What is RBC in blood tests?

Red blood cells and their tasks
The parameter is the red blood cell count. Red blood cells make up the majority of blood cells. Cells are without nuclei. In normal conditions, their diameter is about 7.5 microns. If the size of the cell is less than 6 microns, the microscrete and, if greater than 9 microns, are called macrocytes.

The shape of the red blood cells
The red blood cells are flexible cells that cling to the capillaries and form the cylindrical mandrel called Rolex.

The size and number of red blood cells
The place is made of these cells in adult bone marrow. Red blood cells are seen in orange yellow under a microscope. Hematocrit is 45-35% in healthy and adult women and 50-40% in healthy and adult men.

The functions of red blood cells
The primary function of the red blood cells is to transfer oxygen from the lung to the tissues for metabolism. Also, the transfer of a part of the carbon dioxide gas to the lung is done by the red blood cells.

RBC increase factors
The number of RBC red blood cells may increase, which is called polycythemia or erythrium, which is two types:

Physiological polycythemia caused by the body's need for oxygen, such as athletes or those at high altitudes.
Polycyclic Vera (True) caused by cancerous cells that cause red blood cells.
In addition, pulmonary disease, or in general any type of disease that causes chronic hypoxia (prolonged oxygen deficiency), such as congenital heart disease

RBC Reduction Factors
GI bleeding or bleeding obvious from the wound, malnutrition and iron deficiency or deficiency of vitamin B12, breaking blood cells, or hemolysis caused by some specific diseases such as Favsym, some genetic problems, such as red blood cells, Dasyshkl and problems, bone marrow, lowers the amount of red blood cells are .

Failure and some kidney problems, chronic diseases and cancer tumors, as well as rheumatoid diseases and eating drugs like chloramphenicol, reduce RBC.

Interesting tips about red blood cells
The red blood cell normally lives in the blood after bone marrow production in the blood, naturally, in the bone marrow, and at the end of its life it is crushed and becomes its constituent elements.
The amount of RBCs naturally appears slightly less during pregnancy, because the volume of blood fluid has increased.
The RBC number is the exact amount of red blood cells in 1 ml of peripheral blood.
Depending on the laboratory and type of kit used, the scale of the cell may vary.
Eating drugs like chloramphenicol also reduces RBC.
