The general or common analysis of a blood - the most widespread kind of diagnostics

A general blood test is a fairly fast, reliable and most complete method of diagnosis, according to which you can say a lot about the state of health.

Correctly to decipher the general or common analysis of a blood on forces exclusively only to the doctor. But today we will also try to do it. First, let's define what the general blood test shows. So, as a result of it, you can find out how fast the erythrocytes settle, the number of erythrocytes and leukocytes, as well as the hemoglobin content and the leukocyte formula.

With the help of this study, we identify such pathologies as blood cancer, anemia, infectious-inflammatory diseases. In addition, you can determine the allergic mood of blood and its coagulability.

And that's not all that the general blood test can say. How to take it? There are no special instructions. It is important only to fulfill one condition, namely before taking blood to not eat. In other words, a general blood test is given on an empty stomach.

Now let's talk about how to decipher some of the indicators of this laboratory study. We will start our review with red blood cells. Normally, a healthy person in the first cubic millimeter of blood contains four and a half to five million. Decrease in this indicator indicates the presence of stress or increased physical activity. This is also possible with prolonged starvation. Elevated red blood cells are a sign of leukemia, congenital heart disease and chronic lung disease. In the event that the amount of red blood cells is significantly reduced, then an additional examination should be performed to identify pathologies such as anemia, leukemia, metastasis of malignant tumors.

Concerning the rate of erythrocyte sedimentation, or as ESR still says, it is important to know the following: this indicator varies slightly between men and women. In the norm of ESR in women does not exceed fifteen mm / hour, and in men - ten mm / hour. Deviation from the norm in the larger side indicates the presence of an acute or chronic inflammatory process. It can be pneumonia, kidney disease, tuberculosis, myocardial infarction, osteomyelitis, poisoning and the like. Sometimes this indicator increases after an operative intervention or as a result of taking medicines.

A low level of ESR is observed with a decrease in muscle mass, fasting, when ingesting corticosteroids.

The next indicator is the level of hemoglobin. For men, this figure ranges from one hundred and thirty to one hundred and seventy grams per liter. In women, it is within one hundred and twenty-one hundred and fifty grams per liter. For children, the norm is one hundred and twenty to one hundred and forty grams per liter. The level of hemoglobin decreases with large blood loss, lack of iron, as well as in the presence of blood diseases. This also includes those chronic pathologies that are not associated with hemolytic diseases.

High level of hemoglobin is characteristic for those people who have pulmonary heart failure, congenital heart disease and some blood diseases. Sometimes hemoglobin increases as a result of some physiological causes, for example, a significant physical load.

So we reached the leukocytes. On average, the blood of a person contains 4 to 9 • 109 / L of white blood cells. They can be of several kinds, namely lymphocytes, monocytes and so on. In the case when it comes to counting all these species, it means an indicator such as a leukocyte formula. The increase or decrease in the level of leukocytes in the blood is always alarming, because it can indicate the presence of a large number of diseases. In this connection, an additional examination will be necessary. Only in this case it will be possible to establish a more accurate diagnosis.

So, as you all could now make sure, a general blood test is a very important research, and it's almost impossible to do without it, because once it is possible to draw appropriate conclusions about the presence of this or that disease and the expediency of carrying out other diagnostic methods.
