Learn the importance of pt analysis before any surgery


Before performing any surgical intervention, there are many necessary examinations and tests to be conducted for the patient to ensure that the patient has no health problems that may affect the procedure, and among these tests is the analysis of the prothrombin time, which is sometimes referred to as the PT test or the professional time test, which is a test to assess the speed Coagulation.


Prothrombin is a protein produced by the liver, and it is one of several factors in your blood that help it clot properly.


Most of the time, the prothrombin time is monitored before surgery if there is any concern about his blood's ability to clot.The prothrombin time test can also be done to assess liver disease.It is one of the many tests used to screen people who are awaiting liver transplants. This test is known as the end-stage form of Liver disease (MELD) is a scoring system for assessing the severity of chronic liver disease.


Or if your doctor suspects you have other health problems, such as liver problems or a bleeding disorder, you may need additional tests to confirm your condition.


Obtaining a blood sample for a prothrombin time test usually takes only a few minutes, and like any other blood test, you can get test results within hours.


Test results

The results of the prothrombin time test can be presented in two ways:

In seconds: The average time range for a blood clot is about 10 to 13 seconds A number higher than this range means that the blood takes longer than usual to clot A number below this range means that the blood clots more quickly than usual.


INR: This ratio, which allows easier comparisons of test results from different laboratories, is used if you are taking blood-thinning medications.


In healthy people, an INR of 1.1 or less is considered normal and an INR range of 2.0 to 3.0 is generally an effective treatment range for people taking anti-thinning medications for conditions such as atrial fibrillation or a blood clot in the leg or lung in certain conditions, such as having a mechanical heart valve. You need the INR a little higher.


When the INR is above the recommended range, this means that your blood clotting is slower than required, and a lower INR means that the blood clots more quickly than required.


Blood that clots too slowly can be caused by:

Blood-thinning medications, liver problems, insufficient levels of the proteins that cause blood to clot


A lack of vitamin K, other substances in your blood that impede the work of clotting factors


Blood that clots too quickly can be due to:

Supplements that contain vitamin K, eat large amounts of foods that contain vitamin K, such as liver, broccoli, chickpeas, green tea, kale, and products containing soybeans, and medications that contain estrogen, such as birth control pills and hormone replacement therapy.
