Prothrombin antibody

Accredited Facility E-report Qualified Specialists

This test is done to detect antibodies directed against prothrombin, an important protein in the blood clotting cascade. These antibodies are associated with autoimmune conditions, particularly antiphospholipid syndrome, and can interfere with normal coagulation. Their presence may increase the risk of abnormal blood clot formation or pregnancy complications.

  • If there is a history of unexplained blood clots.
  • If there are recurrent pregnancy losses or complications.
  • If antiphospholipid syndrome is suspected.
  • If a healthcare provider is evaluating autoimmune clotting disorders.
  • No fasting is required.
  • No special preparation is usually needed.
  • Testing may be repeated after 12 weeks for confirmation if positive.
  • Follow any instructions provided by the laboratory or healthcare provider.
