrine system, such as Cushing’s syndrome, can also lead to high hematocrit levels.
Hematocrit measures the percentage of red blood cells in the total blood volume. A wide variety of medical conditions and especially blood disorders can be detected by a hematocrit test. Low hematocrit levels, also known as anemia, can result from decreased RBC production, increased blood loss, increased destruction of RBCs, or a combination of the above. On the other hand, high hematocrit levels can be the result of hemoconcentration, or RBC overproduction, which can be caused by several factors.
