How to stop blood from a finger after it is handed over for analysis

The composition of the blood includes cytoplasm and uniform elements - cells and blood plates. Erythrocytes (red blood cells, pictured) live about three months. Every second 10 million of them die and the same amount is formed. Leukocytes (white blood cells) live from one to half a week. Blood platelets - platelets live only 4 days.

Our blood "stations"

In a healthy person, the composition of his blood is always constant and the number of blood elements is sufficient. And all this thanks to the blood "stations" of our body - red bone marrow, liver, spleen and lymph nodes. At a time when red blood cells are dying - they are destroyed. And only thanks to blood "stations", "fragments" of erythrocytes do not drift freely on our body. Some of them are destroyed by our liver, completely excreted from the body, and some return to the bone marrow to "assemble" new red blood cells. Platelets and leukocytes are destroyed by the spleen.

How the blood is collected from the finger

So, the doctor has assigned you a blood test from your finger. First you need to observe some rules. First, blood is shed from the finger on an empty stomach. Secondly, between the last meal and taking blood should pass at least eight hours. Thirdly, any physical exertion and other studies are excluded before the blood is submitted for analysis. All this is necessary in order that the formula of blood does not change, otherwise there is a risk of distortion of the result of the analysis. Blood is taken from the pincushion of the ring finger. It is better if it is the left finger, since there are many more small blood vessels. In many clinics, the result of a blood test is given to the patient's hands. On each sheet the norm is specified, therefore you independently can compare figures. If something goes beyond the norm - ask your doctor for clarification.
