Analysis of INR. The norm of the blood coagulation system activity

Changes in the external environment now and then lead to changes in the functioning of organs and systems of the human body. Even homeostasis in this case does not always save. Significant changes lead to a disruption in the adaptive capabilities of the human body and the development of a pathological condition. One of the most sensitive systems to such changes is the blood coagulation system.

The International Normalized Ratio (MNO) is the rate of blood clotting. INR as a blood test is performed under various circumstances.

Such a study, in the first place, is shown to people with disorders in the blood coagulation system, as well as when they are suspected. In addition, the INR is analyzed, the norm of which is a sign of the proper functioning of this system, and for monitoring the patient's condition during and after treatment. Doctors recommend conducting such an analysis to all people at least once a year (during the course of preventive examinations).

A patient who undergoes anticoagulant therapy needs this blood test (MNO). The norm, obtained after the study, indicates the effectiveness of the course of therapeutic measures. It is also worth noting that the performance of analyzes should be carried out continuously (regularly). Currently, for the diagnosis it is enough to use a special portable device that allows you to put a sample MNO (the norm of the level of coagulation activity) without leaving home. The test strips used in the stand-alone instrument allow us to determine the index with a high degree of accuracy. A drop of blood is placed on the test strip of the coagulometer, and the result will not be long in coming. Literally in a few seconds it will be displayed on the screen of the tester.

In hospitals and laboratories of diagnostic units, the following tests are used to determine INRs today:

- coagulation test;

- determination of prothrombin time.

Unlike the old days, doctors today know practically all aspects that affect the level of the blood coagulation system of a person. So the indicator "INR norm" can change under the influence of climate change, diet and other changes in the body general nature. In addition, the level of blood clotting is affected by quantitative changes in vitamin K.

Why is it necessary to constantly monitor the value of INR?

The norm of the parameters of the blood coagulation system is variable. It varies depending on age and other characteristics. Control of INR is necessary, because due to eating foods with a high potassium content, significant changes in the activity of coagulation factors are possible.

Particular attention during corrective activity of the coagulation system of therapy should be given to the use of other drugs, because their interaction is almost unpredictable. That is why it is so important to coordinate your actions with your doctor in charge (be sure to inform him about the desire to use a particular pharmaceutical product in the treatment of the disease). Knowing about the interaction of drugs, a competent specialist will give you all the necessary instructions for conducting effective therapy.

Summarizing all of the above, it is worth noting the importance of the coagulating system of blood and changes in it. The possibility of setting up special samples (including using modern stand-alone equipment) makes it possible to quickly and reliably determine changes in the latter. And, as you know, quick and qualitative diagnostics makes it possible to conduct therapeutic manipulations in the early stages of diseases with much greater efficiency.
