What is Prothrombin Time (PT) test?<\/span>\u00a0<\/span><\/h2>\n

Prothrombin Time test<\/a><\/span>, also known as PT test or Pro-time test, is used to evaluate blood clotting.<\/span>\u00a0<\/span><\/p>\n

Prothrombin is a protein produced by the liver and one of the several substances known as clotting (coagulation) factors.<\/span>\u00a0<\/span><\/p>\n

\"prothrombin-time-test\"<\/p>\n

In the body, whenever there is an injury and bleeding, a chain of chemical reactions occurs in which clotting (coagulation) factors are activated one after another and result in the formation of a clot.<\/span>\u00a0<\/span><\/p>\n

Each coagulation factor must be sufficient and function correctly for normal clotting to occur.<\/span>\u00a0<\/span><\/p>\n

What does the Prothrombin Time (PT) test measure?<\/span>\u00a0<\/span><\/h2>\n

The <\/span>Prothrombin Time test<\/span> measures the time it takes for the blood to clot.\u00a0<\/span>\u00a0<\/span><\/p>\n

It helps evaluate the body’s ability to form blood clots appropriately.<\/span>\u00a0<\/span><\/p>\n

High levels of the test results indicate it takes more time than usual for the body to form clots.<\/span>\u00a0<\/span><\/p>\n

When is the Prothrombin Time (PT) test recommended?<\/span>\u00a0<\/span><\/h2>\n

The <\/span>Prothrombin Time <\/span>test<\/span> is most commonly used to:<\/span><\/p>\n

    \n
  • Monitor the levels when a patient is on a blood-thinning medicine called Warfarin. Warfarin may be prescribed for disorders such as deep vein thrombosis (DVT), atrial fibrillation, pulmonary embolism (PE), or antiphospholipid syndrome.<\/span>\u00a0<\/span><\/li>\n
  • Diagnose the cause of abnormal bleeding or bruising<\/span>\u00a0<\/span><\/li>\n
  • Diagnose liver disease<\/span>\u00a0<\/span><\/li>\n
  • Look for signs of a blood clotting or bleeding disorder<\/span>\u00a0<\/span><\/li>\n
  • Before surgery, if there is a concern about the body\u2019s ability to clot<\/span>\u00a0<\/span><\/li>\n<\/ul>\n

    \u00a0<\/span>What are the symptoms of a clotting or bleeding disorder?<\/span>\u00a0<\/span><\/h2>\n

    The symptoms of a clotting or bleeding disorder may include the following:\u00a0<\/strong><\/p>\n

      \n
    • Easy bruising<\/span>\u00a0<\/span><\/li>\n
    • Heavy menstrual periods<\/span>\u00a0<\/span><\/li>\n
    • Blood in the urine<\/span>\u00a0<\/span><\/li>\n
    • Swollen or painful joints<\/span>\u00a0<\/span><\/li>\n
    • Nosebleeds<\/span>\u00a0<\/span><\/li>\n
    • Unexplained heavy bleeding<\/span>\u00a0<\/span><\/li>\n
    • Leg pain or tenderness<\/span>\u00a0<\/span><\/li>\n
    • Leg swelling<\/span>\u00a0<\/span><\/li>\n
    • Red streaks on the legs<\/span>\u00a0<\/span><\/li>\n
    • Sudden shortness of breath<\/span>\u00a0<\/span><\/li>\n
    • Cough<\/span>\u00a0<\/span><\/li>\n
    • Sharp chest pain<\/span>\u00a0<\/span><\/li>\n
    • Rapid heartbeat<\/span>\u00a0<\/span><\/li>\n<\/ul>\n

      \u00a0How is the Prothrombin Time (PT) test performed?<\/h2>\n

      A blood sample will be drawn from a vein in the arm by a healthcare expert.<\/span>\u00a0<\/span><\/p>\n

      No special preparations are required for the <\/span>Prothrombin Time test<\/span>, though your doctor may instruct you if any specific preparations are needed.<\/span>\u00a0<\/span><\/p>\n

      What are the risks of the Prothrombin Time Studies test?<\/span>\u00a0<\/span><\/h2>\n

      The <\/span>Prothrombin Time <\/span>test<\/span> is a safe, standard test with very minimal risks involved, such as<\/span>\u00a0<\/span><\/p>\n

        \n
      • Bleeding<\/span>\u00a0<\/span><\/li>\n
      • Bruising<\/span>\u00a0<\/span><\/li>\n
      • Lightheadedness<\/span>\u00a0<\/span><\/li>\n
      • Infection<\/span>\u00a0<\/span><\/li>\n<\/ul>\n

        What the results may indicate?<\/span>\u00a0<\/span><\/h2>\n

        The <\/span>Prothrombin Time <\/span>test<\/span> results are presented in two ways:<\/span>\u00a0<\/span><\/p>\n

          \n
        1. Seconds<\/span><\/b>: It represents the time taken in seconds for the blood to clot.<\/span>\u00a0<\/span><\/li>\n
        2. International Normalised Ratio (INR)<\/span><\/b>: INR levels are often used as they make comparing results from different labs and test methods easier. <\/span>If the INR is higher above the ideal range, the blood clots more slowly than wanted, while a lower INR indicates that the blood clots more quickly than desired.<\/span>\u00a0<\/span><\/li>\n<\/ol>\n

          The longer than normal <\/span>Prothrombin Time <\/span>test<\/span> results can be due to:<\/span>\u00a0<\/span><\/p>\n

            \n
          • Low level of blood clotting factors (factors I, II, V, VII, or X)<\/span>\u00a0<\/span><\/li>\n
          • Lack of vitamin K<\/span>\u00a0<\/span><\/li>\n
          • Liver disease<\/span>\u00a0<\/span><\/li>\n
          • Disseminated intravascular coagulation (DIC).<\/span>\u00a0<\/span><\/li>\n
          • Treatment with blood-thinning medicines, e.g.,\u00a0 warfarin or, in rare cases, heparin.<\/span>\u00a0<\/span><\/li>\n<\/ul>\n
