Why do I need protein C and protein S tests?
You may need these tests if you have certain risk factors. You may be at higher risk of a protein C or a protein S deficiency if you:
Have a family member who has been diagnosed with a clotting disorder. Protein C and protein S deficiencies can be inherited.
Had a blood clot that can't be explained
Had a blood clot in an unusual location such as the arms or the blood vessels of the brain
Had a blood clot and are under the age of 50
Had repeated miscarriages. Protein C and protein S deficiencies sometimes cause clotting problems that affect pregnancies.
