Red blood cells carry oxygen to various parts of the body through calcium. Anemia is caused by iron deficiency and can cause fatigue, weakness, lightheadedness and shortness of breath. Iron rich foods include red meat, pork, fish, poultry, lentils, beans and soy foods, green leafy vegetables, and raisins.
Reticulocyte Count Test
Blood is a precious fluid. Plasma, white blood corpuscles and red blood corpuscles are the three kinds of cells in the blood. The blood cells are normally made in the bone marrow. To know the level of red blood cells in the blood, reticulocyte count test is done.
Reticulocyte Count Test
Reticulocyte are immature red blood cells made by the bone marrow. Reticulocytes are in the blood for two days before developing into mature cells. Reticulocyte count test is done to determine if red blood cells are being made in the bone marrow at an appropriate rate. The count indicates how quickly reticulocytes are being produced and released by the bone marrow.
Need for Reticulocyte count test
Paleness, tiredness, weakness, shortness of breath, and/or blood in the stool are symptoms when doctors recommend Reticulocyte count test to:
Reticulocyte count test - Preparation
There isn't any specific preparation required before Reticulocyte count test. However, it is recommended to check with health care provider if any specific pre test preparation is needed. Those who have had a recent blood transfusion should inform the doctor. This can affect test results. Important information to be shared with the doctor is about medicines being taken. Women who are pregnant and mothers who are breastfeeding infants should talk to doctor before opting for the test.
Reticulocyte count test Method
The test result is available few hours after collecting blood or the next day. An elastic band is wrapped around the upper arm to stop the flow of blood. Sample of blood from the vein of the arm is taken. A drop of blood is placed on a slide, smeared, stained and is examined under a microscope. This is the manual method. Automated methods that allow for greater number of cells to be counted are most likely to replace the manual method.
Reticulocyte count test result Interpretation
The number of reticulocytes is compared to the total number of red blood corpuscles (RBC) and is reported as a percentage of reticulocytes.
Reticulocyte (%) = [Number of Reticulocytes / Number of total Red Blood Cells] X 100
In a healthy adult person, the normal range is 0.5% to 1.5%. In kids, the normal range is 3% to 6%. This is a stable percentage. The normal range may slightly vary.
High reticulocyte count suggests more red blood cells are being made by the bone marrow. This could be due to acute bleeding, chronic blood loss, hemolytic anemia, kidney disease and potentially a fatal blood disorder in the fetus or new born - erythroblastosis fetalis (Erythroblastosis Fetalis refers to a serious blood disorder in infants - Rh incompatibility disease and ABO incompatibility disease) or hemolytic disease. Also, the count increases post treatment for certain anemia like iron deficiency anemia, pernicious anemia, or folic acid deficiency anemia.
Erythroblastosis Fetalis refers to a serious blood disorder in infants - Rh incompatibility disease and ABO incompatibility disease.
Low reticulocyte count suggests fewer red blood cells are being made by the bone marrow. This can be due to aplastic anemia or iron deficiency anemia. Other instances such as exposure to radiation, a chronic infection or due to intake of certain medicines (drug toxicity) can lead to low count.
The reticulocyte count increases temporarily during pregnancy. The count is high in newborns but within few weeks the count drops to adult levels. In case the result is abnormal more tests may be administered for further analysis.
Anemia stands for 'without blood' in Greek; When the number of red blood cells (RBC) falls below normal, Anemia is a resultant condition. Hemoglobin is an important constituent of RBC. Hemoglobin usually occurs in the range of 12 and 18 g/dL (grams per deciliter of blood). If the hemoglobin levels show a decrease, anemic conditions set in. Consequently, the various organs and tissues of the body do not receive adequate oxygen on account of the diminished oxygen carrying capacity of the blood. This impairs their normal functioning. Usually women have smaller stores of iron than men. Besides, they also lose blood during menstruation making them primary targets for anemia.
World Health Organization (WHO) defines anemia as a hemoglobin level lower than 13 g/dL in men and lower than 12 g/dL in women. It is essential to be familiar with the typical symptoms of anemia. Often anemia is misdiagnosed and left untreated. An anemic person is likely to feel extremely tired and weak. This is accompanied with dizziness and breathlessness. A person suffering from anemia tends to appear pale and experience feelings of depression. In some cases, anemia can lead to heart ailments too.
Causes of Anemia
Types of Anemia
Iron deficiency Anemia - Nearly 20% adult women tend to suffer from this form of anemia. Loss of blood due to menstruation is not compensated with an iron-rich diet. Pregnancy and breast feeding can also deplete iron stores. Iron deficiency anemia is also noticed during growth spurts or internal bleeding.
Aplastic anemia - When the bone marrow does not produce sufficient quantities of blood cells, aplastic anemia is noticed. Childhood cancers such as leukemia are often responsible for this form of anemia. Other possible causes of aplastic anemia are radiation, cancer or antiseizure medications and chronic diseases such as thyroid or kidney malfunction. Treatment for aplastic anemia involves blood transfusions and bone marrow transplant. This is done to replace malfunctioning cells with healthy ones.
Vitamin deficiency anemia - Low levels of folic acid lead to faulty absorption of iron. Anemia caused due to folic acid deficiency is called Megaloblastic anemia. Pregnancy doubles the body requirements of folic acid and it is imperative that pregnant women take folic acid supplements. Good dietary sources of folate are fresh fruits, green leafy vegetables, cruciferous vegetables, liver and kidney, dairy products and whole grain cereals. Vegetables should be eaten raw or lightly cooked.Folic acid anemia is also a common problem faced by alcoholics. Vitamin B-12 deficiency can lead to a condition of Pernicious anemia. Diseases such as thyroid malfunction or diabetes mellitus can affect the body's ability to absorb vitamin B-12. This vitamin is vital in the production of hemoglobin.
Vitamin C Deficiency Anemia is a rare form of Anemia that is the result of small red cells owing to prolonged dietary deficiency of the Vitamin C.
Sideroblastic Anemia: In this anemia, the body has sufficient iron but it fails to incorporate it into hemoglobin.
Hemolytic Anemia results from high rate of destruction of Red Blood Cells (RBC) at a rate faster than the rate bone marrow can replenish them.
Thalassemia anemia - Thalassemia or Cooleys Disease is a hereditary disorder found predominantly in people of South East Asian, Greek and Italian racial groups. This form of anemia is seen in differing degrees as Thalassemia encompasses a group of related disorders that affect the human body in similar ways. The most common occurrences of Thalassemia are alpha and beta thalassemia. Thalassemia anemia is characterized by symptoms like jaundice, enlarged spleen, shortness of breath and facial bone deformities.
A complete blood count test will test for hemoglobin levels and display an anemic condition. But often anemia is a symptom whose cause lies deeper. The cause and type of anemia will determine the treatment that is needed. A stool test will help in detecting occult blood. Hemoglobin electrophoresis is a blood test that helps identify abnormal hemoglobins. Diagnosing thalassemia or sickle cell anemia becomes possible with this test.
Deficiency can be treated with supplements of iron, Vitamin B-12 and Vitamin C. Partaking an iron-rich diet can be beneficial for those suffering from nutritional deficiency anemia. Seafood, nuts, whole grains and dried fruits such as raisins, prunes and apricots are rich in iron. Ensure adequate consumption of Vitamin C as it aids and stimulates iron absorption. Try and combine citrus foods with iron-rich foods - add tomatoes to a turkey sandwich or chopped strawberries with iron-fortified breakfast cereals.
