A red blood cell count is a blood test that doctors use to find out how many red blood cells (RBCs) in blood. RBCs contain hemoglobin, which carries oxygen to your body’s tissues.The number of RBCs you have can affect how much oxygen your tissues are receiving.
Since an RBC count is performed as part of a complete blood count (CBC) , results from other components are taken into consideration. A rise or drop in the RBC count must be interpreted in conjunction with other parameters, such as hemoglobin, hematocrit, reticulocyte count, and/or red blood cell indices. An RBC count is ordered as a part of the complete blood count (CBC) , often as part of a routine physical or as part of a pre-surgical workup. When someone has signs and symptoms suggesting a disease that might affect red blood cell production, a CBC that includes the RBC count may help make a diagnosis. Red blood cell indices are blood tests that provide information about the hemoglobin content and size of red blood cells. Abnormal values indicate the presence of anemia and which type of anemia it is.  Description: This test is used to evaluate Magnesium levels in red blood cells. Magnesium is a mineral that is important for strong bones and muscles, heart health, energy production, and nerve function.  1 Hemoglobin (Hgb). 2  The hemoglobin molecule fills up the red blood cells. 3  It carries oxygen and gives the blood cell its red color. 4  The hemoglobin test measures the amount of hemoglobin in blood and is a good measure of the blood's ability to carry oxygen throughout the body. A CBC test usually includes: 1  White blood cell (WBC, leukocyte) count. 2  White blood cells protect the body against infection. 3  If an infection develops, white blood cells attack and destroy the bacteria, virus, or other organism causing it. 4  White blood cells are bigger than red blood cells but fewer in number. The hematocrit blood test determines the percentage of red blood cells (RBC's) in the blood. Blood is composed mainly of red blood cells and white blood cells suspended in an almost clear fluid called serum. The hematocrit test indicates the percentage of blood by volume that is composed of red blood cells. The condition called  anemia  results from having too few red blood cells. A high red blood cell count indicates there are too many red blood cells circulating in your bloodstream. Red blood cells (RBCs), also called erythrocytes, are produced in your bone marrow and transport oxygen from your lungs to tissues throughout your body. A high red blood cell count is generally defined as more than 5.72 million red blood cells per microliter (mcL) of blood for men and 5.03 million per mcL for women. In children, the threshold for high red blood cell count varies with age and sex. The Test. A red blood cell (RBC) count is typically ordered as part of a complete blood count (CBC) and may be used as part of a health checkup to screen for a variety of conditions. An RBC count is ordered as a part of the complete blood count (CBC) , often as part of a routine physical or as part of a pre-surgical workup. When someone has signs and symptoms suggesting a disease that might affect red blood cell production, a CBC that includes the RBC count may help make a diagnosis. A red blood cell count is a blood test that your doctor uses to find out how many red blood cells (RBCs) you have in your blood. It is also called an erythrocyte count. The test is important because RBCs contain hemoglobin, which carries oxygen to your body’s tissues. The number of RBCs you have can affect how much oxygen your tissues are receiving. Definition. A low hemoglobin count is a commonly seen blood test result. Hemoglobin (Hb or Hgb) is a protein in red blood cells that carries oxygen throughout the body. In many cases, a low hemoglobin count is only slightly lower than normal and doesn't affect how you feel. A low hemoglobin count is generally defined as less than 13.5 grams of hemoglobin per deciliter (135 grams per liter) of blood for men and less than 12 grams per deciliter (120 grams per liter) for women. In children, the definition varies with age and sex.
