If the patient has problems with blood coagulation, then in such cases, doctors prescribe a blood test for PTI. What kind of research is this? This will be described below. It must be understood that poor blood clotting most often does not pose a great danger, but in some cases can lead to the development of complications.
Coagulability
Usually, an IPT examination is prescribed before surgery, childbirth, and in other situations when normal blood coagulation is extremely important. And what is this process?
By coagulability of blood is meant its ability to pass from a liquid state to a thick one. To ensure the vital activity of the body, it is necessary that the blood be liquid, because it must flow through the vessels, providing normal gas exchange and cell nutrition.
In the event of a vessel injury, bleeding occurs. It is then that the formation of a blood clot (blood clot) is necessary. If the blood does not clot well, the situation is complicated, because it is very difficult to stop the hemorrhage.
There is a special protein prothrombin, which is responsible for the formation of blood clots and coagulation.
Prothrombin index
In order to determine how well blood coagulates, it is necessary to conduct a blood test of PTI. What we will find out further, but for now it must be said that this study helps to determine the prothrombin index.
The prothrombin index is an indicator of the ratio of human blood coagulability to control plasma. Its value is indicated in percent.
In what cases is this study prescribed?
There are several situations in which you need to schedule an examination. In particular:
- Suspected clotting problems.
- Varicose veins.
- Atherosclerosis.
- Functional changes in the liver.
- Blood coagulation screening.
- Insufficient amount of vitamin K in the body.
- Diseases of the immune system.
- Antiphospholipid syndrome.
- When treating the body with drugs such as anticoagulants, blood coagulation is constantly monitored.
You should know that prothrombin is formed in the liver. By determining its quantity, one can understand the state of this organ.
Analysis preparation
An analysis of IPT requires some preparation. Rules must be followed to avoid false results. First of all, you should know that blood should be donated to an empty stomach or not earlier than four hours after a meal.
This minimizes possible deviations. A patient who takes medications that affect blood coagulation needs to be told by the attending physician. He will tell you what to do in a particular situation.
Where can I get an analysis, how much is it?
Now you know, when they recommend a blood test for PTI, that we found out. Now we tell you where it can be handed over? In the event that a person has been prescribed such an examination, he can go to the clinic at the place of residence. It is also possible to carry out the sampling of material for the study of IPT in any paid laboratory. The cost of analysis is low.
Usually it does not exceed 350 rubles. When contacting a private laboratory, a person must understand that each institution sets the prices for analysis independently, so they can differ from each other.
PTI blood test. Decoding, norm
Examination results can be obtained one day after blood sampling. What is the norm of IPT in the patient's blood?
The norm is considered an indicator from 78 to 142 percent. The survey is carried out using the Quick technique. If the figure obtained as a result of the study is too low or, conversely, extremely high, this may indicate the presence of a disease in the patient.
Reduced value
We have already figured out what should be the norm of IPT in the blood. And what does a reduced result mean?
- An underestimated PTI indicates that the body lacks vitamin K. Its deficiency may be associated with intestinal diseases and dysbiosis.
- Liver disease. Congenital organ defects may be present.
- Not enough fibrinogen.
- Oversaturation of the body with heparin.
- Incorrect protein metabolism (this condition is called amyloidosis).
- Kidney disease.
- Leukemia in various forms.
- Oncological diseases of the pancreas and gall bladder.
- Chronic form of pancreatitis.
What does increased value mean?
If you have done a biochemical blood test, the PTI is higher than normal, then this condition is called hypercoagulation. It occurs with pathologies such as:
- The formation of blood clots in the veins is thrombosis.
- Oncology.
- High levels of red blood cells.
Also, high rates of PTI appear in pregnant women in the last few months of pregnancy. The use of certain medications also causes an increase in IPT. These include barbiturates, oral contraceptives, and corticosteroids.
It is impossible to independently determine the reason for the increase or decrease in the percentage of PTI. The decryption of the analysis is done by the attending physician. It is based on indicators of the result of the study and the patient's condition. The doctor also makes a conversation with the patient, during which he finds out what his complaints are. Only after a comprehensive examination of a person is a diagnosis made.
Conclusion
Now you know a lot of useful information about PTI blood analysis (what we found out), the reasons for the violation of normal blood coagulation. We hope you find the information useful.
