Therapy number of heavy and complex disease states requires the appointment of a blood test on the PTI (biochemical blood testing for prothrombin index).As a rule, it is necessary to conduct operations during pregnancy, in the postoperative period, as well as pathologies of the hematopoietic system.In this article, we offer you a closer look at features of the implementation of biochemical blood tests to PTI.

What is the blood test PTI?

It is well known that blood in the human body performs many important functions: transports nutrients and oxygen to organs and tissues, protects against infections, regulates body temperature.Implementation of these objectives is possible due to the liquid state of the blood.Here it is just there such a thing as blood clotting (the ability to form clots).This property of blood and is essential for the body, because in case of bleeding, the bl

ood begins to thicken and form a clot to prevent blood loss.The formation of blood clots and blood clots is due to prothrombin.This particular protein is a precursor of thrombin, has a direct impact on the formation of blood clots.It is for this reason that a second blood clotting factor called just prothrombin.Its production takes place with the participation of vitamin K to the liver directly.

Biochemical analysis of blood on PTI is considered one of the main indicators of coagulation - a special survey, which allows to establish the characteristics of the blood coagulation system.At the present time, experts recommend to conduct biochemical analysis of blood on the IPT in such cases:

  • liver disease;
  • during prolonged therapy with indirect anticoagulants to control bleeding;
  • in testing the screening of blood coagulation;
  • pathology of blood coagulation (eg varicose veins);
  • atherosclerosis vessels;
  • in antiphospholipid syndrome;
  • in autoimmune disorders;
  • state, accompanied by a shortage of vitamin K.

Since prothrombin generated in the liver, IPT enables the operator to assess the state of the patient's body as well as his entire digestive system.In order to avoid false abnormalities in blood test to PTI from the norm, it is essential before you take the material for research to perform the correct preparation.

How to take a blood test on the PTI?

In order to conduct this study a person must not have at least seven to eight hours.The blood should take in the morning on an empty stomach.In the event that this condition can not be performed, doctors are advised to refrain from eating at least four to six hours prior to analysis.In addition, if the patient is treated with drugs that affect blood clotting, it should be sure to inform the specialist to prescribe the direction of the analysis.

We would also like to note that the analysis done on the PTI can be in virtually every hospital in a relatively short period of time.

Deciphering blood test PTI

To determine PTI most commonly used method of Quick.Typically, the rate of blood IPT assay ranges from 78 to 142%.If the patient has any deviations from these indicators, it may be a serious threat to the development of a complex series of pathological processes.

Lowering blood PTI indicates the propensity of the organism to bleeding (anticoagulation) and takes place at:

  • malignancies of the pancreas;
  • violation of protein metabolism (amyloidosis);
  • acute DIC (dysfunction of the blood clotting system and coagulation disorders);
  • lack of clotting factors (congenital);
  • deficit required for blood coagulation vitamin K;
  • bowel disease and dysbiosis;
  • malignancies in the gallbladder;
  • leukemia, chronic and acute course;
  • liver pathologies involving impairment of blood clotting factors;
  • pronounced hereditary or acquired deficiency of fibrinogen in the blood;
  • kidney disease (nephrotic syndrome);
  • too high content in heparin blood (a substance that prevents blood clotting);
  • chronic pancreatitis.

worth noting that while taking some medicines, this indicator may be lower than the rate of IPT in blood tests.Such effects have anabolic steroids, acetohexamide, antibiotics and other medications.

As for the increase in prothrombin index, as indicated by the decoding of blood tests to PTI, the phenomenon is a sign of a hypercoagulable (high blood clotting).It may indicate the presence of diseases such as:

  • malignant tumors;
  • polycythemia (increase the number of erythrocytes contained in blood);
  • acquired or congenital deficiency of coagulation factors;
  • initial stage of thrombosis (blood clots in the deep veins).

Increasing the value of IPT in blood tests can also be celebrated in the treatment of certain drugs (barbiturates, corticosteroids, mercaptopurine, oral contraceptives) as well as during the third trimester of pregnancy.Identify deviations from the norm in the analysis of blood and PTI correctly decipher the results can only be an experienced professional.At the same time it will be to the maximum to take into account the data of his patient the other surveys, as well as the general state of his health.

As you can see, blood test for prothrombin is a very important event, especially for pregnant women (the study is assigned a mandatory, because it helps prevent excessive bleeding or blood clots during childbirth).So be attentive to their health and learn to trust in all the attending physician.
