Blood, which is a part of the circulatory system; It is a dense, slightly alkaline and red colored liquid. Blood with a pH in the range of 7.35 to 7.45 makes up 8% of the total body weight. It consists of blood, plasma and cellular elements.
RBC
The part of the blood called RBC or erythrocyte constitutes approximately 99% of the formed elements of the blood. Erythrocytes, which have a disc-shaped appearance, carry hemoglobin and enable the exchange of oxygen and carbon dioxide in the body. Hemoglobin consists of iron-containing proteins, which makes up 90% of the total dry weight of erythrocytes. Iron-containing proteins cause hemoglobin to appear red. Because hemoglobin naturally has a red color, these cell types are called red blood cells (Red Blood Cell, RBC, red blood cell).
RBC carries out the exchange of carbon dioxide and oxygen in the body by carrying these gases. In other words, when the person breathes, the oxygen reaching the lungs is bound by the erythrocytes and transported to all tissues and organs in the body. The carbon dioxide gas released by the use of oxygen by the body cells is also bound by the RBC and transported to the lungs. When the person exhales, the carbon dioxide collected by the RBC from different parts of the body is thrown out of the body. All these processes take place with each breath of the person. “What is RBC?” and “What is RBC in blood?” It is necessary to answer the questions. The main reason for this is that red blood cells are composed of an iron-containing protein. RBC produced in the bone marrow consists of cellular elements that make up 40% of the blood. 99% of the shaped elements consist of red blood cells.
The main task of red blood cells is to transport the oxygen entering the lungs to the body tissues and the carbon dioxide released by the use of oxygen in the body tissues to the lungs. The process of producing red blood cells in the body is called erythropoiesis in medicine. As a result of the endocrine glands secreting the hormone erythropoietin, the bone marrow is stimulated. Due to this stimulation, the bone marrow produces 1.5 million erythrocytes every second.
RBC produced in the bone marrow, although it is a nucleated cell at the initial stage, it loses its nucleus in a week when it matures. Loss of the nucleus shortens the lifespan of red blood cells, causing them to die in about 130 days. But at the same time, the lack of core structure adds flexibility to the RBC. Thus, erythrocytes can easily reach all parts of the body. After 130 days, the red blood cells are broken down by the spleen. As a result of the disintegration of erythrocytes, iron mineral is released and this mineral is used again by the bone marrow for RBC production.
Other substances released as a result of the breakdown of red blood cells in the spleen are sent to the gallbladder. The amount of erythrocytes in the blood ranges from 4.2 to 5.4 million in women and from 4.7 to 6.1 million in men. The amount of red blood cells in the blood is determined by the RBC test, also known as the hemogram RBC, which is frequently performed before the person's health checks and surgical operations. Frequently asked questions “What is a hemogram RBC? and “What is an RBC test?” This is how the questions can be answered.
What is the RBC Normal Value?
The test for the measurement of the RBC count, which constitutes approximately 99% of the formed elements of the blood, may be requested in many different situations. One of the values checked in the routine blood count test performed in the presence of complaints of many diseases is RBC. The evaluation of the results of this test, which provides important information about the current health of the person, also differs in each age group. The RBC reference value is different in neonates, infants, early childhood, late childhood, adolescence, and adulthood. The RBC value changes during pregnancy. The RBC reference value also differs between the sexes. Although the RBC normal value varies slightly between the laboratories where the test is performed, it is generally as follows:
- RBC Normal Value in Newborns: The RBC value per 1 microliter at blood level is between 4.8 - 7.2 million.
- RBC Normal Value in Children: The RBC value per 1 microliter at blood level is in the range of 4.6 - 4.8 million.
- RBC Normal Value in Pregnants: Per 1 microliter at blood level RBC value is in the range of 3.42 - 4.55 million in the first trimester, 2.81-4.49 million in the second trimester, and 2.72 - 4.43 million in the third trimester.
- RBC Normal Value in Women: Blood RBC value per 1 microliter at blood level is in the range of 4.2 - 5.4 million.
- RBC Normal Value in Men: RBC value per 1 microliter at blood level is in the range of 4.7 - 6.1 million.
What is RBC in urine?
High RBC in urine means hematuria, which is defined as the presence of blood in the urine. Especially urinary tract inflammation, bladder or kidney infections, presence of kidney stones, prostate enlargement, sickle cell anemia, kidney cancer, bladder cancer, prostate cancer, urinary tract tumor, some drugs used in the treatment of cancer, some types of painkillers, excessive exercise Many different reasons such as erythrocyte can be seen in the urine. Since this condition, which rarely develops due to serious diseases, may be a sign of serious health problems in some cases, the cause of elevated RBC in the urine should be investigated. One of the frequently asked questions is “What is the RBC height?”
What is RBC Height?
RBC value, which is one of the indicators of body health, may increase in some cases. Among the causes of high RBC, factors such as cardiovascular, kidney and bone marrow diseases, as well as sleep apnea, hemoglobinopathy, pulmonary fibrosis, intestinal obstruction, dehydration, carbon monoxide poisoning, protein-enhancing products, doping, smoking and going to high altitudes can be counted. The excess of erythrocytes in the blood, which carry oxygen and carbon dioxide from the lungs to the tissues and organs, is caused by the bone marrow producing more erythrocytes than the body needs. Erythrocyte elevation, which causes many symptoms such as high blood pressure, blurred vision, chest and joint pain, dizziness, headache, tinnitus, abdominal pain, itching, tenderness in the palms and formation of bruises on the skin, is an extremely important finding for the health of the person.
What is Low RBC?
Low erythrocyte, low RBC, anemia or anemia with the commonly used definition among the people, the absence of enough RBC or hemoglobin in the blood level. It is an indicator. Many different conditions such as low RBC, malnutrition, pregnancy, bleeding, some kidney disorders, thyroid disorders, multiple myeloma, epilepsy, types of anemia, leukemia, bone marrow failure, mostly caused by iron, copper, folic acid, B6 and / or B12 deficiency. can also be seen depending on Many different symptoms such as heart rhythm irregularity, sleep problems, shortness of breath, chest pain, headache, dizziness, leg cramps and fatigue may occur in the presence of low erythrocyte deficiency due to abnormal RBC destruction, inhibition of RBC production, bleeding. .
