The Prothrombin Time (PT/INR) panel is a vital diagnostic tool used to assess the blood's clotting ability. Prothrombin Time (PT) measures the time it takes for blood to clot, and the International Normalised Ratio (INR) standardises these results. This panel is crucial for monitoring and managing conditions related to blood clotting disorders, particularly those requiring anticoagulant therapy such as warfarin.

Disruptions in the clotting process can be caused by various factors, including genetic predisposition, liver dysfunction, vitamin K deficiency, or the use of certain medications.

Symptoms of blood clotting disorders may include:

  • Unexplained or Excessive Bleeding: Bleeding that cannot be attributed to an injury or trauma
  • Easy Bruising: Unusual susceptibility to developing bruises even with minor bumps or knocks
  • Frequent Nosebleeds: Repeated instances of bleeding from the nose
  • Prolonged or Heavy Menstrual Periods: Women experiencing abnormally long or heavy menstrual flow
  • Blood in Urine or Stools: Presence of blood in urine (haematuria) or stools (melaena or hematochezia), indicative of bleeding within the urinary or gastrointestinal tract
  • Bleeding Gums: Spontaneous bleeding from the gums, especially during activities like brushing teeth
  • Fatigue and Weakness: Chronic or persistent fatigue and weakness resulting from ongoing blood loss, leading to anaemia and reduced oxygen-carrying capacity

The sample required for the Prothrombin Time (PT/INR) panel is a simple blood draw. A healthcare professional will use a needle to collect a small sample of blood from a vein in your arm. The sample is then sent to the laboratory for analysis.

Once the blood sample is collected, it is mixed with specific reagents and placed into a machine called a coagulometer. The coagulometer measures the time it takes for the blood to clot, providing the necessary information to calculate the PT and INR. The test results are typically available within 10 hours.

If the PT/INR panel indicates an abnormal clotting time or an elevated INR level, it may signify an increased risk of bleeding. In such cases, healthcare providers may adjust medication dosages, recommend lifestyle modifications, or suggest additional tests to further investigate the underlying cause. Treatment plans are tailored to each individual's specific condition and medical history.

  2. Prevention of Excessive Bleeding: Identifying and managing coagulation disorders early can help prevent excessive bleeding episodes and improve overall quality of life.
  3. Improved Medication Management: Regular monitoring of PT/INR levels ensures that medication doses are adjusted appropriately, optimising their effectiveness and minimising side effects.
