Low Red Blood Cell Count Normal Hemoglobin And Hematocrit – Anemia is a condition in which the number of red Blood cells (RBC) or hemoglobin is less than normal.
RBCs in the blood have a very crucial role to play because they contain hemoglobin, which carries oxygen to the body tissues. Anemia leads to a host of health complications because body tissues are deprived of the required amount of oxygen to keep them healthy. Thus, victims of anemia often complain of extreme fatigue.

Anemia can be caused by nutritional deficiencies, especially iron and vitamin deficiency. Inherited disorders also cause anemia. Exposure to a particular drug or toxin, and certain types of cancer also cause anemia. Anemia can begin either due to abnormal blood loss, or insufficient production of RBCs or when RBCs are destroyed due to an existing disease.

Anemia is diagnosed after a complete blood count (CBC), which examines the different types of cells in the blood.
Treatment for anemia is aimed at the cause of the condition and its outcome depends on the cause, extent of the condition and general health of the patient. In general, the prognosis is good for victims of anemia.

Red blood cells are produced in the bone marrow and then released into the bloodstream. Normally, they live for 110 to 120 days. Older Red Blood cells are removed from the blood by the spleen and liver.
Microcytic Anemia: Causes, Symptoms, And Treatment
Anemia can occur when the bone marrow does not produce enough red blood cells to replace those that have died. Or it can happen if the red blood cells die or are destroyed more quickly than usual.
Symptoms vary widely. Mild cases often cause no symptoms. The condition can only be discovered during a routine blood test.
Your doctor may also order tests to check for blood in your stool. This can identify whether your anemia is caused by blood loss. Other blood tests check for anemia resulting from a lack of iron or certain vitamins in your diet.
How long anemia lasts depends on its cause and how easily it can be corrected. If the cause of the anemia is only an inadequate intake of iron or vitamin B

Anemia caused by an inherited disease is a lifelong condition. Its impact on a person’s quality of life and lifespan can vary greatly, and depends on the specific hereditary disease and its severity. Some people have no symptoms. Others have severe, persistent symptoms.
Anemia caused by nutritional deficiency can be prevented by eating a y diet or taking a vitamin and mineral supplement when iron or B.
Call your doctor right away if you develop symptoms of anemia. Also call if you notice a yellowish tint to your skin or the whites of your eyes.
If an inherited form of anemia runs in your family, you may want to consider genetic testing before you start a family.
Anemia Classification, Diagnosis, And Routine Workup
The outlook for anemia depends on its cause and severity, as well as the underlying health of the affected person.
Cases that are caused by medications or infections usually go away quickly. Anemia caused by chronic diseases tends to be permanent, but is rarely severe.

What Does A High Red Blood Cell (rbc) Count Mean?

PLUS, the latest news on medical advances and breakthroughs from Harvard Medical School experts. Hematocrit (HCT) refers to the proportion of red blood cells (RBC) in an individual’s blood. Adults with XY chromosomes usually have an HCT that ranges from 40% to 54%, and adults with XX chromosomes have an HCT that ranges from 36% to 48%. In addition to blood cells, 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 done using a capillary tube and a centrifuge (ie a machine using centrifugal force to separate the substances of the blood due to their different densities). Usually, the hematocrit levels are identified as part of a complete blood count (CBC), but they can also be tested alone. However, a CBC is the most common blood test that measures HCT while also measuring the number of red blood cells, white blood cells, hemoglobin levels, and platelets.
Hematocrit is a very useful laboratory finding because having too few or too many RBCs can be a clinical indication of various diseases, such as anemia or polycythemia, respectively. It can also be used to monitor individuals postoperatively to prevent or screen for complications, such as internal bleeding.
Low hematocrit levels, also known as anemia, can be the result of decreased RBC production, increased blood loss, increased RBC destruction, or a combination of these.
Recurrent Anemia In A Patient With Chronic Lymphocytic Leukemia
The most common cause of low hematocrit levels is chronic (eg, ulcers, colon cancer) or acute (eg, trauma, internal bleeding) bleeding that leads to 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 (ie, enlargement of the spleen), where a large number of healthy RBCs are destroyed in the spleen. Another cause of low hematocrit is decreased RBC production, as seen in chronic inflammatory diseases, or bone marrow suppression caused by radiation therapy, malignancies, or drugs such as chemotherapy. Finally, malnutrition (eg, iron, B12, and folate deficiency) as well as overhydration can also lead to decreased hematocrit levels.
Dehydration, due to fluid loss from repeated vomiting, overheating, or limited access to fluids, can cause hemoconcentration. Additionally, low oxygen availability triggers the production of new blood cells to transport oxygen throughout the body and can be caused by smoking; high altitudes; congenital heart diseases; or certain lung disorders, such as pulmonary fibrosis or chronic obstructive pulmonary diseases (COPD). In addition, polycythemia vera, which is characterized by the overproduction of RBC as a result of increased bone marrow stimulation (ie, myeloproliferation), can cause high hematocrit levels. Similarly, increased erythropoietin production, either due to androgen use or due to erythropoietin production by kidney, liver, and ovarian tumors, can also increase hematocrit. Finally, various pathologies of the endocrine system, such as Cushing’s syndrome, can also result in high hematocrit levels.
Hematocrit measures the percentage of red blood cells in the total blood volume. A wide variety of diseases and especially blood disorders can be detected with a hematocrit test. Low hematocrit levels, also known as anemia, can be the result of decreased RBC production, increased blood loss, increased RBC destruction, 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 triggered by various factors.
