Blood tests: to decrypt


Blood tests: to decryptWhy doctor first sends us to take the General analysis of blood? And how to decipher what is written in the results of the analysis? We found all the secrets of laboratory tests.


To establish or confirm the diagnosis, to detect viruses or confirm their absence, will help the CBC. All because of the blood reacts quickly to any changes in health.





The CBC


Disposable needle-scarificator on the finger pad make easy 2-mm puncture, there is blood, which the nurse collects in the tube and send to the laboratory where special apparatus realizes that contains blood.




The results will help the doctor to make a preliminary diagnosis and to identify the disease at an early stage. But what contains blood?




Red, hot, viscous blood very heterogeneous in composition. It is based on the smallest elements: erythrocytes, leukocytes and platelets.





Erythrocytes


The cells that carry hemoglobin. It is the red blood cells give blood red hue.





Hemoglobin


Hemoglobin is a protein which is responsible for the transfer of oxygen molecules from the lungs to the organs and tissues and carbon dioxide back to the lungs. Men contain blood about 120-160 grams (per liter) hemoglobin, women are slightly less, about 120-140 grams. If hemoglobin is less tissues receive less oxygen and as a result may develop anemia, that is, the anemia.




Symptoms of anemia:




- pale skin.


- fatigue.


- weakness.


- palpitations.




If you have these symptoms, the doctor will confirm the diagnosis, he will prescribe iron supplements and vitamin B12, and will be advised to eat foods that increase the level of hemoglobin: the liver, prunes, carrots, beets, beans, buckwheat, apples and pomegranates.





The erythrocyte sedimentation rate


The average erythrocyte sedimentation rate (ESR) is approximately 10 mm/h for men and 15 mm/h for women. The increase in ESR signals of inflammatory or other pathological process. Increased for no apparent reason ESR should not be ignored!





Leukocytes


White blood cells are called upon to perform a protective function. Normal leukocytes 4-9 billion per liter. If their number is growing, it is a signal about the penetration into the organism of an infection or inflammatory process. However, deviation from the norm may occur with abuse of protein, emotional and physical stress. Even a sharp rise after sleep produces a temporary increase in the number of cells, however, it quickly passes.





Platelets


These cells are responsible for stopping bleeding hemostasis. Due to its ability to stick together in large quantities they provide the clotting of blood. And they, like scavengers, collect on the membrane remains inflammatory wars - circulating immune complexes.




Normal should be 180 - 320 billion platelets per liter of blood. Indicators can vary depending on menstrual cycle, nutrition, lifestyle and individual characteristics. Increased levels of platelet speaks of the tendency to thrombosis and risk of developing cardiovascular disease. Platelets below normal may indicate immune diseases or severe inflammation.





Lymphocytes


Cells of specific immunity. If severe inflammation score drops below 15%, it is important to assess the absolute number of lymphocytes at 1 microliter. It should not be below 1200-1500 cells.





Neutrophils


Their number is approximately 70% of the total number of leukocytes. These cells in large numbers are located in the submucosal layer and mucous membranes. Their main task - the ingestion of alien microorganisms. The increase in the number of neutrophils speaks of purulent inflammatory process. But especially should be alerted if the suppurative process is, and the increase of neutrophils in the blood test no.





Color index


Its rate is determined by the level of hemoglobin in the erythrocytes. The color indicator changes at various anemias: increases in folic acid, and autoimmune aplastic anemia and decreased in iron deficiency.





Hematocrit


Men contain blood about 40-45% hematocrit, women are a little less about 36-42%. Hematocrit shows the percentage of blood cells - erythrocytes, leukocytes and platelets in relation to its liquid part of the plasma.




If the hematocrit falls, people either moved bleeding, or had sharply oppressed the formation of new blood cells. It is with heavy infections and autoimmune diseases.




An elevated hematocrit indicates a thickening of the blood, such as dehydration.





Easyfile


These substances are only 1-5% of the total number of leukocytes. As neutrophils, eosinophils are non-specific immunity. Their increase is characteristic of allergies and parasitic diseases, especially when parasitic infestations.




Before and in the morning before the procedure it is not necessary to starve. For the General analysis of blood it doesn't matter. Of course, do not eat at night greasy heavy food, otherwise indeed, the number of cells will increase. But a light dinner and Breakfast can afford.




You should not pass the examination after drinking, sunbathing and physical therapy, and after x-ray examination. The results can be inaccurate.
