Introduction
Prothrombin time (PT) of 14 usually means the prothrombin time is 14 seconds, which is within the normal range. It is advisable to visit the hematology department at a hospital promptly for further evaluation, and appropriate treatment should be determined based on identifying the underlying cause. Additionally, if you are taking warfarin sodium tablets under a doctor's guidance, it may typically lead to impaired blood coagulation, resulting in a prolonged prothrombin time during testing.
Prothrombin time (PT) of 14 typically means the prothrombin time is 14 seconds, which falls within the normal range.
The normal range for prothrombin time is 12 to 14 seconds. Prothrombin is one of the key factors involved in the blood coagulation process, and prothrombin time is a common test used to evaluate prothrombin function. This test usually involves taking a certain amount of plasma from the patient and adding calcium ions and thromboplastin, then measuring the time it takes for the blood to clot, which helps assess whether liver disease is present.
If prothrombin time exceeds 14 seconds, it often indicates impaired liver function. Additionally, vitamin K deficiency can also lead to reduced coagulation function and result in prolonged prothrombin time. If prolonged prothrombin time is detected, it's important to promptly visit a hematologist at a hospital to identify the underlying cause and receive appropriate treatment.
Moreover, taking warfarin sodium under a doctor's guidance commonly leads to impaired coagulation function, resulting in a prolonged prothrombin time during testing.
