Protein fibrinogen - a soluble and transparent component of blood serum, the basis of blood clots, is formed by the liver, is updated every 3-5 days. When the plasma system of blood coagulation is activated by thrombin, it turns into monomers, which then drop out in the form of insoluble filaments. This is already a fibrin-polymer, of which the thrombus consists. In the transcripts of blood tests, elevated fibrinogen indicates inflammatory processes. As the concentration of fibrinogen increa...
The smallest group of leukocytes are basophils, performing many functions in the human body. In particular, they not only support blood flow in small vessels and provide a migration path for other leukocytes in the tissue, but also effectively affect the growth of new capillaries. If basophils are raised in an adult in the blood, then this indicates the development of the disease - basophilia. The causes of this condition are different, below we will consider the main ailments, because of wh...
The indicator of the level of erythrocytes, leukocytes and platelets on the whole volume of blood in the body is called hematocrit. Usually this indicator is represented as a percentage, less often in the form of a fractional number. The definition of this indicator makes it possible to see the presence of a disease and the degree of its development. The main reason for the increase in hematocrit is an increase in the number of red blood cells (hyperproduction in the bone marrow) or an incre...
Hemoglobin is a complex chemical compound of a protein with an element of iron, which is present in red blood cells.The function of hemoglobin in the human body is one of the most important - it is involved in the delivery of oxygen molecules to all tissues and organs of the body. Oxygen is indispensable for providing the vital activity of a living being with an element, it takes part in obtaining and exchanging energy and carrying out restorative reactions. The effect of hemoglobin is based...
Urea is the final product of protein metabolism, more precisely nitrogen of amino acids. Urea is produced by the liver during protein synthesis, it is removed by the kidneys together with the urine. The remainder of this component in the blood allows you to judge the effectiveness of the kidneys, and any deviation from the norm of the concentration of urea should be alarming. Increased urea in the blood test, as a rule, indicates chronic or acute kidney disease. Very often, against the backg...
Urobilinogen (mesobilirubinogen) - a product of bilirubin reduction. The latter is a bile pigment formed by the breakdown of proteins containing heme. Thus, urobilinogens arise as a result of the utilization of erythrocytes. Urolilinogen is formed in conditions of the intestine from bilirubin, which got there together with bile. Under the influence of enzymes and microorganisms, it is oxidized and absorbed again into the blood. After that, it enters the kidneys and is excreted along with the...
Iron is one of the most important components of blood, which is a necessary component of hemoglobin and takes a direct part in the process of hematopoiesis. A sufficient level of iron in the body is necessary to ensure the process of binding, transfer and transfer of oxygen in the process of blood circulation. Iron enters our body with food, and after digestion in the intestine spreads through the blood vessels. Stocks of iron in the body are deposited in the liver, bone marrow and spleen. T...
Hemoglobin - a complex iron-containing protein in the blood erythrocytes.Takes part in the transportation of oxygen from the lungs to the cells of all organs and the removal of carbon dioxide in the opposite direction. Immediately, it can be noted that a high level of hemoglobin says about the increased clotting of blood, which is not a positive moment. As a result of increased blood viscosity, the likelihood of producing thrombi increases, in addition, oxygen transport is also difficult. To...
Activated partial thromboplastin time (APTT) is a special medical test that simulates the process of clotting blood on the inner way, aimed at assessing the presence of plasma factors, inhibitors and anticoagulants in the blood. It shows the effectiveness of the internal mechanism of blood clotting, allows to diagnose hemophilia and monitor patients undergoing heparin and herdin therapy. APTT norm For an adult, the norm of APTTV is from 21 to 35 seconds. Elongation of APTTV means that the bl...
