About this test

The FACTOR II (PROTHROMBIN) ACTIVITY test is a specialized coagulation study used to measure the activity level of Factor II, also known as Prothrombin, which is an essential protein in the blood clotting process.

Prothrombin is produced in the liver and plays a key role in converting fibrinogen into fibrin, which helps form blood clots. Any deficiency or dysfunction in Factor II can lead to excessive bleeding or clotting disorders.

This test helps evaluate how effectively the blood clotting system is functioning and is often used in combination with other coagulation studies.

  • Detects prothrombin (Factor II) deficiency
  • Helps diagnose bleeding disorders
  • Assesses liver function related to clotting
  • Monitors vitamin K deficiency
  • Evaluates unexplained bleeding or bruising
  • Supports pre-surgical risk assessment

Why Doctors Recommend This Test

Doctors recommend the Factor II activity test when patients experience abnormal bleeding, prolonged clotting times, or unexplained bruising. It is also used in patients with liver disease, as the liver produces clotting factors, including prothrombin.
