01

Start with fit

Is this the right test for you?

The best test starts with a clear clinical question. These are common reasons a clinician or family may consider this test.

  • ✓Personal or family history of venous thromboembolism (VTE)
  • ✓Unexplained recurrent thrombosis
  • ✓Thrombosis in unusual sites
  • ✓Symptoms suggestive of thrombosis (e.g., limb swelling, pain)
  • ✓Pre-operative assessment for high-risk surgeries
  • ✓Evaluation of potential inherited thrombophilia

In plain language

What this test helps you understand

This test helps identify potential inherited or acquired conditions that increase the risk of developing blood clots (thrombosis). It assesses the function and levels of key proteins involved in the coagulation pathway.
The Thrombotic Risk Screen Test is an important diagnostic tool used to evaluate an individual's risk of developing thrombotic disorders. These disorders can lead to serious health problems, such as deep vein thrombosis (DVT) and pulmonary embolism (PE). Understanding your risk is key for early detection and management, particularly if you have a family history of blood clots or are experiencing symptoms like unexplained swelling or pain.

This test measures several important components of your blood's clotting system, including Protein C Functional, Protein S Antigen (Free), Antithrombin Activity Functional, and Activated Protein C Resistance (APCR). These measurements provide valuable information about how your blood clots.

Individuals who might benefit from this test include those with a personal or family history of blood clots, unexplained limb swelling or pain, those undergoing certain surgeries, or people with known risk factors like obesity or smoking.

Taking this test can help with early detection of coagulation disorders, allowing for timely management and informed decisions about prevention and treatment. Discuss your results with your healthcare provider to understand their meaning and any necessary next steps.
