Empty stomach

Before a blood test, you must learn a set of rules, compliance with which is impossible without
accurate result.

Advises the physician of laboratory diagnostics, "Independent Laboratory INVITRO" Moscow Alla N. Mikhailova.

- The maximum fine result of the research depends on the level of laboratory where the analysis and on the readiness of the patients themselves. Currently, laboratory doctors prepared specific recommendations for the development that took into account the requirements of international protocols in the field of laboratory diagnostics and European companies - manufacturers of automated laboratory equipment.
Why from a vein?

Take blood from a finger, of course, not so scary and not so painful. But most of all for laboratory brand name viagra testing is taking venous blood. The exception is a narrow range of clinical tests, such as complete blood count. If you need to biochemical research or to determine levels of hormones, it would take at least 2 ml of blood, and this number can be typed only from a vein. Sometimes allowed to draw blood from a finger for a general analysis of the children.
Before or after eating?

Found that on some indices of blood rather sizeable impact may have physical and emotional burden. This can be brisk walking, running, intense climbing stairs.

embassies.

Types of analysis

Accurate picture of the health status allow us to obtain laboratory tests conducted on a regular basis. Up to 30-40 years for this procedure should be used annually, and over 40 - once every six months. In most major laboratories, including "Invitro", you can offer a minimum set of annual preventive examination: l blood chemistry. Determined on 11 core indicators and describes the state of the liver, kidneys, heart, blood vessels, gastrointestinal tract, carbohydrate, protein and fat metabolism. Helps in the diagnosis of anemia, diabetes, atherosclerosis, heart attacks, strokes, chronic inflammation, as well as conditions associated with loss of protein and its redistribution as a result of edema; l common blood and urine tests, determination of C-reactive protein.

It automatically calculates the concentration of red cells, white cells and platelets, and enter the results in memory. In addition, the new device automatically calculates the blood leukocyte counts, estimates the size distribution of red blood cells, white cells and platelets, determines the average hemoglobin content. And, finally, distinguishes normal and abnormal forms of red and white blood cells, which in itself helps to identify a range of diseases. Complete analog device in the world does not exist.
