Description

The PT/INR Blood Test measures how long it takes your blood to clot. This test includes Prothrombin Time (PT) and the International Normalized Ratio (INR), which standardizes results across different labs. It's commonly used to monitor patients on blood-thinning medications (such as warfarin), assess the risk of abnormal bleeding, and help detect liver dysfunction or clotting disorders.

Purpose of the Test

  • Monitor the effectiveness of anticoagulant therapy (e.g., warfarin)
  • Evaluate bleeding or clotting disorders
  • Detect potential liver damage or liver disease
  • Help diagnose causes of easy bruising, heavy bleeding, or blood clots

Who Should Consider This Test?

  • Individuals currently taking blood thinners (e.g., warfarin, Coumadin)
  • Patients with unexplained bleeding or bruising
  • Those being evaluated for liver disease
  • Individuals preparing for surgery or invasive procedures
  • Anyone with a family history of clotting disorders

What the Test Measures

  • Prothrombin Time (PT):
  • Measures how long it takes for your blood to clot.
  • International Normalized Ratio (INR):
  • Provides a standardized result that helps physicians safely monitor patients on anticoagulant medications.

Fasting Required?
