What is prothrombin time?
Prothrombin time (PT) is one of the basic blood tests that helps assess the functioning of the coagulation system.This is the time needed for the blood clotting process to complete after adding the activating substance.This test measures the time that passes from the moment a blood vessel is damaged until a clot forms.
When to test prothrombin time?What does a PT examination look like and how to prepare for it?
Prothrombin time testing is usually recommended in cases of suspected blood clotting disorders.It may also be performed before surgery to assess the risk of bleeding or before anticoagulant therapy.Special preparation is not always required before the test, but there are situations in which the doctor may recommend discontinuing anticoagulation medications for a short period before the test.
Prothrombin index – normal
Prothrombin time standards may vary depending on the laboratory, but are usually between 11 and 13.5 seconds.To evaluate the results more objectively, the INR (International Normalized Ratio) is used.INR is a standardized measure of prothrombin time, which allows results to be compared between different laboratories.The normal INR range is usually between 0.8 and 1.2.
Prothrombin time – too high
A high prothrombin time, especially in combination with an elevated INR, may indicate a risk of excessive bleeding.The most common cause is the use of anticoagulant drugs such as warfarin.If the prothrombin time is too high, you should consult a doctor who may adjust the dosage of anticoagulants.
Prothrombin time – too low
Too low a prothrombin time may suggest a tendency to excessive blood clotting.It may be related to genetic diseases, liver diseases or the use of certain medications.Your doctor may recommend further tests to identify the cause and adjust your treatment if necessary.
Your suggestions
If you receive prothrombin time results outside the normal range, it is always important to consult your doctor.He is the one who can accurately interpret the results, taking into account the patient’s individual factors.
