In the procedure of general clinical blood tests (this is scientifically called "leaf with analyzes") is no big deal.
Why You Need
What we renting blood? The doctor should assess the state of our bodywhen we turn to him with complaints about health. And this makes the expert evaluation based on indicators of hemoglobin in red blood cells, erythrocyte sedimentation rate, leukocyte formula. To render the final verdict, the doctor compares the test results with the performance standards - characteristic of a "healthy" blood. Inconsistencies associated with an increase in the percentage of any type of cells in the blood, talking about states, which are formed by adding the name "-iya" endings "-oz" or "-es" to form the name of the corresponding cell. For example, neutrophilia, eosinophilia, polycythemia. The reduction percentages of cells is indicated by adding their names to the end of the "-penem" - neutropenia, hypoeosinophilia.
How to prepare for the taking of blood
our site will remind you of what you need to payattention to the results of tests were as accurate as possible. The blood from the finger pass in the morning on an empty stomach - this means that after the last meal should take about 10 hours. Before going to the clinic, you can drink some water (tea, coffee, dairy products - a taboo). If you have been drinking on the eve of alcoholic beverages, it is best to forget about visiting the lab for a few days. In addition, the day before the procedure, it is not necessary to engage in intense exercise, go to the bath.
What do the numbers
erythrocyte sedimentation rate (ESR) - A healthy person normally keptrange 1-10 mm / hr (male) and 2-15 mm / hr (female). Note that ESR values can be changed under the influence of a number of physiological reasons (meal - up to 25 mm / hour, menstruation or pregnancy - up to 45 mm / h). From increasing ESR anything good we should not wait, it indicates the presence of inflammation in the body. It can be:
- infectious and inflammatory diseases (pneumonia, sepsis, myocardial infarction, tuberculosis. syphilis);
- inflammation as a result of injuries and bone fractures;
In addition, increased erythrocyte sedimentation rate may also be caused by non-inflammatory conditions:
- liver disease;
- kidney disease;
- diabetes, Thyrotoxicosis;
- pregnancy, postpartum period, menstruation;
- poisoning by chemicals (eg, arsenic);
Lowering the ESR is observed at:
- eritremii (benign blood disorder);
- raising the level of bile acids;
- chronic circulatory failure;
- influence of drugs (aspirin, calcium chloride).
White blood cells (WBC). These white blood cells to protect our bodydifferent from uninvited guests - bacteria and viruses. They are larger than red blood cells, but the number is much inferior to them. The rate - 4,0-9,0 x 10 ^ 9 / L. When elevated levels of leukocytes suggests leukocytosis, taking into account its shape. Physiological leukocytosis It can occur in otherwise healthy people likereaction to certain natural state (the last trimester of pregnancy, the last day before menstruation, during breastfeeding, after the hot tubs, a few hours after eating).
Pathological leukocytosis It indicates primarily on:
- acute inflammatory or purulent process;
- bleeding in the brain;
- chronic liver failure;
- the majority of infectious diseases: otitis. meningitisPneumonia.
Reducing the number of white blood cells (leukopenia) - a sign of poor production of young white blood cells in the bone marrow. There is at:
- radiation sickness;
- viral diseases;
- systemic lupus erythematosus;
- cancers metastatic to bone marrow;
- anemia with a shortage of vitamin B12.
Platelets (PLT) - The smallest blood cell plates, but fromno less important. From their normal amount depends on the normal blood clotting and elasticity of blood vessels. Sufficient platelet content is expressed in Formula 180-320 x 10 9 / L.
Thrombocytopenia always indicates the following alarm states:
- violation of formation of new platelets (in alcoholism, anemia, for example);
- accumulation of platelets in the spleen;
- the harmful effects of drugs on brain function.
Thrombocytosis also indicates the presence in the body of chronic inflammatory processes, acute infections, growth of malignant tumors.
After reading the above information youYou can easily find their way in terms of their own blood tests, but remember that prescribe treatment, regardless of your knowledge, should the doctor.
