According to the results, it is possible to judge the presence of a malfunction of the kidneys, liver, heart and other internal organs. When carrying out a full biochemical analysis explores more than 20 of blood cells.

4. Note the correct position of the body with blood. If the person is worth it, you can increase the indicators of creatinine, cholesterol, alkaline phosphatase, etc. So it is better to sit or lie down on the couch.
