Blood analysis
Blood analysis: is a laboratory test of a sample of blood, in order to obtain information about the physical and chemical properties of blood, to infer some things that help in the diagnosis of certain diseases or for different scientific purposes.
Blood is usually analyzed by pulling a certain amount of it through the vein of the arm, finger or earlobe. In some cases blood cells can also be examined from the bone marrow.
Blood is composed of plasma (a fluid that makes up more than half the volume of blood) in which red blood cells, white blood cells, and platelets swim. Red blood cells contain hemoglobin that carries iron, which transfers oxygen from the lungs to the tissues and cells of the body , While the white blood cells are working to fight alien harmful cells, while platelets are responsible for clotting in some machines Kalnzif.
Importance of blood analysis
Blood analysis provides us with a number of things: determining the number of red blood cells, blood white blood cells along with size and sedimentation rate, as well as the concentration of hemoglobin in red blood cells. In addition, some tests are used to classify blood according to red blood cell antibodies, Blood can also be analyzed to determine the activity of various enzymes, or protein catalysts that are associated with blood cells circulating in blood plasma.
Blood analysis is based on certain characteristics such as: total blood volume, viscosity, coagulation time, acidity (pH), oxygen levels and carbon dioxide.
Some of the evidence provided by the blood analysis as an aid to the discovery of the health situation; as the decline of hemoglobin refers to anemia, but the rise indicates the presence of problems in the lung or in the bone marrow. If the number of white blood cells is low, this indicates a genetic problem or problems in the bone marrow as a result of a viral infection, but if the result is high, indicates the presence of inflammation somewhere in the body, and may indicate the incidence of leukemia.
Decreased number of platelets indicates a viral infection or immune problems, but if there is an increase in their level, it indicates inflammation or a problem in the bone marrow.
Periodic blood tests are essential, especially in the elderly, to prevent and prevent the risk of several life-threatening diseases such as heart disease, cancer and diabetes.
